just to acknowledge this patch from Andreas:

http://bb.osmocom.org/trac/changeset/e7997163b240168301d7d2988f2cd74ae1f397e9/

it fixes the issues I had. Now everything is working again.

Thanks Andreas.

I've now inquired with CCC Berlin, people there seem to be fine with a
bi-weekly meeting on wednesday.  I told them that one CCCB member would
be present at every meeting.  This would likely be me (unless I'm
travelling) so we have to see that somebody else (dexter, prom, roh,
zecke, ...) can fulfill that role during other meetings.

The first meeting thus will be next wednesday, April 11.  I suggest we
meet at 7pm.  A more official announcement will follow.

Subject: Basic build problem.
Message-ID: <CADj1OPAJoroqfsb5oSb8c0gMSvD9KvsVyOn=NTGXiMBdh7KuFg@mail.gmail.com>

Hello,

I'm experiencing problems getting started with building BB and
wondered if someone might be able to advise. Seems that whenever I
specify a toolchain prefix it is ignored. E.g.

$make -e CROSS_TOOL_PREFIX=arm-none-linux-gnueabi-

Results in an error:

"configure: error: in `/home/andrew/Work/AB
Open/Projects/GSM/Osmocom/osmocom-bb/src/shared/libosmocore/build-target':
configure: error: C compiler cannot create executables
See `config.log' for more details"

If I check ./shared/libosmocore/build-target/config.log for instances
of "arm" these are all still "arm-none-eabi", which I do not have.

The prefix example above was to attempt to use CodeSourcery Lite
tools. I've also tried with a prefix of "arm-linux-gnueabi-" to use a
toolchain installed from Emdebian via apt-get, and I experience the
same problem. Although in searching for a fix I read something which
suggested that the Emdebian toolchains may be no use.

So, am I doing something wrong in the first step? And is there perhaps
another toolchain I should be using? Apologies if this has already
been answered ? I have done a bit of searching but only found similar
errors where a prefix was not being specified.

Regards,

Andrew

Thanks for the link. I've done that and was still getting what
appeared to be the same error, and then discovered that this could be
fixed by building from a different directory. Looks like something
doesn't like builds being run from a dir where path has spaces in its
name... See "No such file or directory" error where the path has been
truncated.

Andrew

Message-ID: <726B505068782D49BB803FB7949E62370173A7A94B@MARY.main.mobik.si>

Hi,

I have a question.

When using osmocombb with C118, we are getting error when SIM tries to authenticate itself to the network.
Here are the messages:

<0005> gsm48_mm.c:3902 (ms 1) Received 'RR_DATA_IND' from RR in state location updating initiated (sapi 0)

<000f> sim.c:151 sending result to callback function (type=1)
<0005> subscriber.c:990 key generation on SIM failed (cause 2)

SIM is new. It works if you start phone without osmocom. And It also works if you start without osmocom and when SIM logs into network you restart the phone with osmocom.
We tried several new cards and there was always same result. There is also no PIN set up (SIM is not locked). We tried with USIM.
When we try old cards (>2 years old) osmocom works without problem.

Have you ever encountered this kind of trouble? Is there any fix for it?

Thank you.

Regards,

Alojzij

Interesting. Purely from the "symptoms", I'd guess that the sim starts
in USIM mode and somehow needs to switch into SIM mode to work with
plain old GSM.
My understanding is that the SIM should do that on its own, but
apparently doesn't. And then when you start the official fw, it's
properly switched to SIM mode and then you can start osmocom. (I guess
maybe capacitors keep VCC high enough for the sim to survive a reboot
? altough it still should be reset).

Just a theory ... (and not a perfect one at that).

Do you have a simtrace to make captures of what's on the wire when
talking to the original fw / osmocom and compare ?
Can you spare a SIM ?

Cheers,

    Sylvain

Hi,

we do not have simtrace. Yet.
When we receive simtrace we will be able to read and update you with captures of what is on wire.

We can spare the SIM. It is a prepaid SIM. Why?

I guess you can find a card reader.

Try to generate a Kc with pySim with the script below : (uncomment the
right transport serial/pcsc)

------
#!/usr/bin/env python

import sys

from pySim.commands import SimCardCommands

from pySim.transport.serial import SerialSimLink
sl = SerialSimLink(device='/dev/ttyUSB0', baudrate=9600)

# from pySim.transport.pcsc import PcscSimLink
# sl = PcscSimLink(0)

sc = SimCardCommands(sl)
sc.reset_card()

print sc.select_file(['3f00', '7f20'])
print sc.run_gsm('00112233445566778899aabbccddeeff')
--------


> We can spare the SIM. It is a prepaid SIM. Why?

As a last resort, if remote debug doesn't work you can ship one to me
to investigate what makes it special.
But we're not there yet.

Hi.

We found a card reader but it is not working. We are waiting for a new one.

SIM works if there is no request for PIN or request from network for authentication.
If there is a PIN or authentication request than it does not work.

Would it help if we would send you log files?

Alojzij

Hi.

We received SIMTRACE and made some traces.
I attached them. 

We tried to open it but there was no success with wireshark. Even with your plugin.

In both cases the phone was just turned on. PIN was disabled.

Please check if you see anything unusual in it.

Thank You.

Regards,

Alojzij.

Hi,

is it technically possible to sniff the air traffic (for example with 
ccch_scan from the osmocombb burst_ind branch) and correlate the 
relationship between a burst and a paging request (which contains the 
tmsi of the mobile) ?

Basically: What are the steps to determine which tmsi (mobile) did which 
burst ?

Thank you for your information!

Subject: unmerged patches
Message-ID: <4F81A577.6030109@eversberg.eu>

hi,

i just collected all my patches together that i would have merged:


1. i added two patches to jolly/battery branch of osmocombb. it will add
a font with symbols and display them at rssi. since i did not receive a
reply about that from christian, i pushed it in this seperate branch so
far. christian, if you find the time, just look at it.


2. there are several patches in my "testing" branch at jolly/ui of
osmocombb. these patches are tested and work quite well. the are not
related to the ui. i think they could me mergend:

commit 66c21b3b7d30db205202d46893032ae2a73992a2
    layer23: Send SIM APDUs via GSMTAP
    Usefull to trace SIM messages together with Um messages.

commit b9ff5044a5fcbd07e6a295d75e14c7c504259914
    layer23: Be sure to close mncc socket on exit of mobile instance

commit e30e351d66f07e6effee768412a9d8f31202b4ed
    layer1: Retry fist power measurement, if it seems to fail
    In some cases (e.g. after a call with TCH) the first power measurement
    after a full reset will always return 0 (-110dbm). In this case the
    measurment is repeated once again.
    This is just a workarround, and it will not fix the actual cause.


3. there are several additions and fixes at jolly/rtpmux branch of openbsc.

commit db3a7dd357bd7cd842a80655e734a1b4afdb6f7c and commit
872c6c002add0a741514aa505df9379a6fcdb955 allow to exchange traffic via
rtp with a given rtp endpoint. the destination can be controlled via
mncc interface. the result is that the traffic is not routed via mncc
interface, but directly exchanged with the given rtp endpoint. lcr
supports that, so traffic between sip and openbsc is directly forwarded
and not routed through lcr and mncc interface.

commit 3d407e7c8e5c4e01dc07a530f910d29fac687809 and commit
f47d13e55888576c9201a3a7fee04fc58f98ff66 will handle bad frames from e1
bts. if a frame is bad, the rtp packet is dropped (if forwarded via
rtp). if the bad frame is received by lcr via mncc interface, lcr will
extrapolate the missing audio by repeating last valid frame with reduced
value. instead of having a distrorted sound, the audio stream will now
be clear, even if some frames are bad.

commit 0193b8a76824cdce9d9da3f7374a928efac6f96c allows dynamic payload
types when forwarding rtp traffic to a given rtp endpoint. (used for
EFR/AMR/HR)

commit ea724c6af9e1a5b6df8d0e5965f357896834d3ce and commit
a22e598c0a93f88433c6a00bd2acdde5c2f496d5 will fix the problems with
delay and loosing audio at nanobts. it uses system clock as a basis to
correct timestamp and sequence number of frames transmitted to the bts.

commit bf14b25358f7ceb021e2397e90c2fb9484245b7b fixes problem with
interruption of traffic, if packet transmission via rtp fails in the
beginning.

the result of all these patches is a reliable audio stream. the call
waiting works, as well as hold/retrieve of calls without audio
interruption or increasing/high delay. (even if database access makes
openbsc stop for some time.) in conjuction with lcr, a sip gateway can
directly exchange audio traffic with openbsc. the codec to be used is
negotiated between SIP gateway and MS. (depending on support and preference)


4. long time ago i extraced the sms protocols "smc" and "smr" (TS 11.11)
from openbsc and added a state machines. they are now part of
libosmocore and are used for sending/receiving sms via osmocombb. i
removed all that code from openbsc and use libosmocore instead. see
jolly/sms for the 4 patches.


i hope that was not too much at a time :)

regards,

andreas

I hear what you are saying, and we are working to support inter-BTS
meshing for OpenBTS and OpenBSC.
However, there is also value in getting the phones to mesh, if only
because there are plenty situations where you might not be able to get
a BTS, or be able to use any BTS that is around.

Subject: Sagem OT-290 trace phone / GSMTAP integration
Message-ID: <20120409131637.GE7895@prithivi.gnumonks.org>

Hi all!

Thanks to a generous donor, we have received a couple of OT-290 trace
phones.  These are commercial products intended for taking L2/L3 air
interface traces.  If you've read any of the fabulous GSM papers by
Prof. Dr.-Ing. Joachim Goeller:  The OT-phones is what he used to
generate all his traces.

The majority of what those phones can do is now also possible with
OsmocomBB.

However, OT-290 support GPRS tracing/testing - for CS-1 throguh CS-4.

I would be willing to give away one of the two remaining OT-290 (for
free) to anyone who would in return commit to developing a GSMTAP
interface for it.

The message format on the serial UART between phone and PC is documented
(PDF documentation by Sagem included with the phones).  So based on this
documentation and an OT-290 phone, it should be possible to write a
small command-line program that receives the GSM/GPRS messages from the
OT-290 and sends them via GSMTAP into wireshark.

The result would then be similar to what
http://cgit.osmocom.org/cgit/dct3-gsmtap/ is for DCT-3 phones.

If you're interested, please respond to this message.  Please don't
apply for the phone if you are not able to find the required time and
interest for actually doing the GSMTAP integration.

Thanks!

Hi,
I have been just wondering... would it be possible to use your project
as a base for DIY encrypted cellphone? My idea is that if I could get
hold to output data after voice is encoded by GSM EFR codec, I might
just easily encrypt this digital stream using AES128 and build trully
encrypted cellphone.

Where does actual "analog voice from microphone to digital data"
conversion happends? In a layer1 that runs in a chip, or layer23 that
runs on a PC? If it would be in layer23, encrypting a data stream with
AES 128 whould be doable, am I missing something?

Thanks Marek

Yes, the idea has been raised many times before.

The problem is that in a lot of network the voice is going to be
decompressed in the network, transferred as PCM and then recompressed.

It's actually done lower than layer1, inside the DSP itself.
It is however possible to send custom data (taken from the PC
microphone for eg.). That's what the LCR integration does.

Yes, and in most networks that CSD connection is a kind of beacon, screaming to the network operator, "Hey! Look at me! I'm using a cryptophone! Pay extra special attention to my movements and calling patterns!"

Yeah, CSD is the PITA of the inter-working now that most Mobile Carries
does trunking via Packet Switched and Compressed link.

CSD is dead!

Evviva CSD over CS (Voice)! :P

Yeah, it has been discussed in this thread:
http://lists.osmocom.org/pipermail/baseband-devel/2011-January/000991.html

It would be really nice if you would make some experiment and post the
patch and result.

Especially it would be nice to know the experience when there is
transcoding and when there's no-transcoding between various operator.


It would be very nice to have a 13kbit/s raw channel to be used to
transport encrypted AMR 4.75 audio samples :-)

Subject: Interest in a driver for MT5921 wifi chip?
Message-ID: <201204131547.42617.heiko@sntech.de>

Hi,

Synopsis
--------

I started on a driver for the MT5921 wlan chip from MediaTek and am now trying 
to find developers wo would be interested in this, as I don't have the 
necessary knowledge of the whole wireless part, or to determine if trying 
this is completely futile.

Available is:
- a (hopefully) nearly complete register-map of the chip
- my initial work of basic communication through its spi interface up to and 
including reading the chips eeprom
- a proprietary driver through which it's possible to log the spi-traffic

Also it seems I would be able to provide hardware to interested parties.


MT5921 and MediaTek
-------------------

The MT5921 [1] can be connected via SPI, SDIO, HPI and compact flash. It seems 
to be used mostly in phones based on MediaTek SoCs, but also gained a 
relatively wide spread through the ebook readers from Qisda (Oyo in germany, 
Fnacbook / Sagem Binder in france, bq Avant in spain, Positivo Alfa in brazil, 
Mr. Book in russia, ...).

MediaTek itself does not provide any information about the chip and also 
does not seem to answer inquiries [via various channels] at all.

From talks to some of the device makers, I gathered that MediaTek also
completely refuses to release any material to them. The proprietary driver
mentioned above also seems to have been made by MediaTek directly.


The device
----------

I'm working on the Qisda ebook readers mentioned above (S3C2416 with 400MHz or 
S3C2450 with 533MHz depending on the device). The overall support at this 
point is quite good, including the driver for the epd controller, multitouch-
capable capacitive touchscreen, suspending and resuming the device.

Impressions of these devices can be found on [2].


I have a spare "Oyo 1" that was donated to me, that I could redonate for this
and it seems I could gain the support of one of the device makers, who will 
also supply a small number of devices, if I can find interested developers
for this endavour.


State of the driver
-------------------

The kernel release by Alcatel of their OT890 [3] did include headers describing
most of the chips registers and the eeprom structure of the sdio version. It
explicitly did non include sources for the wifi driver itself.

For things like chip signature and mac address, the eeprom struct also matches
the spi version, so I guess it could match also for most of the non-sdio stuff


On the Qisda devices modifying the underlying spi-dev driver makes it possible
to log the traffic the module sends to and receives from the chip.There also
exists a debug-version of the proprietary module that emits more in-depth
information on what it's currently doing [4].

I also build a crude script [5] to convert these dumps to a representation of
registers and constants form the header. There are probably better tools around
to do such things, but it made the reading of the dumps easier, like:

Array
(
    [mode] => write
    [register] => MCR_RFCR
    [reg-desc] => Receive Filter Control Register
    [valstr] => RFCR_RX_SAMEBSSIDPRORESP_CTRL | RFCR_RX_SAMEBSSIDBCN_CTRL
    [unmatched] => 0x0
)


As written above, bringup of and basic communication with the device
works and I'm lacking the necessary knowledge of the whole wireless part.


So, if anybody is interested in this I would be very happy :-) .


Thanks
Heiko

hi ojenge,

osmocombb supports sms. you can also "sense" RF frequence, but you need 
to add some feature to do measurement at the first plane and then send 
the sms with the results. c123 is capable of receiving GSM downlink 
frequencies only. you may also receive uplink and even (with 
modifications to the firmware) receive frequencies a bit outside GSM 
bands. in this case you need to replace filters or your signal level is 
reduced. the osmocombb firmware is capable of measuring rx levels of 
given frequencies while being idle on a gsm cell. what do you want to 
"sense"?

regards,

andreas

Hi Andreas,
Is my line of interest irrelevant to the OsmocomBB project? In short,
is the project  intending to explore use of the phone for anything
besides the conventional calling and conventional SMS. If you recall,
my interest was to write code to enable the phone to 'sense' and
detect signal from a remote source of few metres. I need to be able to
write the code. Can i?
I need a response desperately so that i stop cluttering the forum.

Hi Andreas,

I need to develop a model that identifies human interaction. I need to
identify the mobile phones that communicate next to a specific mobile
phone consistently. it would show the acquintances of the owner of the
specific mobile phone. The specific mobile phone should therefore be
able to sense signals from the nearby phones. those phones which
signals are always powerful must be next to it always.
I need to harvest the received signal of the specific phone. The
received signal must have been down-converted and digitized in order
to be accessible to a program that i design. The program would detect
the identity of the nearby phones and send an SMS to a control centre
for analysis. the c123 must enable me do this.

hi ojenge,

you need to perform two steps:

1. you need to alter the neighbour cell measurement task in 
mobile/gsm322.c, so it will not measure neighbour cells in idle mode, 
but measure whatever you like. you can define up to 32 frequencies. 
after you've received the results, you can keep them, change them or 
change them back to start over, until you have measured the full range 
you want. you must give <ARFCN> + ARFCN_UPLINK in order to measure other 
phones.

2. as you have a complete set of frequencies you wanted to scan, you 
need to generate an sms with these results.

note that you cannot sync nor read any messages from the surrounding 
phones with the neighbour cell measurement task. you just get the rx 
level of what passes through the filters.

also note that the current code will only run on a host, so you need a 
laptop/netbook/embedded hardware to use the c123 with osmocombb.

i suggest start reading the gsm322.c, it does most of the idle process.

regards,

andreas

Hi Andreas.
Much appreciation, but one more question. Can OsmocomBB code recognize
any other signals which are non-GSM in the neighborhood of the c123,
for instance, signals generated by radio/TV receivers? How can it be
made to recognize them?

Dear Chengcheng,

it is nice you are interested in OsmocomBB but please be more verbose in your
emails. E.g. how does OsmocomBB (the wiki, the code, the documentation, the
awareness) benefit from somebody giving you free support?

Regarding your question, the Mobile Station has no direct connection to the
SS7 network, so a phone can not query a HLR.

you cannot implement it as you need SCCP access, i.e. be a mobile
operator.  Also, this is off-topic on this mailing list, as it is
completely unrelated to development of a Free Software baseband protocol
stack.

Subject: CKSN clarification
Message-ID: <4F917C25.5000707@fairwaves.ru>

Hello.

CKSN - Ciphering Key Sequence Number is associated with Kc and is a bit trickier than
trivial counter.

According to GSM 04.08 (p. 278 in v5.3.0 in my case) it's comprised as follows:
* 3 bits - actual key sequence (value 111 seems to be reserved)
* 1 bit - always 0
* 3 bits - CKSN IEI

Could you help me to understand how to properly generate it:
- the last bit (8th) is not specified - does it mean it's always 0?
- what is CKSN IEI and how do I calculate\use it?
- am I right that 3-bit key seq. value is simple counter that I increment with each
Kc generation?
- what do I do when key seq. reach 6 - start over with 0 again?

And of course I'm interested if CKSN-related code is available as part of libosmogsm
or some other open source project: the code is always helpful in understanding and I
don't have to reinvent the wheel :)

best regards,
Max.

No it's not ... it's really just a counter. Just with 1 bit fixed to 0
and a a reserved value.

7 is reserved as "invalid". When the MS sends that, it means it has no
Kc whatsoever to re-use.


> - what is CKSN IEI and how do I calculate\use it?

It's nothing. Really. For whatever reason when they describe an IE
they add this "IEI" field which is nothing but documentation. Don't
worry about it, just consider it's not there and the CKSN is 4 bits
only.

Sure. But you can actually count in any way you'd like. The only
requirement is that you don't reuse the one sent by the phone and you
don't use 7.

OpenBSC handles the key_seq in the authentication procedure. But there
is really nothing to it.

IEI is a Information Element Identi?er, which is a part of TLV-coded
(Type-Length-Value) Information Elements (IEs). In other words, IEI
represents type (T) of the data payload which follows it. TLV is an
encoding used in most of the classical GSM protocols. I don't recall
where it is described in the Standard, but here is a nice paper which
you easily find on Google which describes ciphering and described TLV
structure as well (section 6.1.2):

But as Sylvain mentioned, in almost all cases CKSN is sent as "V" IE,
so no IEI is needed. The only place where you seem to need CKSN IEI is
in GPRS Mobility Management Messages "Authentication and ciphering
request" (section 9.4.9), where it CKSN is sent as "TV" IE. And there
in the table left column you see the IEI value "8-", meaning that it's
"8-in-the-MSB".

Subject: Basic Set Up For PCS 1900
Message-ID: <1335005277867-3927952.post@n3.nabble.com>

Hi all:

I've been on and off trying to set up Osmocom-BB for quite a while now. I've
tried using several Cxxx with no luck of being able to lock on to a cell. I
shifted to Pirelli_dpl10 hoping to avoid configuration change required of
dual-band phones to work with Osmocom-BB but no positive outcome.

I'm using Sylvain testing branch with transmit enabled; create mobile config
file with PCS1900 and GSM850 as the only bands to be supported. For US
Motorola dual band phones c139 and c155, I modified the required section of
the rffe file to support PCS1900; and for Pirelli, I made the recommended
modification to UART option before being able to communicate with the
device. I guess I did all what need to be done for preliminary setting.
Layer1 load perfectly but mobile application never work.

Sim reader worked perfectly; Sim information was read, mobile app used the
previous PLMN information to start power measurement. I was able to get
average power of -92dB with Pirelli but while still performing the scanning
the result output repeatedly fix prim_pm.c file with value to be overwrite
message.

I guess the issue has to do with passing the right parameters to layer1 to
perform ARFCN scanning in order to obtain power measurement of the available
channels. I'm not really sure if there is need to modify any part of layer1
or Rita files before accurate measurement could be done for PCS1900.


I'm not that deeply knowledgeable in GSM standard but I can still figure out
what to do if any hint
is given toward what need to be done before PCS1900 band will work with any
osmocom-compatible phone.
I know that some people have worked on PCS1900 and GSM850 but there is no
information
towards what need to be done in terms of specific file to hack to change
default GSM900 and DCS1800 bands configurations to GSM850 and PCS1900.

I am pretty much sure that If I were in Europe I would by now step up from
trying to make Osmocom lock to a serving cell to the point studying the code
to work for a specific purpose. I am using the project as part of thesis
work to analyze the Um interface and to explain processes that occur between
BTS and mobile station.

I will so much appreciate it if anyone could be of any help. Thanks.

Subject: April 25, 7pm / Regular Osmocom meeting in Berlin?
Message-ID: <20120423205451.GS4592@prithivi.gnumonks.org>

Hi all!

This is the announcement for the 2nd incarnation of our bi-weekly
Osmocom Berlin meeting.

	April 25, 7pm @ CCC Berlin, Marienstr. 11, 10113 Berlin

The schedule is as follows:

19:00	Introduction into the TETRA base station located @ CCCB 

	For quite some time, there is a full TETRA base station located
	in the Berlin CCC, consisting of two base radios (BR), a site
	controller (TSC), an auto-tuning cavity combiner and other
	equipment.  The talk will introduce the architecture of the
	system and the current status of getting it running.

20:00	Presenting the CC32RS512 / towards an Osmocom Card OS

	The CC32RS512 is a flash-based smart card controller to which
	the documentation is available without NDA.  This means that we
	finally are able to implement a Smart Card OS (COS) as free
	software.

20:30	Informal discussions


If you are interested to show up, feel free to do so.  There is no
registration required.  If the initial part is not interesting to you,
feel free to join us later at 20:30.  The meeting is free as in "free
beer", despite no actual free beer being around ;)

Regards,
	Harald

Subject: Osmocom RRLP
Message-ID: <66a74c18caeeefb9163aff0b7beea11a.squirrel@calmail.berkeley.edu>

To whom it may concern:

Has anyone implemented RRLP request handling in osmocombb's layer 3? We
are particularly interested in the transmission of GPS data.

Additionally, if anyone has any helpful advice/documentation on the
message format which is more detailed or useful than the gsm 04.31 spec we
would greatly appreciate it.

Thanks you,
Max Feldman

Subject: PLMN Scan Rate when off network
Message-ID: <CACyT-3kdnmzVorvD=VQ6Up0PqvXO6DRs+haPuPM44=7jh9mXwQ@mail.gmail.com>

Hi Baseband,

I'm trying to figure out if there's any standard set for how often a
handset should scan for signal when out of coverage. I haven't been
able to find much, just the following in 3GPP TS 22.011:

3.2.2.2 At switch-on or recovery from lack of coverage
If registration cannot be achieved on any PLMN, the UE shall indicate
"no service" to the user, wait until a new PLMN is detected, or new
location areas of an allowed PLMN are found which are not in the
forbidden LA list(s), and then repeat the procedure. When registration
cannot be achieved, different (discontinuous) PLMN search schemes may
be used in order to minimize the access time while maintaining battery
life, e.g. by prioritising the search in favour of BCCH carriers which
have a high probability of belonging to an available and allowable
PLMN.

Sounds like it's up to each manufacturer to just pick a delay? Any
other thoughts/intuitions which might help us bound this number?

Thanks!

Message-ID: <CAGPHiNmRtN-4GQKtMxySuZO3ecppmzcxK=L3yiDNOMAm1N9Aqw@mail.gmail.com>

Hello,

Hopefully this question is appropriate on this list (please let me
know otherwise).

Running ccch_scan or bcch_scan in the sylvain/burst_ind branch, I keep
getting this error:

<000c> l1ctl.c:114 FBSB RESP: result=255

I tried checking the code, but I can't quite figure out what's going on.  It
looks like 255 is an error code, but I don't know where to go from there.

This may be related to my SIM card being locked (I think).  Running mobile on
the sylvain/testing branch, I get:

<0005> subscriber.c:625 PIN is required, 3 tries left

Will not having the PIN intefere with ccch_scan as well?


Thanks,

Josh Pereyda

bcch_scan doesn't make sense on burst_ind. Only ccch_scan is meant to
do anything useful, all the other apps may do random things becaue
they're not meant for use in burst_ind.

It just means failure to sync ...

Most likely the ARFCN you gave doesn't carry a valid C0.

Note that it's only tested on 900/1800. US band support is not tested
and probably not functional especially in burst_ind. Fixing it is left
as an exercise to the reader ...

No.

Hello All,


What is the preferred Sim Card Reader/Writer for the SysmoSim Card,
A.K.A., the GrCard Sim?

And is the following known to work reliably with the SysmoSim Card?
SIM Reader kit - v1.0http://www.adafruit.com/products/101I contacted
Adafruit.com yesterday and they explained that their device
doesn't work on all Sim Cards.

Any assistance would be greatly appreciated.

Sincerely,

You can use just any PCSC supported smart card reader, preferably a CCID compliant USB reader.
OmniKey is a reference, but the pkey smartcard reader (a bit cheaper, with lots of clones) is also very handy.

There is no "preferred reader".  Any reader compatible with ISO 7816-2
an -3 should work with the SIM Card.  Otherwise, how would one make sure
that the sim card works in all phones?

Well, then _they_ should be able to explain why that is, and what
exactly those restrictions are.

I would strongly recommend for a device that claims compliance to the
ISO 7816 specs.  And I would go for a reader that supports USB-CCID and
is compatible with libccid / pcsc-lite on Linux:
http://pcsclite.alioth.debian.org/ccid/supported.html

Subject: Frequency hopping
Message-ID: <CAOYJJfszFeRYx2e1A0hXu0Z0=JmMnm6ed6mgjUpBAFCCgJ4i0Q@mail.gmail.com>

Hello everybody
What happens when a mobile station is in a cell that uses hopping, but the
mobile locks to that cell (for instance using the function of the
engineering menu of a BB)? Is the hopping mandatory  or the ms can continue
working also without it?
Does osmocom support hopping? What are the commands of the mobile interface
(if they exist) to show how the hopping is going? Is it possible to lock
with osmocom too?
Thanks for the answers.
Dario.

Hi,

"Cell Locking" is only for IDLE mode, when selection which ARFCN to
camp on (broadcast channel).
Hopping is only for dedicated channels.

One has no influence on the other.


> Is the hopping mandatory ?or the ms can continue working also without it?

Mandatory. If the MS received an ASSIGNEMENT command with hopping
enabled it has to follow it. (or loose signal ...)


> Does osmocom support hopping?

Yes


> What are the commands of the mobile interface
> (if they exist) to show how the hopping is going?

I don't think there is any. But in the log when following the
assignement command you should see some info about the multiple ARFCN
if there is hopping.


> Is it possible to lock with osmocom too?

Look at the 'stick' option in config.


Cheers,

    Sylvain

Spend a lot of hours starring at the disassembled DSP code and

with UI (inspiration)? steve: framebuffer is mosly compatible

I wasn't aware of all that.
Also I don't have much details on what was said since I wans't there...

Should me and Alan Carvalho de Assis continue the work we are doing?
What is the current plan?

our status is here: http://bb.osmocom.org/trac/wiki/nuttx-bb/drivers

The current work on my side is to:
 * make serial work without sercomm(done locally,just some configuration 
change)
 * unbreak the booting of the calypso(require serial to work without 
sercomm,the commit that created the problem has been identified, how to fix is a 
work in progress)
* I also tried to change toolchain(I generated a toolchain with openembedded)  
to see if it fixed the issue but according to Gregory it's not the right fix.
* I also identified some dummy functions in the nuttx version of sercomm that 
we should get rid of.

On Alan Carvalho de Assis side :
he's trying to make the keypad work but he has some difficulties with it.

Hi Denis,

there was no decision on OsmoDevCon, apart from some opinions.

I'm not aware of anyone actually having reviewed/evaluated rockbox at
this point.

The general point was that we apparently don't really _need_ a "full OS"
like NuttX, but there are other solutions like rockbox that may bring in
other useful parts like a UI for low-resolution dot-matrix displays.

I guess until somebody actually tries and experiments with an early port
of rockbox to the calypso, we won't know what is the best way to move
forward :/

And in general, everybody seems to be busy with lots of other things, so
I'm not sure if (and when) that might happen.

Regards,
	Harald

Hi, all,

Of course, I am not impartial, but I do want to point out two things.? First, there appears to be some misconception that NuttX is big and heavyweight.? That is certainly not true.? Most implementations use only about 40Kb or so (depending on the features that you incorporate).? And you can get it as small as 12Kb; it will run on a z8 or an 8051 or an AVR with 4Kb of RAM.? That 40Kb footprint is for a complete environment that might include displays, USB, networking, filesystem, support etc.? Well, if you include everything it pushes about 50Kb.


So I have trouble understanding that the issue there.? And secondly, NuttX does have a rather complete graphics capability.? Probably the best in class:


1. A window system like a tiny X? that is scalable from a single thread solution to a full multiple NX server (see http://nuttx.sourceforge.net/NXGraphicsSubsystem.html 
and 
http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/nuttx/graphics/),

2. An extensive "widget" for adding buttons, textboxes, etc. to NuttX.? This has only been 
released to open source recently but is fairly matured because it has 
been integrated into commercial products 
(http://nuttx.sourceforge.net/NxWidgets.html and 
http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/NxWidgets/).


3. Finally, I am currently developing a tiny window manager that I am calling nxwm.? This was 
inspired by the Matchbox Window Manager concept:? That is, it is truly 
multiple window manager but only one window is display in time.? This 
simplification helps performance on LCD based products (in the same way 
that a tiled window manager helps) and also makes the best use of small displays.? It is awkward trying to manage multiple windows on a small display.


nxwm is oriented toward tiny screens with touch capability.? It supports a 
task bar and a start menu with the normal meanings.? I have only been 
working on this for about 3-4 days,and I don't expect to have this 
complete for another week or so.? But it is something else that you 
should be aware of if graphics support is important to you.

The code is growing here:? http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/NxWidgets/nxwm/.

But I find that RTOSs tend to be religious topics.? People get strong opinions with very little information. So other than providing all of the information that I can and providing the best support that I can, I am not involved in this decision.

Hi Denis,

there was no decision on OsmoDevCon, apart from some opinions.

I'm not aware of anyone actually having reviewed/evaluated rockbox at
this point.

The general point was that we apparently don't really _need_ a "full OS"
like NuttX, but there are other solutions like rockbox that may bring in
other useful parts like a UI for low-resolution dot-matrix displays.

I guess until somebody actually tries and experiments with an early port
of rockbox to the calypso, we won't know what is the best way to move
forward :/

And in general, everybody seems to be busy with lots of other things, so
I'm not sure if (and when) that might happen.

Regards,
??? Harald

Hi Harald,

First all sorry top-posting...

NuttX also have support to dot-matrix displays, see this "mp3 player"
running NuttX:

Best Regards,

Hmmm... I did that too.

I'm not certain, but I don't think that this example is using any of the
 NuttX graphics facilities.? I am not sure what he is doing, but the 
fonts don't look familiar (NuttX supports 17 different? Helvetica and Times Roman 
fonts) and the drawing certainly does not come from Nuttx.? I don't have
 any good demos of the graphics from NuttX but they are all rendered as 
"3-D" images.? I've attached the output of the button array unit test to
 give you a better idea of what I mean.

(That attached PNG came from here: 
http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/NxWidgets/UnitTests/CButtonArray/cbuttonarray.png?view=log)

This button array, by the way, can used with a touchscreen as an 
on-screen keyboard (with the output going to an edit box).? "Widgets" 
like this have already been used to implement the complete GUI for a 
medical device.
