AW: Order of functions to transmit and receive using layer1

Which are the right few to use? there are only two types of data between L1 and L2: data frames and channel request burst. all the other functions control the radio and the channel in which to communicate. the layer 1 is controlled by the radio ressource protocol (gsm48_rr.c). in order to understand the channel multiplexing, you should read GSM TS 05.02. > Is there any way to send > a text message to a different phone by simulating a base station? osmocom is not (yet) able to control baseband hardware to act as a BTS. > Do I > need two phones or one phone to transmit and receive as a base station? in order to have more than a BCCH, you need two phones. one phone is not able to send and receive at a time. continuouly transmission is required for other phones to find a cell. > Is there any way to make a half duplex base station on a BCCH channel > with only one subscriber phone at a time, and what would that entail > code-wise? you can limit the number of active calls by limiting the number of channels on the BTS, but you cannot limit the number of phones camping on the BTS. > Would it be legal to run a very low power base station in the USA on a different unused cellular band/frequency? you need to check the FCC for laws and test licenses. > I have a lot of > free time since I do school at home and I could probably help develop > some new parts of the osmocom-bb project if you want me to.

You don't have to answer them all if you don't want to. if you are really interested. you should start reading with TS 04.08. this is what i did. it describes all the three "layer 3" protocols.

DSP dump from C116
by Henk 14 Mar '11

14 Mar '11

Hi all, I am trying to get a dump of the DSP code, but after 2 lines of hex the device seems to get stuck. Some watchdog or so, missing something in the initialization sequence? According to the docs the cDSP ID seems to indicate a version B dsp... Any ideas what I can do to investigate? - Henk ./osmocon -p /dev/ttyS0 -m c123 ../../target/firmware/board/compal_e88/compal_dsp_dump.compalram.bin Output: (I had commented the register locations to see if it helped...)

c123 boot wihtout battery
by its sead 13 Mar '11

13 Mar '11

hi list, I would like to run the c123(s) without the LI battery with direct 5V power supply only. Without battery the c123 display just blinks and no PROMPT1 can be received. Anyone knows a way how this might work ? (- like bypass or bridge this 3 pin battery pins) thanks for your help (sorry for the lame add) -- Schon gehört?

Order of functions to transmit and receive using layer1
by Calvin Balke 13 Mar '11

13 Mar '11

I was wondering how to transmit and receive using layer1. I have been reading some of the gsm specs. I have been looking around in the source code a lot, and there many functions that are used for transmit and receive. Which are the right few to use? Is there any way to send a text message to a different phone by simulating a base station? Do I need two phones or one phone to transmit and receive as a base station? Is there any way to make a half duplex base station on a BCCH channel with only one subscriber phone at a time, and what would that entail code-wise? Would it be legal to run a very low power base station in the USA on a different unused cellular band/frequency? I have a lot of free time since I do school at home and I could probably help develop some new parts of the osmocom-bb project if you want me to. I know C, some x86 assembly, and a few other languages. I have also had practice fixing compile-time errors, and bugs in code. I apologize if this is too many questions. You don't have to answer them all if you don't want to. Thank you for helping, Calvin E. Balke

compile errors

Hello everyone, Sorry to bother you all.I am a student and desire to become researchers like you all out there. While building the project osmocom I got an unique error which no-one in the mailing lists have got yet.It says that the header file 'signal.h' is missing in osmocore.I am just uanble to figure it how it is unable to include the header file. please help.By the way I am using the gnuarm-3.4.3 as shown on the osmocom-bb website. roy@roy:~/osmocom-bb$ cd src roy@roy:~/osmocom-bb/src$ make cd shared/libosmocore/build-target && ../configure \ --host=arm-elf-linux --disable-vty --enable-panic-infloop \ --disable-shared --disable-talloc --disable-tests \ CC="arm-elf-gcc" CFLAGS="-Os -ffunction-sections -I/home/roy/osmocom-bb/src/target/firmware/include -nostartfiles -nodefaultlibs" configure: WARNING: if you wanted to set the --build type, don't use --host.

AW: no reception, 3 bars on original firmware

hi calvin, > I am having trouble getting any signal at all. the signal is around -111 > dBm on every channel with the rf gain set on high. The original as harald said, it seems that your phone uses 850 and 1900mhz bands. the filters inside only pass these frequencies. the BTS' in europe use different frequencies than in the US. the current layer23 will only support 900mhz and 1800mhz bands so far. i didn't care about other bands, because i have no way to test it. i can add new bands to layer23. your mail gives me some motivation to implement this finally. the support of DCS and PCS in parallel is quite tricky. maybe i will finish this weekend and you may try that out. regards, andreas

no reception, 3 bars on original firmware

You don't have to answer this right now if you don't want to, it can wait. I have been working on this for a few months. I have never posted on this mailing list before, but I have read many of the other posts. Just so you know, I am currently 14 years old and I have autism(which is the reason why I am obsessed with computers and electronics). I am having trouble getting any signal at all. the signal is around -111 dBm on every channel with the rf gain set on high. The original firmware works fine with an at&t sim card and has 3 bars. The linux distro that I am running is backtrack 4. While trying to diagnose this, I tried mobile and layer23 on a known good channel from a nokia 3100 series phone in netmonitor mode. and in scanning mode on most of the branches that I compiled. I have looked on the wiki and google. I have also tried to figure out how parts of the source code work. I have even tried this on two different boards, the compal_e88 and compal_e86. Has anybody else had this problem? Where exactly is the antenna switch? That could be the problem, if it connects to the headset slot. I have a homemade t191 cable, that uploads the firmware just fine, but I am wondering about the LOST message after the dsp download. What does the LOST message mean? Thank you for your help, Calvin

I found another phone witch looks like it runs Android OS on a MT6516 processor, you can find it here http://www.voldltd.com/sdp/1100371/4/pd-5258987/7588204-2080998/H6_Android_…, it's a VOLD VD-H6. I send them an email but for now no response, I haven't found a ROM to look into it, but the manufacturer is "VOLD Company Limited" and on their website it says that is Android on MT6516, so they need to have the driver for it.
