Wrong. What do you mean by 'device'?
I can only receive DL bursts for now.
As soon as I integrate TDMA scheduler, it will be possible
to decode raw bursts to L3 packets and forward them higher
layers.

What do you mean by 'standard stack'?
Some simple applications like ccch_scan already able
to tune SDR to required ARFCN and to start burst detection.
> Do you have some cfile
What for? You can tune to any of surrounding carriers, and
test the implementation against the real networks. Moreover
you can use RTL-SDR while we don't have TX capabilities.

Hi,
> I want to implement a GSM Mobile stack with USRP as RF Frontend.
Well, I am currently working on that. I don't stick on a specific SDR
device like mentioned one.

In case of SDR, DSP part should be done on computer side, like
OsmoTRX does. And some low-level GSM L1 part is already
implemented and could be used by MS implementation too.
If you would like to cooperate me in this direction,
have a look at:
https://github.com/axilirator/osmocom-bb
Right now I am doing some code refactoring, and further
commits will be posted at http://gerrit.osmocom.org/

Hi,
I am trying to write osmocombb to Motorolla c118 phone by following the
given [1] guide.I have successfully compiled firmware binaries but having
issues while writing them to phone.
I connected motorolla c118 via USB Serial To RS232 TTL to 2.5mm audio jack,
using the given guide [2]
When I run this command
$ dmesg | grep tty
I get the following output
[ 0.000000] console [tty0] enabled
[ 14.946936] usb 3-6: pl2303 converter now attached to ttyUSB0
[ 973.747957] pl2303 ttyUSB0: pl2303 converter now disconnected from
ttyUSB0
[ 1484.595816] usb 3-6: pl2303 converter now attached to ttyUSB0
[ 1845.344494] pl2303 ttyUSB0: pl2303 converter now disconnected from
ttyUSB0
[ 2643.566407] usb 3-6: pl2303 converter now attached to ttyUSB1
And on running this
$ sudo cu -l /dev/ttyUSB1 -s 115200
I get a connected message but no further progress is done. When i press
Power button briefly, no activity is shown. I have tried with two phones
but no success on any. I have checked the connectivity between headphone
jack and USB serial chip via voltmeter, it is fine as well. Also tried by
doing Master reset on phone but no use. What can be issue and how can i fix
it. ?
Kindly ignore any mistakes, i am new to this domain, couldn't find much
help on google as well :(
