Hi Sandi,
here are the log output from my transceiver : https://pastebin.com/8Y1qXWh8
According to the attached log, you don't have any clock indications...
sudo ./transceiver -a 51 -r 99 ... <0011> trx.c:365 Setting C0 ARFCN to 51 (GSM900)
Please read the wiki carefully! You are doing wrong. What are you expecting here? Please refer:
http://osmocom.org/projects/baseband/wiki/CalypsoBTS#Clock-source
use RSSI or cell_log applications to find cells with good signal and remember the ARFCN numbers. One of them will be used as a clock source for our own base station.
http://osmocom.org/projects/baseband/wiki/CalypsoBTS# OsmoNITB-configuration
Channel configuration
Set a proper ARFCN for running BTS (don't confuse with a clock source). Also, set a corresponding band name.
The AFRCN value, passed to the OsmocomBB transceiver, is a channel of the clock reference cell. The AFRCN value specified in the OsmoNiTB configuration is a C0 channel of the BTS you are going to run. Don't confuse them please.
I also tried with openbts, and the transceiver was terminated after I start ./transceiver -a 51 -r 99.
Again, read the wiki:
http://osmocom.org/projects/baseband/wiki/CalypsoBTS# CalypsoBTS-with-OpenBTS
Run the TRX firmware on the phone as described above. No need to start transceiver, OpenBTS will run it automatically.
The BTS work with Sylvain/testing now, but not with jolly/testing branch.
I just tested the latest versions of OsmoNiTB & OsmoBTS. Everything works as expected.
With best regards, Vadim Yanitskiy.
