Vadim Yanitskiy axilirator at gmail.comHi 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. -------------- next part -------------- An HTML attachment was scrubbed...
