Hi Sandi,

According to the attached log, you don't have any clock indications...

Please read the wiki carefully! You are doing wrong.
What are you expecting here? Please refer:

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.

Again, read the wiki:

I just tested the latest versions of OsmoNiTB & OsmoBTS.
Everything works as expected.

With best regards,
