Hi,
I believe I need to keep focusing on osmo-trx support as the gr-gsm app does not seem to support TX (please correct me if I'm wrong though).
You are right, currently it doesn't. But we together with Piotr Krysik are working on TX support for GR-GSM...
I will keep investigating this and I will provide you some patches for osmo-trx which enable power measurement and synchronization.
Great! Having both OsmoTRX and GR-GSM TRX support would be good. I am currently busy with TCH implementation for trxcon, so as soon as I finish, I'll put my development power on this too.
With best regards, Vadim Yanitskiy.
