Aalto Koskinen aaltokoskinen at gmail.comHi Vadim and Pau, Thank you for the quick replies. *Pau:* Probably your guess is correct. I am looking into it in detail at the moment the core network configurations. *Vadim*: I started osmo-trx first and waited until the message "Transceiver active with 1 channel(s)", before running osmo-bts-trx and other modules. I will look into the wireshark capture to ensure that there are RSL and OML packets. Yes. I am using the configuration examples from *https://osmocom.org/attachments/3473/nitb.tar <https://osmocom.org/attachments/3473/nitb.tar>.* I am not sure, how to test osmo-bsc is actually running on 192.168.122.1 (I guess, I have to ping to ensure). Meanwhile, is there a basic configuration where I can run the system? Can I find it somewhere(I tried to run /usr/local/etc/osmocom config files and it didn't work. Probably, I have to fine tune the configurations)? And, is there a wireshark trace by any chance for reference?
