Mario Lucas mariolucas75 at mail.ruDear All, I am running a GSM stack: osmo-stp smo-msc osmo-hlr osmo-bsc osmo-bts-trx osmo-trx-lms It seems that my transmitter is emitting radio-waves into air (osmo-bts-trx and osmo-trx-lms communicate with each other through ports 5702 / 5802 — pls see attached printscreen), however i could not make GSMTAP tracing. Osmo-bts-trx does not send GSMTAP messages to port 4729. In most recent version of osmo-bts, GSMTAP tracing is arranged through config file: bts 0 gsmtap-remote-host 127.0.0.1 gsmtap-sapi ccch I could not run the GSMTAP tracing even in previous verions of osmo-bts where you have to specify in synopsis when you call a program: /usr/bin/osmo-bts-trx -s -c /etc/osmocom/osmo-bts-trx.cfg --gsmtap-ip 127.0.0.1 I thought may be i am having some issues in stack components behind osmo-bts for example in osmo-bsc or behind and i tried to run virtual bts. When i tried to run osmo-bts-virtual GSMTAP messages were visible in wireshark (please see attached file osmo-bts-virtual), therefore bts-bsc communication is good. However I still could not figure out why my osmo-bts-trx does not send GSMTAP messages. Or would you advise what log might be helpful to see what i am doing wrong ….
