Dear 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 ….
Thank you for your always helpful assistance

When i try to run osmo-bts-trx i am getting following log in osmo-bsc
abis_rsl.c:142 (bts=0,trx=0,ts=0,pchan_from_config=CCCH+SDCCH4,state=NOT_INITIALIZED) Abis RSL rx CCHAN: mismatching chan_nr=0x90
I tried to find out in bugs:
https://osmocom.org/issues/4872 but could not understand …
i am using
osmo-bsc 1.7.1 and osmo-bts-trx 1.3.3
Could you pls advise me briefly whats happening and how to sort it out ?

My
arm-elf-gcc is gcc version 4.5.2 (GCC)
libosmocore 1.4.1
I believe it is something with libraries but could not figure out ….
