I have now built osmo-trx-lms and osmo-bts-trx from source on an i386 platform.

I have beacon, and two phones registered, the configuration from msc and up is the one

I had three weeks ago, which more or less worked, but with large stability problems.

I guess *this* report is the most interesting for you now....

I build from the "master", and target debian9 on i386.

I have not been able to make a call yet, possibly because I might have messed up some

library the MSC is dependent on, but I will work on that.

What is interesting is that bts 0 trx 0 is running trx-uhd with a B100, and seems quite stable.

Moreover, bts 1 trx 0 is running on the i386 and seems happy so far, after 30 minutes.

This is Limesdr mini.

I have just copied the bts0 to trx 0 section from my original config, duplicated it and changed

bts0 to bts1, and the ipa unit-id 1805 0, and of course the ip addresses.

I will comment the various lines in my configs, as I have understood them, and look forward to your

comments, or maybe a keyword list explaining what each parameter is used for.

! here is the first bts - trx section. The ip.access id must match the one in the BTS, where it is called ipa.
