Anyway, it turned out that the problem was between the chair and the keyboard: I've used wrong branch of Osmo-BTS which was incompatible with my hw.
which branch is the incompatible branch, and which branch are you using now? We have merged osmo-trx support into master in order to get rid of of the need of the nightmare of too many branches. It would be a pity if all that effort was for nothing.
The only issue - no internet on the device, even name resolution fails. Seems like packets are not forwarded properly. What would the best place to poke into user's traffic - see what packets come from which phone and what happens to them and to return traffic?
does the GPRS control plane work, i.e. do you se GPRS ATTACH / ACCEPT, ROUTING AREA UPDATE ATTACH/ ACCEPT, PDP CONTEXT ACTIVATE / ACCEPT?
You can follow this in the VTY logging of OsmoSGSN (logging level for mobility management and session management).
Alternatively, the Gb interface on port 23000/udp can be followed n wireshark. You need to 'decode as... Gb (or was it called GPRS-Gb?)
