Hello again, I set up bts like sysmobts but it seems there are some other issues. If I understood it correct I must specify phys_channel_confif for all TS of the BTS. Otherwise OsmoBTS cannot get settings from OsmoBSC. What config should I set for TS2-TS7? And will "slotmask 1 1 0 0 0 0 0 0" affect somehow the OsmoBTS behaviour? Now I can find my networks (sometimes :) but when my phone found it OsmoBTS crashes with the following message...: <0006> scheduler.c:1506 Set a5/0 uplink for SACCH/4(0) on trx=0 ts=0 <0006> scheduler.c:1506 Set a5/0 downlink for SDCCH/4(0) on trx=0 ts=0 <0006> scheduler.c:1506 Set a5/0 downlink for SACCH/4(0) on trx=0 ts=0 <0000> rsl.c:558 (bts=0,trx=0,ts=0,ss=0) Tx CHAN ACT ACK <000b> trx_if.c:397 transceiver (phy0.0) rejected TRX command with response: 'RSP NOHANDOVER -1' <0001> bts.c:208 Shutting down BTS 0, Reason TRX-CTRL-MSG: CRITICAL <0006> scheduler.c:240 Exit scheduler for trx=0 <0006> scheduler.c:216 Init scheduler for trx=0 2017-05-09 23:20 GMT+03:00 Anton Gorbachev <antgorka at gmail.com>: > Hi Vadim! > > Thank you for the comments.
