Hello, list. My hardware is Umtrx v2.1 and I have already built GSM components: Osmo-trx (branch fairwaves/master) libosmocore (branch: master) libosmo-abis (branch: master) libosmo-sccp (branch: master) libosmo-netif (branch: master) openBSC (branch: fairwaves/master, I use OsmoNITB) osmoBTS (branch: fairwaves/master. Also did ./configure --enable-trx at the installation process) So now SMS and calls work fine. Then I want to get GPRS up. I use master branch of openggsn and master branch of osmo-pcu (osmo-sgsn is supplied with osmoNITN). But when I start osmo-pcu, it says: "PCU interface version number of BTS (5) is different (7). Please re-compile!". After that osmo-pcu aborts. Could you please tell me what branches to use for correct work of GPRS?
Hi,
Try using master branch for all repos instead of Fairwaves/master.

Rodion,
Great that you've got GPRS, calls and SMS working!
There is no single recommended configuration, it all depends on your requirements. Master version of OpenBSC support dynamic switching between TCH and PDCH, but I personally have not tested this yet. Just be aware that TCH/F is currently not working in dynamic configurations - only TCH/H does. I suggest you write to OpenBSC mailing list, as it's a better place for this type of a question.
PS Please don't remove mailing list from CC.

Hello, Alexander.
I've configured GPRS component. So, GPRS work fine:) I also tried egprs mode, works fine. Could you please recomend me the best timeslot configuration? I what SMS, calls and GPRS/EGPRS work. My current timeslot configuration is:
timeslot 0 phys_chan_config CCCH+SDCCH4 hopping enabled 0 timeslot 1 phys_chan_config SDCCH8 timeslot 2 phys_chan_config PDCH hopping enabled 0 timeslot 3 phys_chan_config PDCH hopping enabled 0 timeslot 4 phys_chan_config PDCH hopping enabled 0 timeslot 5 phys_chan_config PDCH hopping enabled 0 timeslot 6 phys_chan_config TCH/F hopping enabled 0 timeslot 7 phys_chan_config TCH/F hopping enabled 0
Is there a better way to configure timeslots in my situation?
