Can't to connect sysmobts-v2(sysmobts-v2 3.10.50-g9610e79) to osmoBSC(latest version).

You mention osmo-bsc here, but the ticket was created in OpenBSC project. I assume you meant osmo-bsc, not deprecated osmo-nitb.

I am assigning this ticket to pespin who worked on the related FSMs and knows a lot about this topic.

#2 Updated by eugeneb2008 about 1 month ago

Yes you are right!

#3 Updated by pespin about 1 month ago

Hi, which distro version are you using? 201705 or 201705-nightly?

Please make sure your packages are up to date and share your config files.
Also if possible provide osmo-bts-sysmo log files with debug log level, as well as pcap file of the OML and RSL protocols between osmo-bsc and osmo-bts-sysmo.

  • Assignee changed from pespin to eugeneb2008

I just upgraded my sysmobts to today's 201705-nightly and everything is working fine. OML setup is successful, MS can register to the network and both CS (SSD) and PS (EDGE) work just fine.

Reassigning to @eugeneb2008 for further feedback.

#5 Updated by fixeria about 1 month ago

Please make sure your packages are up to date and share your config files.

I guess there might be some change in osmo-bsc breaking backwards compatibility with older pre-FSM code in osmo-bts?

I'm using version: 201310

#7 Updated by eugeneb2008 about 1 month ago

With version tag:1.6.1 all work correctly.

#8 Updated by pespin about 1 month ago

201310 is ancient, I doubt you should be using that. we don't support it anymore. You should consider switching to 201705(-testing,-nightly).

Ok.
Would you prompt a document describing this procedure?
