Hi zecke and others,
I may have found a cause of one of the problems that we've been
experiencing in nanoBTS bring-up, at least at some point in the past.
The problem could be observed/described as: During the first OML
connect of the nanoBTS, OpenBSC fails to bring it up completely. Second
and successive connects worked fine.
What I have just noticed is that we never re-set the NM state
information for the 12.21 MOs inside OpenBSC. This means, if the A-bis
link is lost, the old state information continues to exist.
I guess it would be cleaner to simply re-set all the nm_state strucures
that are part of the 'struct gsm_bts', gsm_bts_trx, etc. when the A-bis
link is lost.
As I'm working in this area right now anyway, I intend to produce a
patch addressing the issue.
But now that I think more about it: I guess it is unrelated to the old
problem, as a typical work-around was to re-start OpenBSC, at which time
all state is re-set again.
Regards,
Harald
