Description

Starting from revision 8c1d15764377eb6a11aa432661d5afe60c2e8a9c CalypsoBTS-based transceivers (I tested jolly/testing) does not longer work.

osmo-bts-trx fails early with:

<000b> trx_if.c:488 Response message 'RSP SETSLOT 0 5' does not match command message 'CMD SETSLOT 0 5'
<0001> bts.c:210 Shutting down BTS 0, Reason TRX-CTRL-MSG: CRITICAL

I added some log statements to the beginning of the cmd_matches_rsp function and the output from osmo-bts-trx now looks like this:

SETPOWER does not match SETSLOT so cmd_matches_rsp returns false.

Full logs, configs and a pcap trace is attached.

On my sysmocell5k or while using limsdr with osmo-trx, I get the following responses:

As you can see, RSP SETSLOT has an extra value in relation to calypsoBTS rsp.

README in osmo-trx says:

SETSLOT sets the format of the uplink timeslots in the ARFCN.
The <timeslot> indicates the timeslot of interest.
The <chantype> indicates the type of channel that occupies the timeslot.
A chantype of zero indicates the timeslot is off.
CMD SETSLOT <timeslot> <chantype>
RSP SETSLOT <status> <timeslot> <chantype>

Which means CalypsoBTS RSP SETSLOT is either missing either status or timeslot in the response, probably the status is missing. I'll have a look and submit a patch for it.

Please test the following patch and provide feedback: https://gerrit.osmocom.org/#/c/6449

#4 Updated by roox 5 days ago

I just did some tests - It works like a charm - Thanks!
It's probably also a good idea to include this patch in the other branches with transceiver support (e.g. sylvain/testing)

#5 Updated by pespin 4 days ago

  • Assignee changed from roox to pespin

I backported the patch as indicated.

So we now have the patches reviewed (+2) but due to the branch being old and having no jenkins.sh, Jenkins Builder set validate -1, and I'm not able to merge it. Help on how to fight against gerrit is required here.
Patches are:

I could manually override the V-1 and set it to V+1.

However, I guess the better solution would be to first merge a patch
that adds jenkins.sh to the respective branch, and then re-trigger the
validation of those patches. This way we would have a working solution
even for future patches.

Or even better: Rebas those old but still relevant branches on top of
current master, and they would get the jenkins.sh and associated build
verification for free.

Do we have any volunteers for this?
