what kind of SDCCH have you tried? SDCCH/4 or SDCCH/8?

My testing has shown that they are present for SDCCH/8 but missing for SDCCH/4.

I have pushed a fix for the bug I have observed to https://gerrit.osmocom.org/6871

Please comment on whether this fixes your issues, too, or if you experience missing measurement reports beyond SDCCH/4.

Actually, I was wrong. The problem affected both SDCCH/4 and SDCCH/8.

I don't understand how those old/existing fn102 were computed and how they have been verified. At least with osmo-bts-trx, my patches are required to make measurement reports work. This must be double-checked with other BTS types.

dexter: Do you have any idea how you verified measurement reports for SDCCH/4 and SDCCH/8 at the time?

related patch has been merged to master.

Please verify measurement reports now are present formall channel types on sysmo/octphy

Looks good on sysmoBTS 1002 (with nightly build)
I am seeing meas for SDCCH and TCH
:)

The patch in question dates back to code that had had been contributed by Octasic inc. I have checked the code against the specification. Since I managed to find the numeric values 11 and 36 in 3GPP TS 45.008 the implementation looked plausible to me. However, I had difficulties to understand the offsets in the code and I still have them (even with the corrected version).

I did tests for the traffic channels only (see OS#2329). The signaling channels slipped through.
