Thanks. Please note that I am also CCing this message to the<br>
Osmocom baseband-development mailing list, because this info<br>
could be helpful for someone else.<br>

<br>
Great. I also was going to implement this, but happy to see<br>
your efforts towards this direction.<br>

Please send your changes for review to <a href="http://gerrit.osmocom.org">gerrit.osmocom.org</a>.<br>
I'll be more than happy to facilitate merging this work to master.<br>

Would be great to see both logs and PCAP traces attached.<br>
I cannot say anything without knowing what is actually<br>
happening on your side,<br>

I am also using B200, but without GPSDO. Probably, your device<br>
has different delays, which causes out of sync with BTS TDMA.<br>
Piotr Krysik was working on this part, and we had an idea to<br>
implement a tool for automatical device calibration...<br>
<br>
But let's look at your logs first.<br>

<br>
Mostly, I am working in the virtual environment - FakeTRX.<br>
Didn't try since 34c3, but it was working.<br>
<br>
