flowiq2200 - No C1 frames

[anhorbc]

Trying to capture data with the flowiq2200 driver. I am not seeing a single C1 frame. CC1101 is 10cm from the water meter. I can only see a bunch of T1 A frames. Using a 868Mhz cc1101 module, that previously successfully captured frames from the same meter (using different code). I am able to successfully capture C1 telegrams from the meter with rtlsdr + wmbusmeters. Not sure how to troubleshoot this further? I have tried switching mode between T1C1 to C1 and back, tried both decimal and hexadecimal meter id.

Turned out to be a grounding issue. After properly grounding the cc1101 module, it is working as expected.
