I have the same problem as this post::
and still have no idea to solve it. have 2 question after read that post:
1.Does the RSSI offset make any difference to the way the CC112x works or does it just affect the value reported as RSSI?
2. Cause I use the Synchronous Serial Mode without the cc1125 to detect sync/preamble,does the AGC help our application, since I just disable the AGC behavior(AGC_CFG1.AGC_SYNC_BEHAVIOUR = 000 (No AGC gain freeze, keep computing /updating RSSI)
