I’m elaborating with using IQ inversion for our P2P downlink to potentially avoid a bit of link interference.
In one end I have a RAK3172 with our custom firmware. In the other end a RAK3172 with RUI and AT communication.
The problem is that on the RUI side, after turning on IQ inversion (
AT+PSEND), it seems I can no longer disable inversion mode.
OK but any receive after this will never return any data.
Sometimes I can reset P2P-mode with
AT+IQINVER=0 and receive will work again but seems flaky.
Example of AT communication when it’s not working:
AT+PRECV=10000 (here I expect to receive data but never do)
+EVT:RXP2P RECEIVE TIMEOUT
Any suggestions or comments on this is appreciated.
