I find that I cannot connect to the PID screen using XBees. This used to work before.
However, I can see the Sensor/Radio-in/Motors-out screens using Xbee. GCS also connects fine.
When I try the PID config screen, it says something about an ID mismatch and "Port in use?".
So, to summarize:
I can't get the PID config screen to work with XBee.
Sensor output, Radio-in, GCS work fine using Xbee.
Everything works with USB.
Any pointers as to what I could be doing wrong?
p.s. since the Sensor view and radio view works, I assume the xbee config (port, speed) is OK.
I also tried reloading code and resetting EEPROM, but the problem persists.
