I was experimenting today with my XBee 3 module, I had it plugged into the Sparkfun explorer board and I relocated my breadboard power supply which also swapped over which was 3.3V and which was ground. I didn't realise till I turned on my power supply and nothing happened. I quickly turned it off off and switched the polarity so that 3.3V was going to the correct pin and GND was too.
I had XCTU on with another XBee connected as a controller, and initially it was picking up the XBee I had powered incorrectly and a third XBee. However the incorrectly powered XBee seems to be unfindable by either of the other XBees in API mode.
If I select the incorrectly powered XBee, click on the network button and then scan for other XBee radios I get the error message about can't find local Xbee, remove from list in the right and reinstall. I do this and still can't scan. However I can update settings, even change firmware on the XBee module. Just doesn't seem to want to transmit and receive.
Is it bricked?
