I am using APM1 with Xbee pro 900 stock.
When I am updating params for Arducopter, I got failure and then it could not connect any more.
The Mission Planner is 1.1.31.
Is there any way to test this Xbee and detect what module is wrong? Both them still have power on.
Ps: This is the screenshot of this error from Mission Planner
One of the modules is probably bricked, follow these instructions from the wik http://code.google.com/p/arducopter/wiki/APM1telemetry
Unbricking an Xbee
IMPORTANT NOTE: Sometimes Xbee modules get corrupted due to spurious signals. If you're finding that yours stops working (green LED on Adafruit adapter doesn't come on), instructions to reload the firmware follow:
