Hi Joseph,

that sounds bit strange, I've never had this problem before...
What mode are you running the XBee in?
Do you maybe have xbee_api mode configured in your airframe file and are sending some wrong XBEE_INIT codes?

Cheers, Felix

I found a solution.

in v5.0 I modified paparazzi/sw/airborne/firmware/fixedwing/main_ap.c

after line 227 #if defined DATALINK I added:

It works although I'm not sure it's the best fix.

Hi Guys,

I have been having some trouble with my xbee. It bricks every time I power up the board, but works fine if I power up the board first and then connect the xbee. It might be some sort of signal before power issue.

I am not very familiar with C. How should I got about adding a delay of 1 second before sending a signal through the xbee? Would sleep(1000) at the beginning of telemetry.c do the trick?
