I am having some difficulties setting up telemetry for an UAV and hope to start this post to pool some ideas.
i am using APM2 with the latest firmware ArduPlane V2.50 uploaded to APM2 using mission planner 1.2.4 mav 1.0
on the APM2 side i uses the xtremebee board
function set: ZIGBEE ROUTER AT
on the PC side i uses the xtremebee USB adapter
function set: ZIGBEE COORDINATOR AT
both xbee are XBee PRO S2B
they uses the same PAN ID and share the same baud rate 57600
i also tried different baud rate and different digit of PAN ID which do not matter as long as they are the same in both board. (except 38400 does not communicate)
having matched the SH DH SL and DL i am able to establish a clear communication between the two in X-CTU. it passes the loopback test with 100% and able to return what i type in the terminal tab.
when i try to move on to the mission planner i am unable to get a connection even with the same baud rate and correct COM port number. i get an error saying "no heatbeat packets received" after the 30 second timeout. yet, over on the terminal tab in mission planer i can use "+++" and "atnd" to detect my xbee on the APM2. and this is done with the APM2 powered with an external battery and xbee on the PC connected via a USB cable.
i am wondering if anyone is able to show me the rope?
