for a new copter setup I’m trieing to setup a telemetry between copter and Mission Planner using two XBee 3 Pro radios. The radio for the GCS is mounted on a Sparkfun Explorer USB adapter. The radio on the copter is mounted on a Sparkfun Explorer regulated board and connected to telemetry port 2.
I have programmed the two radios in the Digi XCTU software to communicate with each other in transparent mode. I have tried the communication between the two radios in XCTU and all works fine. When I connect the copter radio to the copter and try to connect through mission planner, the timeout counts down and finaly shows an error message “No Heartbeat Packets Received”. I have already tried to change RX and TX lines but no success.
It might be still a problem with the programming of the radios although they communicate in XCTU.
Does anybody have experience with the XBee 3 Pro radios and knows how to program them to use them as telemetry radios?
Is it possible that the hardware is not compatible? I think I have read somewhere that there might be a problem with pullup resistors and TTL level.
I would be very thankful for any help.
