I’m in the process of setting up my new Matek H743-Wing and am experiencing a crash when connecting to Bluetooth in Mission Planner.
Here is my setup/testing:
- TBS Crossfire Nano receiver connected to Matek H743-Wing on UART7 (telem1/serial1). Note that this is the only connection from the receiver to the FC (aside from power and ground, of course).
- Receiver set that the only two channels going to the FC on UART7 are both Mavlink Rx and Tx channels.
- “RC by Mavlink” turned on on the receiver.
- When connected to the FC in Mission Planner over USB, I see RC input from the transmitter, so I know the Mavlink connection is working.
Problem: When I attempt to connect to Bluetooth on COM5 Standard Bluetooth over serial (at 57600 baud), I get “Mavlink connecting”, which will almost always just freeze Mission Planner, rendering it unresponsive. Even if I leave it for a while:
Very occasionally, Mission Planner won’t freeze and I will instead get a “Connect Failed” with the following details:
I believe this issue is specific to Mission Planner. If I instead open up QGroundControl, I can connect over Bluetooth and QGroundControl updates as I move the flight controller around:
Any thoughts or ideas?
Thanks in advance,
