Hello, I’m using herelink, cube orange, here3 gps, and here+ RTK. Previously all worked fine. now i have problem Qgc App can’t connect with my drone, :
- QGC status : Waiting for vehicle connection
- AirUnit LED1 Off, LED2 Yellow
- Herelink Radio status : Paired and data connected
- Remote can control the drone (sbus)
Steps that have been taken
- Reinstall firmware:
Herelink Remote, (FRU01200409)
Air Unit, (AAU01210729)
Pixhawk (4.0.7 and 4.1.0 all tried)
- reset to default parameters, no use GPS & RTK
- Repairing Remote and Air Unit
Until now QGC can’t connect , Anyone help me please
Have you checked if Telemetry is configured correctly on Flight Controller and that connection is OK ?
In this case I would test with a FTDI - USB to serial converter connected from the PC to the FC and confirming that MavLink is ok looking at Mission Planner.
Thanks for your response. I really appreciate you.
I’ve set the serial parameters like the image. I think it’s ok.
There is something else i have to do?
I generally set protocol to mavlink 2 for herelink communication and the speed is autodetect up to 115 kbps but I had an issue once with speed synchronization with the air unit and I had to reduce to 57 kbps
I don’t know the details of the issues came from. But what I did was re-install the firmware of all devices like when I first bought the herelink and cube packages.
I’ll note your solution when I’m facing the issue again.
thank you @ppoirier
