TCP connect but Radio Calibration required?

QGroundControl
1

Hi, Just getting back into QGC after an absence, so apols for newb questions. Running V5.0.6 on Steamdeck. ArduRover v4.6 all working fine.

Im connecting to the Flight Controller via TCP which is working fine but the vehicle setup is unhappy (red) with the radio not being calibrated. No RC radio apart from the Wifi repeater so im struggling a bit. How to configure QGC with only TCP connectivity to the flight controller

This appears to be a problem as Flight Mode configuration requires Radio setup to be completed prior.

Any pointers appreciated - cheers

My understanding is, the system in general needs that you have done a radio calibration in order to have a baseline as reference.
Once that is done you can disable radio failsafe and operate without any RC.

  • I had similar issues with a slow moving rover setup, which is intended to be used without an RC.

Anyone - this is now a showstopper for me.
Rover is now up and running with Wifi comms (massive range) but QGC is asking for a radio to be plugged in. Hoping not to dig through the old RC box to satisfy a flag.

AI suggested - but it seems a bit untrustworthy.

Option 3: **Use MAVProxy or Mission Planner to Bypass

Use Mission Planner or MAVProxy on a connected PC or the Steam Deck (with Wine or via Linux):

  1. Connect via MAVLink.
  2. Open Full Parameter List.
  3. Search: RC1_MIN, RC1_MAX, etc.
  4. Set reasonable default values (1000, 1500, 2000).
  5. Manually set RC_MAP_THROTTLE, RC_MAP_STEERING, etc. to 0 to unmap them.
  6. Write parameters.
  7. Reboot the flight controller.

This tells ArduPilot and QGC that RC input is not expected and calibration is not necessary.

Regardless the steamdeck joystick moves the calibration of the Throttle, but the NEXT button stays grey.

Any thoughts or pointers appreciated, before i go find me an old RC transmitter …

It is possible to set RC related values manually and in doing so tricking the system into taking it, as if a RC calibration has been done.
The risky part with that is, your vehicle may become uncontrollable if any incorrect values are set.

Best compromise: Ask someone on this forum to provide you with a copy of their setup file. - Needs to be a similar type of vehicle.
Then copy all RC related values to yours.

Thanks - im up and running i set an ardupilot parameter RC_something to 0 and it seemed to work. QGC still needs clearing the errors everytime i connect, im away from the machinery so not much to quote, but we’re rolling.

As more vehicles move to TCP or Mavlink only access - this issue will be more prevalent, so hoping to set a flag on QGC - no radio or similar.

I note also for ROVERS a full calibration of the joystick is required Ailerons Elevators Throttle Rudder, which is a couple of more channels than needed, luckily i have two joysticks available.

I really like the QGC interface - nice work - for ardupilot mission planner has more tools and is native, but for “flights” and mission planning QGC for the win. Thanks team.
