Problems connecting V5 telemetry to Pixhawk 2.4.8 (PX4 v1.16 + latest QGroundControl)

Message:
Hello everyone,

I’m currently using a Pixhawk 2.4.8 flight controller running PX4 v1.16 firmware and a V5 telemetry module.
I’m also using the latest version of QGroundControl.

When I connect the telemetry module to the Pixhawk and try to communicate through QGroundControl, I get the following messages:

  • “Vehicle 1 didn’t respond to request for parameters. This will cause QGC to be unable to display its full user interface.”
  • “Parameters are missing from firmware. You may be running a version of firmware which is not fully supported or your firmware has a bug in it.”

The telemetry modules are configured correctly (same NetID, baud rate 57600, air rate 64), and their LEDs show a proper link between them.
However, parameter download from the Pixhawk never completes — the progress bar stops around 50%, and QGroundControl cannot access or display the full parameter list.

I have already tried reinstalling the PX4 firmware, changing USB cables and COM ports, and reinstalling QGroundControl, but the problem persists.

Has anyone experienced this issue before, or could there be a compatibility problem between PX4 v1.16, Pixhawk 2.4.8, and V5 telemetry modules?

Any help or suggestions would be greatly appreciated.

Thanks in advance,
— Mehmet

Trying setting MAV_0_MODE (or whatever instance you have the radio on) to “Low bandwidth”

Previously, the parameter download in QGroundControl was stuck at around 50%.
I tried changing the MAV_0_MODE parameter to Low bandwidth as suggested in the forum,
but now there is no parameter flow at all — QGC doesn’t seem to receive any parameters from the Pixhawk anymore.
The telemetry link is active, but the system doesn’t respond.

I have the same problem. Have you find a solution for this?
