Optical Flow doesn't work on 1.16.x (latest)

PX4 Autopilot
1
  • MTF-01 working on 1.14.3, hardware is OK
  • MAVLink Inspector got DISTANCE_SENSOR and OPTICAL_FLOW_RAD, software configuration seems good to go.

And I switched stablized mode to position mode, it worked for a couple of seconds when flying, then it switched to altitude mode.

I’m NOT sure what’s wrong or what parameter should I configure.

Any help is well appreciated here.

We have followed guides here:

  1. MTF-01 Guide
  2. MTF-01 Optical Flow&Range Sensor

Any idea?

1.14.3 works fine, 1.16.0 rc version is NOT working.

4

1.15.4 works fine. Any one knows why it didn’t work on latest master branch ?

Any update on this?

Also having the same issue, using the same MTF-01 sensor and Pixhawk 6C Mini. On 1.16 it switches from Pos to Alt ~6s after arming, both in the air and on the ground. On 1.15.4 it works fine.
