Testing Feedback on PX4 main with 6XRT Configuration

Hello Hello,

some long time no see!

I recently had the opportunity to test the new PX4 (main) firmware on a 6XRT drone configuration and wanted to share my experiences, observations, and some data from the flights.

Test Setup:

Observations:

The first impression was a really nice stabilized flight which was stable for real. Altitude, Position and Hold mode in addition to return and takeoff modes all we doing as they had to.

Issues & Feedback:

  • The moment connecting with the battery Yaw Estimate Error was appearing.
  • RTK did not switch to and I was having only 3D Lock the whole testing time. Although QGC surveying was complete!
  • Latency was so high such that params took very long time than normal to be received with once in a while QGC errors mentioning Vehicle could not send params fully! (You know which error am talking about)
  • Distance sensor readings are fishy

I replaced my Telem with Holybro btw.

Hi Farhang, On the observation any difference between main and release/1.15 ?
Which FMUM / baseboard has been used? The latest revision with markings or the one u got during PX4 devconf ?
cheers, Gerald

Hey Gerald,
This was the layest main I tested which is ahead of 1.15 I assume. But no difference so far.

The board is the latest one you sent me with markings.

Regards,
Farhang,
