The new heli setup works great!

I’ve noticed with CUAV V5 it doesn’t recognize the board except for PX4. And can’t get it to load a ChibiOS .apj or .hex build. It can only “see” a .bin. So still have to do the build locally here to get the .bin to load it, as only the .apj and .hex are in the ArduPilot firmware downloads.

When I plan and try to upload a mission on my Android tablet I get a warning that the param4 value is invalid.
The value reads ‘–,--’ for all the waypoints. I have to manually change all param4 values to 0 before I can upload. Is there a solution for this ‘problem’?

Best regards,

I’m working on a fix. Should be available in a few days.

Is this with latest daily that supports flashing ChibiOS onto PX4 style boards?

If any folks here ahve the ability to build there own QGC and do testing, the pull is here:

Hi Don,
No, I was just testing the latest stable release to see if it supported yet or not.

(DonLakeFlyer) #8

ChibiOS will only be in daily. Too large of a change for Stable.

Important Update: There is a bug in QGC 3.4 which can cause the altitudes in mission items to sent to the vehicle as 0 when the ui still shows a good value. The easiest way to reproduce this is to:

  • Add the first Takeoff item to a mission
  • Change the Takeoff item to a Waypoint
  • Add a new waypoint item

All subsequently added waypoint items will show in the UI with a reasonable altitude but will be sent to the vehicle as 0 height which can cause a crash.

Standard mission creation where you add the first item which is added as a Takeoff (leave it as Takeoff) and then add subsequent waypoints is working fine.

Issue details are here: A new 3.4.2 which fixes this will be available in a few hours.

QGC Stable 3.4.2 has been released which fixes the waypoint altitude bug.
