Stopping/Slowing at each Waypoint

[Dan-Moss]

The aircraft slows to 1 m/s at each waypoint, even in a straight line.
Firmware Version 1.9.2 on Black Cube

Param Changes:

NAV_ACC_RAD = 15

I'd expect changing the Cruise and Cruise 90 would allow the aircraft to pass through the waypoints without slowing, similar to the acceptance radius but it seems to not be working?

Others seem to have this issue

Hi @Dan-Moss , this has been improved post 1.9.2 and is fixed by #12505
You can try the Master development branch, feedback is welcomed!

Thanks for replying @bresch , will build and test shortly (i guess there is no instant way to get a px4_fmu-v3_default.px4) . I will close this issue for now then?

You can use QGC to flash the Developer build, which is autobuilt from master.

@mhkabir when reconnecting to update firmware i'm getting:
Found device: PX4 FMU V2
Error: Sync: Send Command: Invalid sync response: 0xfe 0x10
Upgrade cancelled

v3.5.4 Qground, Windows 10, Cube Black, From Firmware 1.9.2 (also tried 1.8.2 to the same effect)
Tried a variety of PC's, Laptops and USB Cables?

@dagar any clues?

[Dan-Moss]

using http://ci.px4.io:8080/blue/organizations/jenkins/PX4_misc%2FFirmware-compile/activity/ i was able to get the build and it behaves correctly visually (Yay :D ) but the log shows:

had to flash 1.9.2 then 1.9.2dev to get it to connect to qground tho (straight 1.9.2dev does not connect)
