    j) W25N01GV 1Gb flash support
  10. Bug fixes
    a) Accel calibration throws away queued commands from GCS (avoids commands being run long after they were sent)
    b) Airmode throttle mix at zero throttle fix
    c) Cygbot proximity sensor fix to support different orientations (see PRXx_ORIENT)
    d) Loiter fix to avoid potential wobble on 2nd takeoff (was not clearing non-zero attitude target from previous landing)
    e) Lutan EFI message flood reduced
    f) Missions download to GCS corruption avoided by checking serial buffer has space
    g) Payload place fix so vehicle flies to specified Lat,Lon (if provided). Previously it could get stuck
    h) Safety switch disabled if IOMCU is disabled (see BRD_IO_ENABLE=0)
    i) Script restart memory leak fixed
    j) Takeoff vertical velocity limits enforced correctly even if PILOT_TKOFF_ALT set to a significant height
  11. Developer items
    a) Custom controller support
    b) Fast loop task list available in real-time using @SYS/tasks.txt
    c) Parameter defaults sent to GCS with param FTP and recorded in onboard logs
    d) ROS+ArduPilot environment installation script
    e) Sim on Hardware allows simulator to run on autopilot (good for exhibitions)
    f) Timer info available in real-time using @SYS/timers.txt

While we think this beta is safe (many developers have been flying it), this is the first beta release of 4.3.0 so it includes a lot of changes and certainly the chance of issues is much higher than with other beta releases so please be careful and be ready to re-take control in a more manual mode like Stabilize or AltHold.

We are very much looking forward to any and all feedback on this new major release and we will be answering and investigating all reports.

Thanks to all the developers who contributed to this release!

Will gimbal roll control for missions and GCS commands be removed in the future?
I want to keep using gimbal roll control in missions.

Copter working well in stabilized, loiter and auto. Successful tests using the ellipsoid altitude. One question regarding the setup for GPS altitude navigation, together with the new EK3_GPS_VACC_MAX setting. Is the correct set-up to follow “Using GPS for Altitude Sensing — Plane documentation” and also use the new EK3_GPS_VACC_MAX setting? This way i understand that if GPS fails/is lost, then the barometer takes over, even though all EK3_SRC"X"_POSZ are set to GPS?
Thanks for the new update!

@horiuchi4dn,

Thanks for getting involved with Beta testing.

Yes, controlling the gimbal’s roll is still supported using the DO_MOUNT_CONTROL command. We won’t remove support for this before we provide an alternative.

Hi @Magnus,

Yes, I think your understanding is correct. The Using GPS for Altitude Sensing looks correct to me for Copter as well although the last step, “Set AHRS_GPS_USE to 2” is not necessary but also does not harm for Copter.

@vishal2248,

I’ve never used this particular flight controller but in general you can change what each serial port is used for by setting SERIALx_PROTOCOL.

I might ask @andyp1per to help you out with the RCOutput issue although it’s not clear to me exactly what problem you’re seeing. Are you saying that the LEDs on the ESCs are not working? … or is it the LEDs on the autopilot or maybe the GPS that are not working?

EDIT: ah, you’re trying to setup Neopixels but can’t get them to work?

LEDs on the ESCs 1-2 are not working

@vishal2248,

OK, thanks for the clarification. I’ve added this to the issues list for “requiring investigation” as well.

I think we covered this in a different thread - PWM1,2 & 9 are all on the same timer so all need to share the same protocol

Flying with a Pixhawk-2M with Stab, Alt, PosHold, Loiter mode. No issues. Thanks for the great work.

Thanks for the work put in just want to clarify support for the Mamba F405 mk4 included the mini 20 x 20 version?

Yes it does - it least that is the version I have. I think there might be an updated version with a different IMU that I don’t yet have

Thanks,
This is the one I want to get just want to be sure its supported.

About EK3_GPS_VACC_MAX there is ek3_src_alt to set to 3 ? Or is it automatic?

Even if set to 1 baro, if gps vacc is below max thershold, ek3 use gps alt instead of baro?

Can someone detail what this means and how it locks arming?
