Warning #1: PX4/Pixhawk users upgrading from AC3.1.5 (or earlier) may need to re-do their compass and accelerometer calibration because AC3.2 also uses the backup compass and accels. Pre-arm checks have been added to ensure this has been done.
Warning #2: on the APM2.x the logs must be downloaded using MAVlink instead of the terminal.
AC3.2-rc14 is now available for BetaTesters through the mission planner’s Beta Firmwares link. The full release notes can be found in ReleaseNotes.txt and changes from -rc13 can be seen below.
Feel free to raise issues found during testing on this discussion or in the new support section in the APM Forum.
It’s a big release with “the onion” restructure and a bunch of new features (including these 57 closed items) so we need to re-test almost everything including all flight modes, all mission commands and all the new features. Marco and I will be maintaining (and adding to) this testing list. Issues reported will first be checked by Jonathan, Marco and I and then confirmed bugs/issues will be put on the github issues list (and then hopefully fixed).
Thanks especially to the beta testers who put their copters at risk testing each release. Enjoy!
Changes from 3.2-rc13
1) Safety Features:
a) fail to arm if second gyro calibration fails (can be disabled with ARMING_CHECK)
2) Bug fixes:
a) DCM-check to require one continuous second of bad heading before triggering LAND
b) I2C bug that could lead to Pixhawk freezing up if I2C bus is noisy
c) reset DCM and EKF gyro bias estimates after gyro calibration (DCM heading could drift after takeoff due to sudden change in gyro values)
d) use primary GPS for LED status (instead of always using first GPS)

Hi Paul
I am usually not powering up within magnetic environment. I have to add: But since I use EKF with Ch 8 , my ACC/ Compass calibrations have been done without EKF.
Maybe its better to change this ??
Just noticed, that the effect is still visible (but only a very little bit. difference at 0.2-0.5°) after a few minutes. According to MP the quad lifts its back a little bit, when EKF is turned on. That explains the small movements in flight switching as well.
The last .bin file here http://www.file-upload.net/download-8986981/31.BIN.html
hope this is the right one.
I tried to attach the latest here as well
Thx

Hi Paul,
I did try this on my veranda with GPS 3-D Lock (warm start) and repeated it several times.
I did a HD video
https://www.youtube.com/watch?v=OmSb_gdmkWQ&feature=youtu.be
I am able to arm (which does not make a difference concerning the behavior), but am not sure where I should take the .bin file of. Directly of the sd card or via some MP command ?
It must be pretty short, because it disarms automatically after a few seconds. PH is rev. 2.4 Compass / ACC calibration has been repeated couple of times(for nothing) copter flies nice.
However, I wasn´t worried, because this effect settles down during my usual startup phase (Waiting anyways 3 minutes)
BR
PS: Just tried it with waiting with 15 seconds GPS 3D lock in advance (I did not do it in the video) Behavior is the same.
I just record Hybrid mode test here.
Hi Balloon, nice video. Where is this video taken if i may ask? I will be in Thailand by the end of the year and i would take a quad with me. It would be nice to have to know a place where Thai multicopter pilots meet.
In video taken at Bangkok University Sangsit Campus in Pathum-thani is north form Bangkok.
Thank you Balloon. I see that i can take the train in the direction of Ayutthaya from Bangkok. Hope to see you there. ;)
Yes, i saw is about Barometer have issue it. But, I think we can solve about Baro issue. It maybe have very perfect.
Yes I notice this barometer disturbance issue as well. Maybe fix on RC3?
Finally got enough courage to load the beta on my quad 450 style.
Was very touchy when first starting out in Stabilize mode. Switched to Loiter and tested Hybrid for a minute. Seemed fine. Then landed and switched my mode 2 back to Alt Hold.
Tried doing an Autotune but it got so far and kept stopping, I would move the quad a little and it would do 2 jerks forward and backward and then stop again.
So gave up on autotune. Landed and then took off and was flying around in Alt Hold and it seemed to be pulsing a little when fast forward flight. Was over my neighbors yard and all the sudden it started fluttering and fell out of the sky and landed on his grass.
Logs attached.
Back on the workbench repairing the 3 broken arms. I hope this helps and you can figure out what was the problem. One thing I haven't done is check all my motors and ESC's to make sure one of those didn't fail.

Brad,
A dataflash log would be much better than a tlog. The dataflash logs have much higher rates.
