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 Randy, rc7 flew fine, tested most situations with no problems thank you. Having trouble tuning out glitches/wobbles during forward flight. Can you tell me while flying downwind, the quad is as smooth as silk, but when I turn and fly into wind it had wobbles and glitches everywhere. Have you seen this happening before? The pixhawk is out in the open, am I getting airflow disturbance over the sensors?

I've checked both the lastest Beta and the latest official MP and I'm seeing PosHold. Beware that if you install from .msi that it'll be an older version that's installed. Best to push the Help, "Check for Updates" button after installing from the .msi.
Forgot to attach my log. Here it is:

I've had a bit more of a play with my micro 250 copter running 3.2-rc6 and have a couple of questions.
1. It seems to fly fine in stabilize and Alt Hold but when I switch to Loiter the motors sound odd and it's a bit jumpy. I looked at the logs and you can see this on RC Out 1-4 when I switch to Loiter mode. Is there something I can do to improve that?
2. When I arm the copter Mission Planner displays two errors, 'Bad Flash' and 'No Terrain Data'. I haven't seen these before.
3. If I try the Auto Log analysis in Mission Planner with any data flash log I get the following errors:
'Test Underpowered' object has no attribute 'enable' followed by 'Bad Input File'.
Darrel,
#1. looks like you have the EKF on. Could you try turning that off to see if it helps? There's a known issue about jumpiness with the EKF. We have a fix coming but it's not out yet.
#2, the "Bad Flash" is not something I've seen before and worries me a bit. Maybe it's related to this issue though which is just a reporting error. The "No Terrain Data" is very common especially before the vehicle gets GPS lock. We don't use the Terrain data in copter yet (except for display purposes) so maybe we can ask MichaelO to suppress that message for now.
#3 is definitely a bug in MP that's been fixed in the latest Beta so as soon as the next official MP release goes out that'll be resolved. By the way, it's also possible to upload the log files to DroneShare and have it do the auto analysis. I've never done it myself but apparently it works.
I turned the EKF off and the loiter on my micro 250 quad is working quite well now. I've added a camera and larger battery so it's flying a bit 'soft' but I'm sure another go with the auto tune will take care of that. I tried that yesterday but there was a bit too much wind so I'll try again today. Regardless, the micro is flying just fine with RC7 and I appreciate your help. I hope you have scheduled some time off after the release. Come on down to Australia and I'll shout you a beer.
Some devs are already there...
Thanks for the info. Can't fly today due to high winds but I'll turn off the EKF and go for a test tomorrow. Cheers.
