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)
That rc in rc out and baro alt
Frustrating... I'd say it's a Mac pc thing but it's right on the card like that.
Using IRIS+ factory transmitter and receiver 3.2rc14 worked great, I wanted to switch to my DX9 and spektrum satellite receiver. Now the IRIS+ hunts and doesn't hover, I constantly have to change throttle in stability mode. It also begins to climb at about 30% throttle and in Loiter mode it descends in steps until it lands.
I've gone through the calibration wizard a couple of times, I've set CH6,7,8,9 to do nothing. I've reloaded the IRIS+ default parameters.
Any ideas on anything else to try before I revert to using the factory tx/rx?
To answer my own question doing an ESC calibration appears to have resolved the issue, at least in the garage.
The props also now spin on arm which also wasn't working until the ESC calibration.
Several auto flights, stable, alt hold, pos hold, land... no issue. EKF on. Incredibly smooth.
I have a problem that I cannot arm my copter any more.
There are no prearm errors, it just refuses to arm.
I had some problems with a (pitch/roll) gimbal on my 9xr Pro transmiter, that I sorted out - a loose potentiometer.
After fixing it I did the radio calibration and the problem showed up.
I have tried loading some default parameters, with them I could arm, but then I had another problem.
I could disarm the motors (the red light flashing) but the motors would continue to run at slow speed.
If I change the RC3_MIN the motors will stop but I can't arm again, so it seems to me that there is a problem with my parameters, but I not able to sort it out where.
I am attaching the params and logs (on the bench).
Strangely enough, the problem went away this morning.
I tried to arm it and succeeded?!
The only thing that's different from yesterday is that I didn't connect it to MP.
Will 3.2 be beta forever?
About 2 weeks ago it came out of beta.
It is still Beta but in the final phase they are being extra careful before it's the official release
