ArduCopter-3.2 beta testing

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)

  • Excuse my ignorance but what is guided mode exactly? Is that simply a reference to a 'long press' on a touch pad using DP that is essentially a 'go to here' command or is there more to it than that? 

  • I went out and tried APM  3.2 last night on my tricopter. Autotune, Alt hold and Loiter all work.

    I tried guided mode from a android phone but it didnt move, it stayed in loiter. Is there any known issues with this flight mode?

    Thanks for the hard work

    • Paul,

      I have found that when using droidplanner 2.7.7, if you entered loiter on the edit page at the mission final WP, you must go back to the Flightdata screen to change to Guided mode..

      Paul,

      There was a change in AC3.2 so that we now insist that the vehicle is in Guided mode before it starts accepting follow-me (i.e. position) requests.  I believe AndroPilot and DroidPlanner have been updated to handle this although I haven't checked myself.  You're using a recent version of one of these two?

      • Not to hijack this thread but, in the latest Droidplanner i was able to get Follow me to work with out switching to Guided Mode. Once follow me is clicked, the aircraft automatically switched to Guided Mode. i havent been able to get Andropilot to work in Guided Mode/Follow me even when manually switching to Guided Mode. Droid Planner did work pretty good tho but it did have issues with RC7. i am waiting on rain to go away to try again...or i might be building an Ark Soon and using my drone to find animals to board said Ark :P

      • Yes it was the newest version of DroidPlanner 2. I havent set guided up as a flight mode, would i have to? or would selecting guided from the interface be enough?

        Why was this changed? before you kept the copter in loiter, long press the screen at a point on the map and it asks if you want to go to guided mode, wasn't that check enough? 

        Thanks

        Paul

        • Are you talking about guided mode only, or follow me that uses guided mode? They're two seperate things, follow me automates the sending of guided waypoints. With just guided mode only you have to put a guided waypoint down yourself. With follow me mode the android device sends updates to ArduPilot by itself.
