Hey everyone! I’m having an issue with my NxtPX4 V2 drone running PX4 firmware where takeoff and mission mode don’t work when controlled via QGC. The drone arms and transitions to Mission mode, but it doesn’t move—nothing happens beyond that (the inactivity disarm happens after 30 s). I can operate my drone perfectly via Radio/RC control. I have the MicoAir MTF-01, a GPS/mag module, and a wifi module connected to the flight controller. The logs consistently show mission commands being sent and received, just nothing occuring in real life apart from arming:
INFO [commander] Armed by external command
INFO [navigator] Executing Mission
INFO [navigator] Climb to 4.6 meters above home
INFO [logger] Start file log (type: full)
INFO [logger] [logger] /fs/microsd/log/2025-07-07/02_52_01.ulg
INFO [logger] Opened full log file: /fs/microsd/log/2025-07-07/02_52_01.ulg
INFO [commander] Disarmed by external command
INFO [logger] closed logfile, bytes written: 813082
What’s the PX4 version and can you upload a log to logs.px4.io and share it here?
Hey! Here are a couple:
I want to make clear the fact that the drone is operational in position mode with rc, but from QGC it can only arm/disarm (the mission/autonomous flight modes don’t work, even though there seems to be commands that are sent). Please let me know if you see anything. Thank you!
Thanks for the logs. This also answers my PX4 version question.
It looks like you’re flying with a commit from main about a year ago (ekf2: mag control reset filtered test ratio on start (if aligning yaw) · PX4/PX4-Autopilot@30ce560 · GitHub).
You generally have the choice between main or release candidates of the next release (1.16) for early testing, or latest stable, e.g. 1.15.4. For anything in-between, your bets are off, as it’s probably anywhere mid-development.
I would suggest to try again with the release candidate 1.16 and check whether the issue still exists. If it does, then that’s a valuable bug report that likely would have to be fixed for the release.
