Found a usability issue while using a the VTOL aiframe and not wanting to transition. It automatically (couldn’t finish)
- Is the DO_SET_SERVO command supported?
The best solution is to use the new control allocation system and the DO_SET_ACTUATOR command. That will work nicely. It is also available during a mission
- Terrain following logic?
Matthias : In a Multicopter, for altitude mode there is a terrain following mode. But for mission,
But there are 2 frames, and mission runs on ‘global’ frame, so need to consider that for accounting for the distance sensor altitude value.
Daniel : QGC Support, ‘frame’ option to take this into account
- Water sensor
Daniel : would feed it to EKF2 terrain estimator, and check output (for this sensor over water use-case), and use it as altitude feedback.
Safy : Current, altitude deviation from sonar sensor was very jumpy.
Daniel : Altitude vs Terrain estimate, they are different.
Mavlink Message “ALTITUDE”, element ‘bottom_clearance’.
Parameter EKF2_TERR_NOISE, EKF2_TERR_GRAD
- Trying to have a new Compass, Holybro IST210.
David : if the address of I2C devices are not interfering with each other, it should be fine.
Daniel : Can use
-son a driver level, to try different addresses (
Fellow : Current re-doing them in console manually everytime.
Daniel : Should create issue & fix code use case for this magnetometer address issue.
- Dual Mag.
V5X GPS2 is I2C2
EXT2 is I2C3
Using Global GPS from Holybro, and using local_gps module, the coordinates are 0,0,0.
After landing, the coordinates aren’t 0,0,0.
Matthias : Local position set when estimator initialized. Global set when GPS estimator initialized?
Coordinates gradually increasing / decreasing.

Daniel : Newer RC protocol called ‘ghost’ issue. Someone’s crossfire scanned & latched onto ghost protocol & self-armed and took off!!!
Matthias : Happend as well, used crossfire receiver back then.
Charles Cross : For non-aerial vehicles, is the current master branch stable enough? Daniel : yes.
