Community Q&A
- Daniel Nix Is trying to connect 255 drones to MAVSDK. He managed to have 100 simultaneous connections on a prototype setup but then started to run into resource issues. He’ll ping @JulianOes on slack to check since he’s mobile in the call and cannot discuss well at the moment.
Project Updates
-
@vxj9800 Rapberry Pi board support was added. Update: He created an issue on upstream NuttX for the I2C reset that lead to issues. It’s being worked on. He’s designing a flight control board based on the Raspberry Pi MCU and hopes it will be working soon. He’d be happy to disucss with
-
@MaEtUgR Manual control selection and cleanup was finally merged. https://github.com/PX4/PX4-Autopilot/pull/17404
Any feedback welcome. Note: By default only RC receiver stick input is accepted and you need to setCOM_RC_IN_MODE(Parameter Reference | PX4 User Guide) to accept only Joystick or both. This is by design for safety but can be changed if there’s feedback. -
@AlexKlimaj 's UAVCAN GPS is being integrated. There’s an open pr with just a few points open. GPS driver part was merged during the dev call. PX4 repo side needs to be updated now.
UAVCAN F9P Moving Baseline by AlexKlimaj · Pull Request #18412 · PX4/PX4-Autopilot · GitHub -
Thomas Deburnner Added support to run SITL jMAVsim natively on Apple M1 chips. He’ll create a pr for that.
High priority queue
Groom the board! We’ll discuss it in the next dev call.

Release
We’d have enough changes for a new release but the plan is to have the new output configuration and dynamic control allocation (which is currently work in progress) in a state where we can comfortably ask any user to test it. 1.13 is currently planned to be the last release which is planned to use the old mixing system. There is no date defined yet.
In-Depth discussions
- @dagar Further improved the dynamic notch filter sensors/vehicle_angular_velocity: add new parameter for ESC RPM notchfilter BW by dagar · Pull Request #18564 · PX4/PX4-Autopilot · GitHub It was flight tested and the graph shows a significant difference. What effect it has on the possibility to increase the default low pass filter and the rate control gains still needs to be found. It looks promising.
