:thinking: General Discussions

I would like to discuss ModalAI PRs 21426, 21427, 21428, 21434, 21435, 21436, 21437, 21472, 21474, and 21477.

I would like to discuss implementation of a platform independent UART API. Here’s a first cut with a working platform implementation on Qurt platform: Comparing voxl-dev..uart_interface_experiments · modalai/px4-firmware · GitHub

Can we also discuss MC_Pos_Control: takeoff bug constrain hover_thrust_estimate by hendjoshsr71 · Pull Request #21380 · PX4/PX4-Autopilot · GitHub? I think we may have just seen this on 1.13 and had the drone go full speed into the ceiling!

Hi, I have a question about VIO. Is there any example of the VIO bridge ROS node that provides a bridge between a camera and ROS? If yes for what version of firmware is it compatible with? Previously I was trying to use Autherion VIO bridge but it is not available now – (github page is not found). Do you know if Autherion would modify it’s VIO bridge?Question about VIO bridge- If I am working with EKF2 camera data should be streamed to /mavros/odometry/out or /mavrosvision_pose/pose?

Second case, what are the appropriate mask settings for the ekf2_ev_ctrl to fly drone with VIO and missing temporary GPS.

I have a quick question, I’ve been having the PARAM_VALUE mavlink message poping up in the Iridium mode on an interface. But I’m not able to replicate that consistently.

I was wondering what could be generating PARAM_VALUE messages being sent on the Iridium interface?
