Can't find EKF2_AID_MASK in PX4 v1.15.4

Hi,
I’m using PX4 v1.15.4 (stable) and I can’t find the parameter EKF2_AID_MASK in QGroundControl

I’m tryping to give vision feed to my pixhawk 6c mini via telem 2 port,

I’m using an external camera with range finder and trying to implement optical flow. The external camera is connected to raspberry and raspberry pi performs the optical flow algorithms.

Where did you see information about this param? I can’t find it in the reference: Parameter Reference | PX4 Guide (v1.15)

Seen these docs?

The EKF2_AID_MASK parameter existed in earlier PX4 versions (e.g., v1.12) and was used to configure sensor fusion inputs like GPS, optical flow, and vision.

I can’t find this parameter in v1.15.4 or the current documentation, so I’m trying to understand if it has been removed, renamed, or replaced by a different configuration method.

My setup:

  • Realsense D435i → Raspberry Pi 5
  • Raspberry Pi 5 ↔ Pixhawk 6c mini [PX4 v1.15.4(stable) via UART (TELEM2)]

I’d appreciate guidance on how to:

  1. Feed vision pose (e.g. VIO or odometry) into PX4 over UART
  2. Configure PX4 v1.15.4 to fuse this external vision data

That parameter was removed on 1.15
It has been replaced by the EKF2_***_CTRL parameters

Like EKF2_EV_CTRL
