H-Flow Sensor Issues

Hello, I recently tried to set up my H-Flow module with a pixhawk 6C mini model A. I’m currently on FW 1.15+ (stable release).

I set up my H-flow as per the set-up guide over CAN bus 1 and can see accurate distance measurements in the mavlink inspector… I can also do an altitude assist hover. Although there is no optical flow data when I am connected via a telemetry radio.

It gets weird bc when I plug in hardwire from computer to pixhawk the optical_flow_rad suddenly populates and I get flow data.

This made me think it was a hardware issue so i powered the H-flow with 5V from the PDB… Still no data.

Can Anyone help ??? Am i on the wrong firmware ? Has anyone got a module to work fully in a hold ?
