IFlight BLITZ F745 AIO could not set EKF origin through MAVROS

I have a BLITZ F7 AIO controller, and everything works well,

but I found that I couldn’t set the EKF origin through MAVROS, like in this script,
which works for my KAKUTE H7 MINI controller.

I’m using serial1, proctol mavlink2, 921600 baudrate, roslaunch mavros apm.launch also works.

Thanks

@andyp1per Thank you for your contribution to this board. May I ask for help with this issue.

If mavros is communicating with the board I don’t see how it can anything to do with the type of board
