Gopro 9 Remote Control using Bluetooth (BLE)

I Allready made a first datafield for connecting a Gopro over BLE, see my datafield
Finding the gopro and pair request seems to succeed because the status is connected
However sending a command fails (no error in connectIQ!), the gopro just ignores the command

I think that after a pair request and sending the first command the gopro sends an pair request back and must be accepted on de garmin
This is tested on an iPhone

Pairing the gopro in de settings of the firmware of a VA3M is not possible because the Gopro is not a sensor, I would like to do the pairing there instead

Some one?
