Here is another thought. Just thinking out loud.
When I used the TomTom bluetooth remote, it did the same thing almost as this setup. But the difference that I was able to do and setup the .kl file to remap all the buttons.
Remapping is very fast, that's what External Keyboard Helper is doing. But I could not get the .kl file working.
If I or you figure it out, the wireless setup -which is still my goal- would be great.
I'll try some other remapping apps that support bluetooth controllers. External Keyboard Helper is not the only one.
I didn't come this far to have a 'simple' obstacle like this come between me and having this project done
