Bluetooth helmet setup

[RoddQLD]

Just wondering what is the best way for me to set up the audio on my raspberry pi4 to suit a bluetooth helmet set up (for music, map audio, etc)? My helmet can connect directly to my mobile phone using bluetooth (and I have no problem connecting OpenAuto Pro to the phone via bluetooth).
I'm setting up a screen on my adventure bike and would like to hear GPS directions, music, and take phone calls through my helmet bluetooth system.

I hope that this makes sense.

You could try to connect the bluetooth helmet to the raspberry Pi as output device.
Or you could connect your phone to both the helmet and the raspberry pi, and keep the helmet as the primary output device, and mess around with the call settings to get it to perform as you want. This will be highly dependent on your understanding of what you're doing, and the phone (Android). I have successfully done this using Android phones, the Tasker app and a bluetooth speaker system for my car.
