I am trying to connect to my Raspberry Pi Zero via serial Bluetooth. When I try to pair with my Windows 10 PC all I get is an audio connection to the Pi. How do I make a serial connection to the Pi via Bluetooth?

I tried making the Pi Zero 'Discoverable' and then searched for it on my PC. I used 'Add device' in the Bluetooth menu of the PC. The Raspberry Pi Zero showed up, however it was shown as an 'Audio' device.I have seen several posts where the Pi is used to read data from a sensor so it must be possible.

I am trying to create a 'headless' Raspberry Pi Zero W that I can connect to and control via Bluetooth.

  • You didn't explain exactly what you tried, so it's very difficult to help. There's a Q&A here that might help, but it's fairly old now.

  • I believe that I have to setup a 'virtual' serial com port which is linked to the the bluetooth MAC address. But I don't know how to do that. I have the MAC address of the PC that I am trying to connect to. Commented May 19 at 19:15

You will have to write your own Bluetooth stack.

Raspberry Pi OS (your OS is unknown) only supports limited Bluetooth services. This was explained by Steven Long some years ago and AFAIK has not changed.
