I'm hoping to use the Raspberry Pi as a Bluetooth microphone for an android device. The basic idea is to feed audio from a USB microphone to the Raspberry pi, remove background noise, and then send that filtered audio to an android device over Bluetooth. I have a filtering ML model successfully running in Python but I can't seem to find a Python module that can be used to send Bluetooth information. Furthermore, I have only seen posts discussing sending audio to a Bluetooth speaker, not an android phone. Any resources on how to get started on something like this would be greatly appreciated.
