I would like to use the raspberry pi as a bluetooth microphone for my iphone. Not the speaker, ONLY the microphone. My vision is to have a microphone plugged into the raspberry pi that could connect using bluetooth to my phone. I do this because I need a way to connect my phone to a microphone without using the headphone jack (more details here). Is this possible? I don't want to have to buy a bluetooth microphone if it is not necessary.
