Feature Request: redirect bluetooth mic input to bluetooth speakers output

[david-shiko]

The Case:

When I'm wearing a motorcycle helmet, my voice is hard to hear during a conversation.
but there is a Bluetooth headset microphone in the helmet, and Bluetooth speakers on the motorcycle, so I came up with the following scheme:

1. Press the Google assistant call button, say the command.
2. The command will open my androidMic and trigger a deep link / intent / active action, i.e. activation by opening the application.
3. Input, the bluetooth headset microphone will be used as input, and the speakers as output.
4. It will be active while I'm talking, voice recognition.
   According to the idea, this repository is suitable, I even found Bluetooth mode in the code.

Both my devices are bluetooth 5.0 and smartphone redmi note 12s, i.e. supports multiple bluetooth devices.

I'm a backend developer and may do PR but I have too few experience with mobile and bluetooth tech details.

From what I understand so far and what I have gooled:
2. Bluetooth Profile Management:

• Force headset to stay in HSP/HFP mode (microphone only)
• Route all audio output to bike speakers (A2DP mode)
• Prevent automatic profile switching

3. Automatic Session Handling:
   • Maintain connection while speaking (voice activity detection)
   • Auto-disconnect after N seconds of silence

Hi thanks for submitting your idea!

From what I understand, you want your helmet headset as microphone to your phone, and bike speaker as output speaker. So that for example you can have a better quality phone call when you are on the bike. I can see the value of such use case. However it's beyond the scope of this project. This project is intended for people to use their android phone as microphone input to their computers.
