Bluetooth headset and audio routing
The Bluetooth intercom mode is one phone plus a Bluetooth headset, with push-to-talk. It is not a connection between two phones over Bluetooth.
Audio routing:
- The app defaults to the earpiece and can switch to the speaker, a Bluetooth headset, or a wired headset.
- Some manufacturers force speaker output or change routes when a headset connects. Behaviour can differ between devices.
- If audio goes to the wrong device, check the system output and reconnect the headset before reporting a fault.
Not every headset or phone model has been verified for this mode.
