Does Bluetooth pairing guarantee microphone access in an app?
No. Pairing establishes a device relationship, while microphone access depends on the supported audio path, application interface and permissions. An app can see the glasses without being able to capture their microphone.
Confirm which microphone supplies the input
Identify whether the app is receiving audio from the phone, the frame or another connected device. Otherwise a successful transcript may be attributed to the glasses when the phone actually captured it. This matters especially during a prototype tested with several devices nearby.
A controlled trial uses the documented input selection and makes the active source clear in the app. If display commands work but capture does not, investigate the audio interface separately. A functioning custom data connection is not evidence that a microphone stream is exposed through that same connection.
