I am looking for solution to bluetooth audio transmitting task. Features needed in BT audio transmitter:
- maintain BT connection with BT headset
- receive audio input from external source (3.5 mm input)
- transmit audio via BT only if input audio level is higher than some threshold
Currently used BT audio transmitter CSR8675 based, similar to
Recepteur-Bluetooth-5-0-CSR8675-Adaptateur-USB-audio-de-musique-sans-fil) is
too keen to transmit - it is always transmitting audio, even when audio input is silent or missing.
Slightly different BT audio transmitting principle is needed (used with smart phones) - that is, transmitter should maintain BT connection, but stream audio only when audio source is present (music player is on or call is in progress).
Can you suggest a better solution (preferably something off the shelf)?
