I have an audio recorder which needs to be monitored AND remote controlled.
I use a BC-127 module in the recorder as a2dp source… but since Android phones don’t seem to be able to act as a2dp sink, I need a small BT audio receiver for audio and that works fine.
My issue is that the accompanying avrcp protocol doesn’t offer enough possibilities as a remote and I’d like to use SPP (or whatever else) from my phone.
Can I make a new connection - perhaps in BLE mode - when the BC-127 has already a classic link with another device? And if not, could you imagine another way to solve my problem?
