Application is a Bluetooth speaker.
Microchip BM64 will be wired to a SSM3582.
Issue – volume control. What protocol is used on the I2C line for controlling the volume on SSM3582 amplifier? The BM64 supports HFP 1.6, HSP 1.2, A2DP 1.3, SPP 1.2, AVRCP 1.6. Microchip suggest AVRCP for volume control. The SSM3582 data sheet does not mention AVRCP.
Does the SSM3582 support the above protocols?
If not is a micro necessary to convert the output from the BT module to control commands?
