How to play sound through hc-06?

Question

Arduino

For the project, you need to play sound on this module. There is an amplifier with and I would like to understand whether it is possible to directly bind the amplifier to the module, or pass it through an arduino?

Answer 1

For this module - no way, this module is a serial port, not an audio codec.
You need something like this

Answer 2

Digitize the data using the ADC, transmit via UART to the HC 06 module (it seems that it can only receive), on the other side, catch the data with the HC module, read the UART, and play the sound using the digital-to-analog converter. But there are a lot of difficulties for me, the transfer rate of HC modules must be taken into account, the time to process the ADC results and send them via UART, etc. In general, it is easier to take a ready-made solution.
