Can it be used as HC06 and send the serial data?

For BLE Pass-through, can I have my phone connected to the module via Bluetooth and the module passing the audio to a Bluetooth speaker?

How many is the resolution of ADC and DAC?

Hi everyone,

I'm using a DFR0781 Bluetooth module for one of my audio projects. It's a nice module, but I faced to one issue while developing my project.
I use a special custom APP with BLE connection that needs a special UUID(128bit).
Definitely this module has FFF0(16bit) as the service UUID.
Generally this 16‑bit UUID users can set it by themselves.
But If I need a special 128bit UUID, I need to contact Qingyue Electronics to customize and modify the underlying settings of the module.
Could you please tell me how to contact them?

Thanks!
