I would like to use the module in “stand-alone” mode: no PC or microcontroller connected to the serial port.
The module should receive audio from an analog input and send it automatically to the connected headset.
It is possible to make the module automatically connect to the first (nearest?) discoved device?
Hello Luca,
Unfortunatelly, you need to send a few UART commands for the module to Inquire for close by devices and pair and open a connection.
So you would need a small microcontroller. IOT747 does provide firmware customisation but you need to contact info@iot747.com
