Stereo module support UART command set to make an external MCU to control module.

Here is the connection interface between BMXX and MCU.

FIGURE 2-1: INTERFACE BETWEEN MCU AND BMXX MODULE

MCU can control module by UART interface and wakeup module by PWR pin. Stereo module

provide wakeup MCU function by connect to P0_0 pin of module.

“UART Command Set” document provide all function which module support and UI tool will help

you to set up your system support UART command.
