  1. Overview


    The BM90 is a fully-certified Bluetooth specification version 4.2 bluetooth low energy module. It integrates ST Microelectronics BLUENRG-132 soc chip with bluetooth 4.2 stack, 2.4GHz transceiver and RF power amplifier. With the BM90 module, designers can easily and rapidly embed bluetooth functionality into any devices and provides cost and time-to-market savings as a self-contained module solution.

    It supports GAP、GATT Profiles and Data is transparent transferred over UART interface.Configuration is made easy using AT commands.

    In addition, BM90 also supports master or slave role, one to more connection or ble mesh application.

5. Bluetooth Software


 

 

 

6 Reference Design

Reference schematic for UART Transparent Application:

 

Note:

  1. pull up exists in module Reset pin
  1. Bootloader is activated by hardware by forcing DIO7 high during power-up or hardware Reset,
    The customer application must ensure that DIO7 is forced low during power up.
