MSP432P401R: How to interface UART of MSP423 board with external bluetooth device

Hi,

I am planning to use UART to flash the firmware to the BLE. Here I am using MSP423P401R board. I am using an MSP-FETFlash Emulation tool for debugging. Not the on board debugger. I have connected the SWD pins of Emulator to the SWD pins of MCU MSP432.  Now I connected the RXD and TXD pins of MCU to the BLE. These two pins and supply pins are sufficient to download the flash to the BLE?. 

From the SDK I have taken the UART example code. How can I sedn a .hex file via UART?. Should I include the BLE project in to the MSP432 environment?. Thank you.

    Hello,

        Depending upon if flow control is required, CTS/RTS, will determine if more signals are needed.  If no control is needed, then yes the two pins and the supply pins are sufficient.

    You would need to include the BLE binary in the MSP432 Flash memory.  In this example you will see how another program image (the bootloader) is stored in the MSP.  This is an example of how to include the source in the MSP432 environment.

    Regards,
