    Hi, phil31
    Do you want us to provide you with some firmware information?If so, please leave your email and we will contact you as soon as possible.


  • i just would add the update firmware feature from my main CPU.
    my main CPU will receive the .BIN firmware by a USB link and our application, then the CPU need to program the module.

    what is the used protocol to update the module please ?
    you can join me on my email too !


  • Hello phil,

    you can find the details here. It's not RAK-Specific, you can programm the stm32l151cb-a via the bootloader (set BOOT0 high, flash RST, programm, set BOOT0 low, flash RST).

    Regards, Edi
