RAK811 update firmware
Hi RAK team,
i need to add the possibility to update the RAK811 in our product.
Please, i would like to know what is the protocol to do it ?
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 !
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).
@eiten Thank you for sharing.
my RAK811 module are now on my application board.
i can't remove it ! so i need to allow flash firmware update from my application.
Edi propose a solution, but it's surely not the simplest.
Please can you provide a more friendly solution with some news AT commands ?
@phil31 Because the way we upgrade firmware is also the official way to upgrade, so at present only one of the possible solutions mentioned above.
