Zephyr MCUmgr client

[QuentinD]

Hello,

In my device I have a nrf52840 which communicates with a STM32 via uart.

In my nrf52840 I use the MCUboot.

Is there any documentation or source code that would allow me to implement what mcumgr does to send an update to the uart (to implement in my STM32) ?

THANKS

Hi, 

Unfortunately, there is no sample as your requirement, but you could check out https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/central_smp_client/README.html 

The DFU is done using the SMP Protocol, which you can find explained under Device Management docs.
