BLE DFU update for multiple mcu architecture

[Beldramma]

Hi,

I am on NCS 2.9.0, I have tested lesson 5 exercice from NRF Intermediate course about BLE DFU, I have some questions about it:

- with mcumger, is there a way to update different mcu ? Like I receive firmware from mcu A through BLE, to update mcu B ? Maybe put information about which chip to update in firmware file.

- I have seen that this example uses a fixed service/characteristic, is it possible to use this service in our products legally, when they will be sold ?

- Is there a way to modify this service, or a way to use another custom service ?

Thanks !

Hello and happy new year !

Sorry for the delay, I was on others topics. 

Menon Hieu , I have read again MCUmgr documentation, and it seems that in order to do what I want to do, ( have possibility to update local Nordic firmware on micro A, but also external micro), if i want to continue to use img management ID and make it transparent on BLE initator side, I have to use a custom img_mgmt handler, and not use the one in NCS, do you confirm ? Do you see others ways to do that ?

Hi Beldramma,

Happy new year to you too.

I am afraid I don't fully understand the question. Could you elaborate in detail and give some links to what you are referencing?
