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,

The sample you pointed out updates both cores of the nRF5340 simultaneously. Please note that these are the two cores of a single chip, not two separate MCUs.

I am a bit unsure about your use case as well, so I’m not certain how this sample would fit the scenario you described in your original query.

Kind regards,
Abhijith
