nRF5340 BLE DFU from NET core

[valeriy_simakov]

Hello! 
Introduction. Responsibilities of the cores in my device:
1. app core. 
1.1. data processing from a stereo microphone
1.2. data sending to net core.
2. net core. 
2.1. ble communication, services supporting. 
2.2. data receiving from app core.

Everything works fine :)
But now I want to add BLE DFU )

As I understood from examples, I should use app core for smp server, so I should use ble communication support on app core, which changes my whole architecture.

Could please anyone help me with that situation? :)

Hi,

What you want to do is not the standard way to do stuff, so it is not supported or tested.

However, it can be done.

First, tell me: Do you want to update both cores?

How large is your network core application?

Regards,
Sigurd Hellesvik

1. Connect to it with the Android app nRF Connect and enable notifications.

2. Press button 1

3. Watch logs

Sigurd Hellesvik  could you please specify which version of sdk should I use to build your project?  

[Sigurd Hellesvik]

I tested with v3.0.0 yesterday, if I remember correctly

[valeriy_simakov]

I tested with my phone (nrf Connect).
I got about 300kbps.

I forgot to say thank you for your example)
I got more faster speed for 6400KB !

I've modified your example to fit my task. And I made two options, with waiting for sending and without, like yours. The waiting for sending option turned out to be slower.
