Yes

You can use this menu to check which versions it is supported for:

Is this supported in v2.3.0? or v2.4.0?

Hi,

Yes, it looks like MCUmgr callbacks are not yet supported in 2.2.0.

Thanks, Sigurd,

I think that CONFIG_MCUMGR_MGMT_NOTIFICATION_HOOKS is not supported in ncs2.2.0 right?

best regards!

[quote user="Mustafaq"]* downloading image using BLE ( DFU callback) [/quote]

See MCUmgr Callbacks.
You can see an example of this in our matter samples.

[quote user="Mustafaq"]prepare an application for a reboot [/quote]

If you are using the "os_mgmt" for reset, it should be similar to the above solution.

[quote user="Mustafaq"]and after that Callback in the bootloader level for swapping the image and upgrading the fw. [/quote]

In this case, CONFIG_MCUBOOT_ACTION_HOOKS is the way to go.

However, as far as I can find, you can not add these hooks from your project.
I think that the easiest way to do this would be to add a ".c" file with your hooks to the bootloaders/mcuboot/boot/zephyr/

Here is a sample showing one possible solution.
It may not be the best solution, as the MCUboot project is not built for our multi-image build concept, but it seems to work as expected on my end.

This code/configuration is not thoroughly tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.

Hi Sigurd,

Actually what I meant is that I would like to have a callback on the application level for the following events:

* downloading image using BLE ( DFU callback)

* prepare an application for a reboot

and after that Callback in the bootloader level for swapping the image and upgrading the fw.

I aim to attach a led indication by every step to inform the user about the progress steps.

for MCU bootloader I'm using the zephyr device management

Best regards,

Mustafa

Hi,

There is a difference between a Bootloader and Device Firmware Update (DFU).

The Bootloader boots and swaps images.
DFU transfers images to the device.

When you are downloading a new image over Bluetooth Low Energy, this is DFU and is handled in the application. The Bootloader is not active during this.

Are you using Zephyr Device Management to perform DFU?
