mesh models dfu metadata encode

[Sergnrf]

Hi Team,
NCS v2.4.0

I do everything according to the instructions developer.nordicsemi.com/.../dfu_over_bt_mesh.html

mesh models dfu metadata encode 2 0 0 0 241236 1 0x71f3267c 1


23:23:51.845 -> For a detailed description of the commands and arguments in this shell module,
23:23:51.845 -> please refer to the Zephyr Project documentation online.
23:23:51.878 -> 
23:23:51.878 -> [1;31mmetadata unknown command: encode 

How to fix?

In the old SDK it was easier, 
when  it will be user  friendly?

Thank you.

Hi Serhii, 

The mesh DFU in nRF Connect SDK is relatively new and it follows the new DFU protocol in the new Mesh specification. So it's quite different from the mesh DFU we had in the nRF5 SDK. 

Could you send the whole log when you compose the firmware data ?

Hi Serhii, 
Could you try: 

mesh models dfu metadata-encode <Major> <Minor> <Rev> <BuildNum> <Size> <CoreType> <Hash> <Elems> [<UserData>]

I think it's mistake in the documentation. 

[Sergnrf]

Please add a broader description of all parameters.

[Sergnrf]

What is wrong with this command?

Hi Serhii

A dash is needed between metadata  and encode, so it should be 

mesh models dfu metadata-encode 2 0 0 0 241236 1 0x71f3267c 1
