Thank for answer,

I saw your link. And I understand like this. I will flash Bootloader + Bootloader setting + SD + Mesh Application. After I can go to Boot via button from Mesh App and update normal. I can think of a mesh app like a normal app in the BLE SDK and run DFU. Right ?

Thank you !!!

Glad to hear you say,

So I don't know How Bluetooth mesh examples organizes memory map and whether it is the same as the SDK BLE example.

Can you send me the memory map organization that mesh sdk uses ?

If it same SDK BLE, I can flash bootloader DFU and update it normal.

Thank you !!!

If you still have problems, I suggest that you create a new support ticket.

Hi.

[quote user=""]Can I add DFU buttonless for other mesh example similar to with Low Power Node. Such as Light switch client,server examles.[/quote]

Yes, that should be possible.

Note that currently we don't have an integrated option to have both Mesh DFU and BLE DFU. You would need to choose one. So in your case if you only need to update the node via BLE, you can just flash the normal BLE DFU bootloader, and find a way to send the device to switch to DFU mode (either by a physical button , or buttonless via a Mesh command)

There are also several threads on devzone discussing how to add Buttonless DFU to a Mesh example.

I just tried to install the example following the the mesh dfu quick start guide.

I had many errors on the pip install requirements.txt operation.

how did you get around this.

Also for Nordic is the a version for python 3.
