BLE Mesh update firmware by NRF SDK

[believer]

Hi,

I am using NRF52832 with NRF SDK 15 and Mesh SDK 4.0.

As my knowledge, I can update firmware for my device using SDK15. I want this cause my network does not have many devices and Mesh DFU takes a very long time.

Can you give me some instructions on how to implement this?

Best Regards,

Hi, 

From our Mesh team's reply about this in this post: 
In theory, this is possible. However, it will require a lot of work, and we haven't tested this so we can't promise anything.
You will most likely run into some problems with the format on BLE-DFU, as it doesn't have the same parameters in the metadata (missing app and company ID). A suggestion from the Mesh team was that it could be better to try and add a GATT service in the Mesh-bootloader with a custom format, even though this will lead to quite some extra work on the phone side. 

I'm afraid I don't have any more specific information about this.

Thank you for your information.

Btw, do you have any plan to implement OTA feature for mesh in both app and devices.

Hi, 

DFU is supported in Mesh, but because the bootloader for BLE DFU and Mesh DFU is quite different you can't have both in the same node. It should be possible to use BLE DFU on Mesh nodes already.

Please beware that the DFU over BLE is not related to the standard Mesh DFU. The reason is that LPN node doesn't support Mesh DFU so we do a normal BLE DFU. 

Please follow the documentation here.
