adding DFU to Mesh Network

Hi,

Unfortunatetly, we don't have any tutorials that show you how to do this. The documentation I recommend you to read through is:

Proprietary mesh DFU protocol

Configuring and performing DFU over Mesh

DFU example

I think the DFU example will be the most helpful since it illustrates how to create an application that can be updated over Bluetooth mesh using background mode DFU. You will have to try and copy the DFU unctionality available in the DFU example over to your sensor example.

Hi,

We are using

- nrf mesh sdk 5.0.0

- nrf SDK 17.0.2

I had read the infocenter information about the difference between BLE DFU and Mesh DFU. I found out about DFU on lpn being a BLE DFU the same day I posted the question.
We are using a few different boards to test and develop. We have Waveshare dev kit, nRF52840 DK, nRF52840 dongle.
we started the project using sensors example as base, but we will need to find a way to reduce power consumption. I understand why lpn uses BLE DFU, but this won't work for this project.

For now we would like to use mesh DFU running in background. I've seen the DFU example, but I don't know how to merge DFU into another example or project. Do you have a tutorial, or guidance to what should I read / study to learn and figure out how to do it?

Anyway, I was in half way trying to "copy" the idea of DFU from lpn and it is giving me that error.

Thank you

Hi,

Can you provide more details regarding your setup? More info about your use-case would also be useful.

Which mesh SDK version are you using? What device are you using and is it a custom board or DK?

Note that DFU in LPN example is DFU over BLE, so each device will be updated individually and not in the background. You can read more about the difference between DFU over BLE and mesh DFU here.
