Hi,

I am sorry for my too late reply. I have worked on the other parts of the project.

I am now working on this part. I founded out my problem was the start address of the application in the flash. I managed to solve this by changing that.

Hi again.

Do you have any logs for the attemted DFU? Anything that could give a pointer to what the problem might be?

Thanks for confirming.

I'll talk to one of my colleagues with more experience with DFU about this and get back to you.

Hi,

Yes, I installed the customised nRF util.

I think the problem is with the address the application should be placed in, after receiving. I do not know how I can change that and what it must be, to work correctly.

I look forward to hearing from you.

Regards,

Sama

Hi.

You should be able to perform a DFU on the dongles with your described setup.

First of all:

To perform DFU transfers over Bluetooth mesh you need to use a customized version of the nRF Util tool.
This tool sends the DFU packets to one device over serial interface. This device then stores these packets, and also forwards them to the other devices withing the radio range.

The nRF Util is available at https://github.com/NordicSemiconductor/pc-nrfutil/tree/mesh_dfu. The tool is open source.

Are you using the custom version of nRF Util designed for Mesh?
