Updating one nRF52 DK board with another, automatic OTA

Hey, just stumbled across this thread. I am looking at a similar problem and was wondering if you were able to complete this task. If so, do you by chance have a copy of the project? If not, do you have any additional resources for someone that is looking to replicate this process?

Any help would be greatly appreciated.

Hmm this is similar to what I was thinking, thank you for this reply, it gives me an idea of how to approach this. I was looking at the python code and the port seems pretty doable.

Hi.

Here is a proposal for what you could do:

You first must find out if the nRF52 DK you wish to update requires an update.
Second, you must store the DFU image you wish to use on the DK you wish to update from.
Last, you must port the part of nrfutil which is responsible for the DFU transfer, from Python to C. There source file for the Python implementation can be found here, and you can find more in-depth information about how the packets are sent over BLE here.
