Hello
I'm exploring the mesh dfu transfer, get some strange results
Here is the setup
1 distributor, 1 target
On the distributor I start the transfer with mesh models dfd start 0 0 command
In about 40 minutes it completes, and the image is applied but I get a timeout message on the distributor side
However on the target I see a message from the mcuboot that the new message was applied successfully - and actually it is working just fine
Log from the distributor and the target below
Another question
The progress in the JSON below is "50" which I think is because the function that calculates progress divides by 2:
DFU progress: 100 %
