Hi Nordic team,
I have a 52832_xxaa processor with SDK 14.2 and Softdevice 5.1.0. My App run without problems if I only add SD. No problems as well if I add my bootloader (incl. App Settings).
A DFU from my mobile (Sony with andriod, last version) doesn't work.
To prove my bootloader is ok, I tried the buttonless example from the SDK first. Setup was: SD + my bootloader + settings flashed via nRFConnect J-Link Programmer.
With this setup, I can see DFUTarg on my mobile, start DFU, transfer the example and successfully start the example app after reset.
If I do the same with my app, the DFU transfer works well and also after reset I can see my app runing correctly. If I try to DFU my app again know using my app as buttonless DFU service, the DFUTarg (bootloader) is starting, but no transfer of data happens.
Here is my log file, I hope you can help my finding the source of the problem.
