Device not found due to failure during DFU

[kdoteu]

Hi there,

for a small project we wanted to use the 52840 Dongle as advertisement scanner as you did.

But if we use your precompiled hex-files the programmer fails with
"Device not found due to failure during DFU"
because the stick seems to not booting anymore.

Eventually you can help us ? As you mentioned we used both hex files softdevice and motam scanner.

I also tried to use softdevice from nordic direct and so on.
