NRF52840 buttonless DFU

Hi,

Currently I am adding DFU support to our application, I was able to compile the secure bootloader example and use it.

my next question is, how do I enter DFU mode buttonless? do I need a different version of the bootloader for this, or does it work with the normal secure dfu bootloader?

I read somewhere, that I have to set a register and do a system reset to enter DFU...

what register has to be set to what value, and how can I do this?

note: I am using mbed for my main application, but I think that shouldnt be a problem.

Ps. I can only get the debug version of the bootloader to work, the normal one wont work and also is significantly smaller..?!

thanks,

Jonas
