Hi Shay,

I suggest that you use the Watchdog Timer to implement a timeout if there is no DFU activity as explained in this answer.

Best regards

I'm afraid this is too simple code. For long press you should probably listen for any GPIOTE change on the PIN, start timer when it gets pressed (= check GPIO state and start timer could be done in interrupt handler) and then check its counter when another interrupt happens and the GPIO state is the opposite. Look to these two SDK libraries and combine them.

i'm looking at this example: github.com/.../main.c How would you detect a button de-press with this library?

This is why I posted the question here. I can't implement bootloader with mbed. it must be low level....

Most of people here use nRF5 SDK directly. If you want to keep using mbed then I believe their SDK have similar basic modules, their forum seems to be active as well...

I'll look into those. Thanks. I haven't had a chance to read the full SDK documentation. I'm mostly using mbed for high level stuff.

What do you mean by pointers? You need to write the code yourself. Do you need to help "app_button" and "app_timer" libraries from nRF5 SDK (\components\libraries)? These are pretty easy to use...
