long button press / auto reset back to app

[Shay Ohayon]

I need some help with something very basic... I need a way to upgrade my DFU BLE bootloader to either reset back to the app if no update has been sent after some timeout, OR to add a long button press that would reset back to the app. Can someone give me some pointers how I would go about adding such features? Thank you!

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...

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.

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...

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

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