Reset nrf52832 on Short press and factory set on the Long press

[AimHigh]

Hello,

Good Day!!

My question regarding the reset functionality of the device.

Reset the device on the short press of the reset button and on Long press (for example 8 seconds) device must erase the user data and set back to factory settings on nrF52832. I would love to hear ideas on the implementation part to this problem.

Thank you

Hi,

I would simply do a nvic_systremreset() on short button press.

In the beginning of main() have a check if button is pressed, and a for-loop of 8000 using nrf_delay_ms(1) while button is pressed. 

If button is pressed 8000ms, then erase flash pages and continue to run in main().
