NUS shut down & restart

[John Galvin]

I've built a project based on the peripheral_uart appliction. This is working well, but I need to now sort out the lowpower mode. My product is battery powere & I need to turn everything off when the power button is pressed.

Is there a deffined way to do this?

I will also need to restart it when the power button is pressed again.

Hi John,

You could use the sys_poweroff() API for the same.

First configure the button GPIO as input and set the sense mechanism (so it can wake the device from System OFF). Then call sys_poweroff() to enter System OFF mode. 

This ticket could help you get a idea.
