Beaconing application - begin code with system off, press button to wake up

[AQS]

Hello,

I am working on a beaconing application and I was wondering if it is possible to run the code beginning with system off mode and wake up the board with a button press? Once I wake up the board, I would like it to immediately begin advertising. Am I able to initialize all my functions before entering system off mode?

Thanks for the help

Waking up from System off will reset the system, so you will have to re-initialize everything. 

Your use-case is demonstrated in the ble_app_uart example with the help of the Board Support Package (BSP), I suggest you read BSP BLE Button Assignments.
