Setup:

Software: We are using DA14583 IoT Sensor for the reference design and run the RAW Project.
Hardware: The original design to control the power is based on a switcher, which means that when the switcher is off, the MCU will stop to work.
However, for real application, we would like to change the original switcher design to "softly" control, by entering the extended sleep mode and disable advertising if the button is not pressed.

As a result, we would like to revise the original firmware to realize the “wake-up“” function.

Questions:

Now we would like to wake up the DA14583 and start advertising with the press of a button (Input P2_1). How can I do that in RAW Project?
Could you please some hints to me. Thank you very much!
