.. _nrf-system-off-sample: nRF5x System Off demo ##################### Overview ******** This sample can be used for basic power measurement and as an example of deep sleep on Nordic platforms. The functional behavior is: * Busy-wait for 2 seconds * Sleep for 2 seconds * Sleep for a duration that would, by policy, cause the system to power off if the deep sleep state was not disabled * Turn the system off after enabling wakeup through a button press A power monitor will be able to distinguish among these states. Requirements ************ This application uses nRF51 DK or nRF52 DK board for the demo. Building, Flashing and Running ****************************** .. zephyr-app-commands:: :zephyr-app: samples/boards/nrf52/system_off :board: nrf52dk_nrf52832 :goals: build flash :compact: Running: 1. Open UART terminal. 2. Power Cycle Device. 3. Device will demonstrate two activity levels which can be measured. 4. Device will demonstrate long sleep at minimal non-off power. 5. Device will turn itself off using deep sleep state 1. Press Button 1 to wake the device and restart the application as if it had been powered back on.
