Entering ON/low power mode

[Florence]

I am trying to make the nrf52832 enter in ON/low power mode for inactivity periode.

I must have the "System ON, No RAM retention, Wake on RTC" as indicated in nrf52832 datasheet, table " Current consumption: Ultra-low power ". Then the system must wake on RTC timeout. Is there simple code to do that?

I tried the  "sd_power_mode_set(NRF_POWER_MODE_LOWPWR)" without any success. I can't find a clear explaination in the API.

Best Regards

I believe all \ble_peripheral examples do what you describe:

The app_timer (using RTC) is used to periodically wakeup the chip at given intervals and write data to softdevice (for instance battery level) to be notified to the peer device. The idle current is only a very few uA. If you are planning to create a BLE application I suggest you start with this.
