How to configure to wake up from SYSTEM_ON and SYSTEM_OFF using RTC2 (periodically) and from GPIO pin change

[V.Lorz]

Hi,

I need to configure an nRF52832 to wake up periodically from SYSTEM_ON and SYSTEM_OFF and, also, when a GPIO pin changes.

Where can I find sample code and docs for this?

I'm using nRF Connect SDK version 1.9.1 and Visual Studio Code.

Hi

This looks much better. The spikes look like the auto-controlled refresh mode being active, where the frequency depends on the current being drawn on the regulator output. In system OFF mode the refresh interval is at 100-150ms.

The current consumed during refresh modes are documented here. Note that the numbers in the PS are typical numbers only, and there will be device to device variations.

Best regards,

Simon
