The latest SDK can be downloaded from this page. If you are using nRF51822, the latest supported release is SDK v12.3.0. Most examples in the SDK use system ON idle mode when there is no work to be done by the CPU. You can also use GPIO for wakeup from system OFF sleep mode, but this is not implemented in the Pin Change Interrupt example.

Hi,

I am working on the same and I need to developing code using "pin_change_int" as reference to develop the interrupt based event and calling the function assign to it.

Can please me sample code to get the better clarification.

And one more thing that I am concern about that does it support sleep mode or not, because I am looking for the sleep after works get completed.

Looking for the kind support and help ...

Thanks

Yes, unless you configure the pin in a way that it will constantly generate interrupts, the chip can enter sleep mode.

Hi,

If I use this Pin Change Interrupt Example with "ble_app_uart" example, then code will be able to enter into the "SLEEP MODE" or not ....??

Hi Andreas,

There is a Pin Change Interrupt example in the SDK. This use the GPIOTE driver, but it is also possible to GPIO sensing to wake up from sleep. It should not be too hard to change this example to start a timer on the toggle of the input and increment your variable in the timer callback handler.

Best regards,

Jørgen
