How to use Interrupt in BLE Central

[June1993]

Hi all Nordic Developer,

Currently I am working on nrf51-dk(as a BLE central) and I wish to connect one of its pin to a power supply(as a input). If the power breakdown, it should send out a warning message. I guess using an interrupt might be a good idea to handle it. How can I do this??

Thanks

Please have a look at the documentation of the GPIOTE driver and the APIs for GPIO and GPIOTE abstraction. You can find an example in the pin_change_int example found in SDK12.
