Start program when gpio input is set Nrf51-dongle

[aleks]

Hi

We are trying a Nrf51-Dongle in a school prosject here in Norway
We need to use one of the GPIO pins on the Nrf51-dongle as input

When this input is 1 , we want the dongle to run the beacon program for sending notification to cellphone
We having problems finding out of the input/output configuration and syntax for this device

digitalin/digitalout and so from mbed lpc1768 does not work ?

We have the pins P0.15, P0.16,P0.17, P0.18, P0.19 and P0.20 we could use on the Nrf51-dongle



Can anyone please help ?

thanks

Hi,

Are you working on mbed, or using our nRF5 SDK? There are multiple ways to achieve the functionality you want, but the simples might be to use GPIOTE to detect rising or falling edges on the GPIO, and call the softdevice functions for stopping and starting advertising in the interrupt handler. You can find an example of how to detect pin changes in this example.

Best regards,
Jørgen
