Hello,

I want to apply the long press(3 sec) button functionality to turn off the BLE and communications(in my case SPI)

I went through nRF9160 Feather blog its different

I am facing difficulty to apply the long press button

Now I am trying to implement press the same button for 3 sec to turn/off the led.

press the same button and change the state of led

Please suggest some inputs

Thank you in advance.

Hello,

There is a blog (+) How to use the nRF9160 Feather - Blogs - Nordic Blog - Nordic DevZone (nordicsemi.com) you can look at how to use GPIO pin as switch.

You can also look at this sample nPM1300: One button (nordicsemi.com) to know button can control the device state. This sample controls LED, load switch and power mode of nPM1300 based on button press.

One GPIO pin is configured here as an interrupt output which is used to signal the button.
