GPIO Input Current Consumption very high when pressed

Hi there! I'm sorry to add on 3 months later but I'm curious of something. This same exact thing happens when using the BSP button short/long press. Is there an equivalent to this default config for bsp short/long press?

Thank you!

Hi,

You set the pin with an internal pull-up resistance of 13kOhms and 3.3V it will give a current of ~250uA if the pin is hold pressed down.

If you want to keep the button pressed down for long period of time I recommend you clear the pin after it's the pressed in the interrupt handler with nrf_gpio_cfg_default().

Best regards,

Marjeris

I don't believe that can be the issue, as the soft device uses a timer also.. and when ble is avertising without button being pressed the current consumption is very. As predicted.. only when button is pressed the consumption increases...

I guess the 250 uA from your timer, how much about your timer?
try to stop your timer before into deep sleep
