Bump.

Did you try my suggestion? Do note that the example is setup to toggle the output on pin change, so this means that the LED is turned ON once when button is pressed.

Kenneth, can you confirm with the development team that is there is a difference in how GPIOTE_CONFIG_IN_SENSE_HITOLO(false); works and how GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);

As I believe on using GPIOTE_CONFIG_IN_SENSE_HITOLO(false); it is working fine on low accuracy.

Also can you try these on your end performing HITOLO and LOTOHI.

When I use:

GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);

It keeps on giving interrupts even though there is no low to high pulse. But when I set the condition to true it works just fine.

Are you using "\nRF5_SDK\examples\peripheral\pin_change_int" as-is here? It seems to work on an nRF52-DK I have here when I change to nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(false);
