Thanks, i will try to check that. And try to use the same system with another sensor to see if i have the same issue. I can't do this now so i will try latter and come back here to post some news on my issue.

You should not need the pull down resistor as the sensor should drive the line between 0V and Vdd, but I don't think that is the problem.

I guess you cannot go into debug mode, as the pin reset will not be the same, but you should in some way check if the GPIOTE_IRQHandler is called at all after the reset. Check what the PIN_CNF register of the gpio pin you use is.

It is hard to know what the problem is from the information given.

The gpiote pin config was initialized with GPIOTE_CONFIG_IN_SENSE_TOGGLE(true) and "pull" attribute was set to NRF_GPIO_PIN_PULLDOWN

What is the gpiote pin config (nrf_drv_gpiote_in_config_t)?
