Found the error. It looks like this function:

nrf_drv_gpiote_in_config_t config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);

should be

nrf_drv_gpiote_in_config_t config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);

Thank you Hung

Hi Pablo, If you read the PAN again: "1V2 + HFCLKarerequested always when the GPIOTE task is configured."

You can find that it's GPIOTE task is what described in the PAN, not GPIOTE event.

The GPIOTE event would always requires 1V2 and HFCLK to detect the pin level changes.

If you want detect a button press with low power consumption, please use GPIO PORT event instead.
