DETECT Signal Is Not Bringing System Out Of Systemoff State

I tested this code in an application, and I'm not having any issues with waking the chip from System OFF using this APIs.

Can you please post your full project for us to reproduce and debug it?

My code snip above shows I use NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);

I also added nrf_gpio_cf_sense_set(NRF_GPIO_PIN_MAP(1, 5), NRF_GPIO_PIN_SENSE_HIGH);

That did not help though.

Hi,

You have configured the pin with hi_accuracy (GPIOTE IN event) through the GPIOTE driver by setting NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(true). The driver will only enable sense for the GPIO if it is configured using hi_accuracy=false, or PORT event.

You can enable sense on the GPIO by calling nrf_gpio_cfg_sense_set() before entering System OFF.

Best regards,
Jørgen
