gpiote interrupt not taken

/*
 * Setup the gpiote to handle pin events on the MMA8451Q INT1 pin. For the

 */
static nrf_drv_gpiote_in_config_t m_INT1_pin_config =
{
    .is_watcher  = false,
    .hi_accuracy = true,
    .pull        = NRF_GPIO_PIN_NOPULL,
    .sense       = NRF_GPIOTE_POLARITY_HITOLO
};

There seems to be an issue around gpiote interrupts being lost when the pin config is set to low accuracy. This, I note, has been fixed in SDK 11.

We see an issue when the pin config is set to high accuracy.

I need a code sample for the workaround for this issue.

Just so you can mark this as solved:

If you don't have an external pullup, the solution is to set .pull to PULLUP. This way, the GPIOTE IN pin can have a defined state before high to low transition. If the initial value of the pin (which in your case is floating) is lower than a certain threshold (which I couldn't find at the moment), the transition will not be registered.

Setting an internal pullup will result in a high to low transition of VCC->GND and will certainly be registeret as a valid transition.
