At the end, I have changed some part of my code, reducing delays, and others things and I now, it detects more gpiote interrupts, thank you.

nrf_drv_gpiote_init() will set the priority to GPIOTE_CONFIG_IRQ_PRIORITY, which may be APP_IRQ_PRIORITY_LOW (check this). Try to set the interrupt priority after the init function or change GPIOTE_CONFIG_IRQ_PRIORITY to APP_IRQ_PRIORITY_HIGH.

In main loop, I have a function that uses spi to send / read data and makes calculations, the problem I believe to happen is that i lose all gpiote interrupts when my board is sending or reading by spi.

But I set spi interrupts with low priority:

configuracion_SPI.SPI_PriorityIRQ = NRF_APP_PRIORITY_LOW;	//con softdevice

And gpiote interrupts with high:

NVIC_EnableIRQ(GPIOTE_IRQn);
NVIC_SetPriority(GPIOTE_IRQn, 1);

I need my device detects all gpiote interrupts while it uses spi.

Could you please elaborate a little more, what kind of function do you comment and uncomment? What do you want your device to do?
