Hello,
I have trouble with interrupt.
I use pin 16 to trigger interrupt signals from a sx1261 module.
It has worked well on example code with SDK 14, but for my projet I have to migrate to SDK 15.2. Since migration I am not able to detect interrupts.
I have changed nrf_drv_spi and nrd_drv_gpiote drivers to nrfx drivers.
I think I missed a step while migrating project.
Do you have any idea of something wrong ?
Thank you
this is part of my project related with gpio interrupt:
GpioInit(&SX126x.DIO1, PIN_LORA_DIO_1, PIN_INPUT, PIN_PUSH_PULL, PIN_NO_PULL, 0);
GpioSetInterrupt(&SX126x.DIO1, IRQ_RISING_EDGE, IRQ_HIGH_PRIORITY, dioIrq);

{

}
}

{
nrf_gpio_pin_pull_t pull_config;

return;
obj->pin = pin;
