gpiote interrupt never gets hit

[the_purple_pig]

Hi, I set up a 2 GPIOTE interupts like this:

in main.c:

APP_GPIOTE_INIT(3);
err_code = app_gpiote_user_register(&mainUser, 0x00000000, (1 << RF_GPIO2), powerButtonInt); APP_ERROR_CHECK(err_code);
err_code = app_gpiote_user_enable(mainUser);
APP_ERROR_CHECK(err_code);

and then later in another file:

uint32_t err_code;
err_code = app_gpiote_user_register(&radioUser, 0x00000000, (1 << RF_GPIO0), radioInt);
APP_ERROR_CHECK(err_code);
err_code = app_gpiote_user_enable(radioUser);	//leave it disabled for now
APP_ERROR_CHECK(err_code);

But my interrupt functions never get hit. I cannot understand why. Any idea where I can start to look?

Ok, so I see that if I do get GPIOTE interrupts working just fine, if I comment out some (necessary) serial comms code in between initialising the SoftDevice and proceeding with my app. If I uncomment what is commented out below, I never get the GPIOTE interrupt. How can that be?

APPL_LOG("init SD\n\r");
InitSoftDevice();
InitHardware();     //this is where GPIOTE interrupts get set up

//while(SendData == 0)
//{
//  if(HostDetected == 0)               //HostDetected is set to 1 when the host replies to below
//  {
//    app_uart_put(0xAA);		//lets the host know this MCU is ready for comms
//    app_uart_put(VERSION);
//    nrf_delay_ms(50);
//  }
//}

nrf_delay_ms(10);		//allow the ACK to be sent via serial port

--proceed with application
