Many thx. That was the issue. I had too much faith that ble_radio_notification.c was correct. All compiles fine now without moving up to a later SDK :-)

Also, I notice in ble_radio_notification.c they failed to put the #include for the nvic. You need to put this there it won't follow it if you just put it in main.c So add to it:

#include "nrf_nvic.h"

I use Keil uVision but the same is true for all compilers. The only thing that you likely did wrong was to not include the path for nvic in the C paths in the compiler settings. \components\softdevice\s132\headers
Double check that and also that you included the radio notification path. Even then sometimes Keil complains about missing pieces and then I also will include the actual files in the project. Then do a rebuild all target files and you should be good to go.

Oh, I think I get what you are saying. You haven't included those API's it's just giving an error on compile. Sorry for the misunderstanding. Looking into it now.

There is no need to call any of those API's for radio notfication. It is literally what I put in the answer.

The (ble_radio_notification_init) api call sets the priority, and the SD enables any irq functionality in the nvic and points the vector to your handler. Also I see no mention of the radio notification IRQ number in the SoC library. So, I think that is private and not public. So there would be no way to use those API's anyway.

Thx ambystomalabs. That is the code I have but I am still getting sd_nvic_ClearPendingIRQ, sd_nvic_SetPriority and sd_nvic_EnableIRQ undefined when I compile it.

I did try #include "nrf_nvic.h" but this does not fix it.

I just checked the 12.3 API reference and everything is the same in 12.3. So, just use what I put in the answer below. There is no need to clear pending, or assign the IRQ level as you noted above. That stuff is all part of the API.

I should point out that was done in SDK11, but the API for radio notification hasn't changed in a while. So should be the same.

Not sure about which aspect of radio notification you are having trouble with, but here is everything you need.

       #include "ble_radio_notification.h"

       #define RADIO_NOTIFICATION_IRQ_PRIORITY 2
       #define RADIO_NOTIFICATION_DISTANCE NRF_RADIO_NOTIFICATION_DISTANCE_5500US //There are many options on distance.  Just look in spec
//This is the interrupt handler
    void radio_notification_evt_handler(bool radio_evt)
{

    if (radio_evt)
    {
//This is where radio is about to start. ie, notification distance before
			
} else
{
//This indicates radio has just finished.  No delay here occurs right after radio stops.
}		
}

//This bit goes in main AFTER you have started the SD.
		err_code=ble_radio_notification_init(RADIO_NOTIFICATION_IRQ_PRIORITY,RADIO_NOTIFICATION_DISTANCE,radio_notification_evt_handler);
    APP_ERROR_CHECK(err_code);
