Thanks for the documentations. The softdevice_handler.c is used in the advertising part of my program, which is essentially based on one of the SDK examples, so that file has to be included. Also, I need to have the Observer example added to the program, which is using SWI2_IRQHandler. So, these two handlers have to be merged. As I'm doing scanning and advertising sequentially and not at the same time, does it make sense to add a switch case in the SWI2_IRQHandler and do whatever the examples are doing based on whether the timeslot scanning or normal advertising is being used (just as a very quick setup to get rid of the error)?

Hi FA,

They all come from the same source, the softdevice event notification that use the SWI2 to notify the application. Please have a look in the Softdevice product specification, look for "Application signals - software interrupts"
I don't think normal advertising have anything to do with softdevice event, except for the advertising timeout event.

My suggestion for you is to do some more study on a normal example to understand how the softdevice event handle works. Then you can have a look at the timeslot documentation in the softdevice specification (download from our website). A tutorial on how the timeslot works can be found in the tutorial section here.
