Radio Notification Context

Question

Hello, 
 I have a problem using the radio notifications. I use the softdevice V. 15.3.0. 
 I would like to have an interrupt every time I send an advertisement, which I can achieve using: 
 ble_radio_notification_init( 2, NRF_RADIO_NOTIFICATION_DISTANCE_800US, interrupt_func) 
 While this is working fine on its own, the interrupt is not only triggered by advertisements, but also from radio activities coming from a scanner which is running simultaneously. Is there a way to find out if the interrupt was triggered by advertisement or the scanner? Also if I could just get an interrupt when advertising this would be fine. 
 Best Regards, 
 Lukas 
 Edit: Wrong naming, mistaken advertisement and notification.

Hi, 
 Oh well, I see.. The thing with using radio notifications is that it's totally agnostic over what happens on the higher layer, it only cares if the radio is Active or not. There isn't a specific event that is generated when the nRF are advertising. You can always do this indirectly by setting a flag once you've started advertising in the application, but it won't necessarily be precise as the Softdevice has to schedule the task i.e put in the queue and execute it. But it will in most cases work fine

Hi. 
 The function that you're referring to is apart of the radio notifications API, which will notify the application every time the radio is in use. The S112 softdevice will produce a BLE_GATTS_EVT_HVN_TX_COMPLETE event every time a BLE notification is sent. You can implement the event in the switch case in the gatt handler in your project.
