Radio notification only after BLE radio

[Geir Strand]

I'd like to get a notification every time after the radio has been active (as shown as NACTIVE in the S110 rev 1.3 spec). How can I make this mappen?

I see two functions available: sd_radio_notification_cfg_set and ble_radio_notification_init. Are these two functions supposed to work together or should we only use the ble_radio_notification_init? This does not have configuration of the notification events, only the distance to next active radio period...

Like this:

bool current_radio_active_state = false;

void ble_on_radio_active_evt(bool radio_active)
{
    current_radio_active_state = radio_active;
}

static void radio_notification_init(void)
{
    uint32_t err_code;

    err_code = ble_radio_notification_init(NRF_APP_PRIORITY_LOW,
                                           NRF_RADIO_NOTIFICATION_DISTANCE_800US,
                                           ble_on_radio_active_evt);
    APP_ERROR_CHECK(err_code);
}


int main(void)
{
...
    radio_notification_init();
...
}

So, just asking for clarification. If I use this example to set ble_radio_notification_init in conjunction with sd_radio_notification_cfg and set the TYPE to NRF_RADIO_NOTIFICATION_TYPE_INT_ON_INACTIVE, it will ignore the distance setting and provide a radio notification on inactive?

When I use this code with SDK 7.1, I get this warning:" warning: implicit declaration of function 'ble_radio_notification_init' 'is invalid in C99". I don't get compilation errors, but I cannot build the project. Why could this be?
