+ * @param[in, out] p_len Pointer the length of the buffer, on return it is filled with the event length.
+ *
+ * @details This call allows the application to pull a BLE event from the BLE stack. The application is signaled that
+ * an event is available from the BLE stack by the triggering of the SD_EVT_IRQn interrupt.
+ * The application is free to choose whether to call this function from thread mode (main context) or directly from the
+ * Interrupt Service Routine that maps to SD_EVT_IRQn. In any case however, and because the BLE stack runs at a higher
+ * priority than the application, this function should be called in a loop (until @ref NRF_ERROR_NOT_FOUND is returned)
+ * every time SD_EVT_IRQn is raised to ensure that all available events are pulled from the BLE stack. Failure to do so
+ * could potentially leave events in the internal queue without the application being aware of this fact.
+ *
+ * Sizing the p_dest buffer is equally important, since the application needs to provide all the memory necessary for the event to

+ * format when dealing with both 16-bit and 128-bit UUIDs without having to check for lengths and having split code
+ * paths. This is accomplished by extending the grouping mechanism that the Bluetooth SIG standard base UUID uses
+ * for all other 128-bit UUIDs. The type field in the @ref ble_uuid_t structure is an index (relative to

+
+  @note
+  SVCs, event and option numbers are split into subranges for each API module.
+  Each module receives its entire allocated range of SVC calls, whether implemented or not,
+  but return BLE_ERROR_NOT_SUPPORTED for unimplemented or undefined calls in its range.
+
+  Note that the symbols BLE_<module>_SVC_LAST is the end of the allocated SVC range,
+  rather than the last SVC function call actually defined and implemented.
+
+  Specific SVC, event and option values are defined in each module's ble_<module>.h file,
+  which defines names of each individual SVC code based on the range start value.

+ *      - The notification signal latency depends on the interrupt priority settings of SWI used

+ *        notifications must be configured when there is no protocol stack or other SoftDevice
+ *        activity in progress. It is recommended that the radio notification signal is
+ *        configured directly after the SoftDevice has been enabled.
+ *      - In the period between the ACTIVE signal and the start of the Radio Event, the SoftDevice
+ *        will interrupt the application to do Radio Event preparation.
