- * This function is called in interrupt context to handle BLE events; i.e. pull
- * system and user events out of the pending events-queue of the BLE stack. The
- * BLE stack signals the availability of events by the triggering the SWI2
- * interrupt, which forwards the handling to this function.
- *
- * The event processing loop is implemented in intern_softdevice_events_execute().
- *
- * In mbed OS, a callback for intern_softdevice_events_execute() is posted
- * to the scheduler, which then executes in thread mode. In mbed-classic,
- * event processing happens right-away in interrupt context (which is more
- * risk-prone). In either case, the logic of event processing is identical.
