Overview

This section defines the event, structure and types for Bluetooth panic feature.

How to use this module

The panic event is triggered when Bluetooth host or controller has asserted or crashed. Once the panic event is received, the Bluetooth has to reboot.

• Sample code:

  // The application reboots the Bluetooth, once Bluetooth panic event is received.
  bool is_panic = false;
  bt_status_t bt_app_event_callback(bt_msg_type_t msg, bt_status_t status, void *buf)
  {
      switch (msg)
      {
          case BT_PANIC:
              is_panic = true;
              if (((bt_panic_t *)buff)->source == BT_PANIC_SOURCE_HOST) {
                  // Host is the source of panic event.
              } else {
                  // Controller is the source of panic event.
              }
  
              if (bt_power_off()) {
                  // The Bluetooth powered off successfully.
              } else {
                  // The Bluetooth power off has failed.
              }
              break;
          case BT_POWER_OFF_CNF:
              {
                  if (is_panic == true) {
                      if(bt_power_on(NULL,NULL)) {
                          // The Bluetooth powered off successfully.
                      } else {
                          // The Bluetooth power off has failed.
                      }
                  }
              }
              break;
          case BT_POWER_ON_CNF:
              {
                  if (is_panic == true) {
                      is_panic = false;
                  }
              }
              break;
          default:
              break;
      }
      return status;
  }
