Implementation

    switch (event) {
      case 0:
        return L2CapConnectionState.disconnected;
      case 1:
        return L2CapConnectionState.connecting;
      case 2:
        return L2CapConnectionState.connected;
      case 3:
        return L2CapConnectionState.disconnecting;
      case 4:
        return L2CapConnectionState.error;
      default:
