TBluetoothLE.OnDisconnectDevice

自己作为广播方，连接我的设备断开收到的事件。

TBluetoothLE.OnDisconnectDevice

 TBluetoothLEDevice

BluetoothLE1->DiscoveredDevices->Items[i]->DisposeOf();

 BluetoothLE1.DiscoveredDevices[0].OnConnect;

 BluetoothLE1.DiscoveredDevices[0].OnDisconnect;

procedure TForm7.myDisConnect( Sender : TObject );
begin

end;

procedure TForm7.FormCreate( Sender : TObject );
begin
    BluetoothLE1.DiscoveredDevices[ 0 ].OnDisconnect := myDisConnect;
end;

和下面这个是相反的。

System.Mac.Bluetooth.pas

{ TInternalBluetoothLEManager }

procedure TInternalBluetoothLEManager.centralManagerDidConnectPeripheral(central: CBCentralManager; peripheral: CBPeripheral);
begin
  FLastError := 0;
  FConnected := True;
  if Assigned(FOnDeviceConnect) then
    FOnDeviceConnect(Self, peripheral);
end;

procedure TInternalBluetoothLEManager.centralManagerdidDisconnectPeripheral(central: CBCentralManager; peripheral: CBPeripheral;
  error: NSError);
begin
  FLastError := error.code;
  FConnected := True;
  if Assigned(FOnDeviceDisconnect) then
    FOnDeviceDisconnect(Self, peripheral);
end;

property OnDeviceDisconnect: TDeviceConnectionChangeEvent read FOnDeviceDisconnect write FOnDeviceDisconnect;
property OnDeviceConnect: TDeviceConnectionChangeEvent read FOnDeviceConnect write FOnDeviceConnect;

     FOnConnect: TNotifyEvent;
    FOnDisconnect: TNotifyEvent;

所以可以用TNotifyEvent自定义通知事件来解决。

TNotifyEvent is used for events that do not require parameters.

The TNotifyEvent type is the type for events that have no event-specific parameters. These events simply notify the component that a specific event occurred. For example, OnClick, which is of type TNotifyEvent, notifies the control that a click event occurred on the control.

The Sender parameter is the object whose event handler is called. For example, with the OnClick event of a button, the Sender parameter is the button component that is clicked.

property OnDisconnect: TNotifyEvent read FOnDisconnect write FOnDisconnect;

// will be invoked once disconnected

-(void)centralManager:(CBCentralManager *)central
  didDisconnectPeripheral:(CBPeripheral *)peripheral 
                         error:(NSError *)error;
