Bluetooth Data Access

A task processor with payload handling is needed to access data over a native serial connection (COM) over bluetooth.

Task Processor

The payload processing must be declared in a processor information within the device info file.

The payload script is typically placed in the folder:

$(ConfigPath)\HumanOS.UHAL.BluetoothDeviceDriver

Example

  "TaskProcessors": [
    {
      "Id": "9bd3ec86-f5fe-4679-8621-751540d602a2",
      "Name": "MainTaskProcessor",
      "ScriptFile": "TTestPayload.cs",
      "Properties": []
    }
  ]

Builtin Addresses

Following data node addresses are provided by the plugin. The Stream namespace is used:

Address	Description	Data Type
Stream::Available	Returns the available flag. true if the data stream is open.	System.Boolean
Stream::SignOfLife	Sign of life. Toggles in 1Hz if the data stream is open.	System.Boolean

Example

/// <summary>
/// Test payload for script
/// </summary>
public class TTestPayload : TAbstractStreamScriptObject
{
  ///<see cref="TAbstractStreamScriptObject"/>
  public override void handleStream(IKernelAccess Kernel, 
                                    ILogger Logger, 
                                    TDeviceInfo DeviceInfo, 
                                    IDataStream DataStream)
  {
    byte[] aui8Buffer = new byte[4];
    DataStream.read(aui8Buffer, 0, 4);

    aui8Buffer[0] = 0x11;
    aui8Buffer[1] = 0x21;
    aui8Buffer[2] = 0x31;
    aui8Buffer[3] = 0x41;

    DataStream.write(aui8Buffer, 0, 4);
  }
}
