Methods
  NameDescription
Public methodAddWriteLogStream
Sets the stream to log the write data to.
(Inherited from ConnectionA.)
Public methodBytesAvailable
Returns an estimate of the number of bytes that can be read from this connection without blocking.
(Inherited from BluetoothStatusConnection.)
Public methodClose

Public methodSendAndWaitForValidResponse(BinaryWriter, BinaryReader, Int32, Int32, ResponseValidator)
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.)
Public methodSetReadTimeout
Sets the underlying read timeout value.
(Inherited from ConnectionA.)
Public methodToString
Returns Bluetooth_STATUS:[MAC Address]:[Friendly Name].
(Inherited from BluetoothStatusConnection.)
Public methodWaitForData
Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of maxTimeout milliseconds.
(Inherited from ConnectionA.)
Public methodWrite(Byte)
Writes data.Length bytes from the specified byte array to this output stream.
(Inherited from ConnectionA.)
Public methodWrite(BinaryReader)

Remarks
A BluetoothConnection must be actively open before this connection can be used.
This connection requires Link-OS firmware 2.5 or higher. This channel will not block the printing channel, nor can it print. If you wish to print, see BluetoothConnection. Insecure Bluetooth® connections do not require the device and the printer to be paired.
Examples
using System;
using Zebra.Sdk.Comm;
using Zebra.Sdk.Printer;

        try {
            // The printing channel must be opened before the status channel.
            // Instantiate a printing connection for given Bluetooth® MAC Address.
            printConn = new BluetoothConnectionInsecure(theBtMacAddress);

            // Open the connection - physical connection is established here.
            printConn.Open();

            // Instantiate insecure connection for given Bluetooth® MAC Address.
            statusConn = new BluetoothStatusConnectionInsecure(theBtMacAddress);

            // Open the connection - physical connection is established here.
            statusConn.Open();

            // This sends down JSON to the status channel to retrieve the 'appl.name' setting
            string firmwareVersion = SGD.GET("appl.name", statusConn);

            Console.WriteLine($"The firmware version is: {firmwareVersion}");
        } catch (Exception e) {
            // Handle communications error here.
            Console.WriteLine(e.ToString());
        } finally {
            // Close the insecure connections to release resources.
            if (statusConn != null) {
                statusConn.Close();
            }

            if (printConn != null) {
                printConn.Close();
            }
