Open Source GXBluetooth media component, made by Gurux Ltd, is a part of GXMedias set of media components, which programming interfaces help you implement communication by chosen connection type. Our media components also support the following connection types: serial.

Build

If you want to build example you need Nuget package manager for Visual Studio. You can get it here: https://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c

Simple example

Gurux Bluetooth component doesn't search available bluetooth devices. It will only use bonded devices. You can bond the Bluetooth device from the Android Bluetooth settings.

Before use you must set following settings:

• Device

It is also good to listen following events:

• OnError
• OnReceived
• OnMediaStateChange

GXBluetooth bluetooth = new GXBluetooth(this);
bluetooth.Device = bluetooth .GetDevices()[0].Name;
bluetooth.Open();

Data is send with send command:

bluetooth.Send("Hello World!");

It's good to listen possible errors and show them.

bluetooth.OnError += (sender, ex) =>
{
   // Show error.
};

In default mode received data is coming as asynchronously from OnReceived event.

bluetooth.OnReceived += (sender, e) =>
{
    try
    {
        MainThread.BeginInvokeOnMainThread(() =>
        {
            if (hex.Checked)
            {
                receivedData.Append(GXCommon.ToHex((byte[])e.Data));
            }
            else
            {
                receivedData.Append(ASCIIEncoding.ASCII.GetString((byte[])e.Data));
            }
        });
    }
    catch (System.Exception ex)
    {
        ShowError(ex);
    }
};

Data can be send as syncronous if needed:

lock (bluetooth.Synchronous)
{
    string reply = "";
    ReceiveParameters<string> p = new ReceiveParameters<string>()
    //ReceiveParameters<byte[]> p = new ReceiveParameters<byte[]>()
    {
       //Wait time tells how long data is waited.
       WaitTime = 1000,
       //Eop tells End Of Packet charachter.
       Eop = '\r'
    };
    bluetooth.Send("Hello World!", null);
    if (bluetooth.Receive(p))
    {
	reply = Convert.ToString(p.Reply);
    }
}
