C# bluetooth file send.
- by cheesebunz
i'm new to bluetooth development and i found the 32netfeet . Right now i'm able to search for bluetooth devices nearby and connect to them but how do i send a file e.g SendTest.txt? I tried buttonclick event using the OBEX but i don't understand this is my example code:
using InTheHand.Net;
using InTheHand.Net.Sockets;
using InTheHand.Net.Bluetooth;
namespace BluetoothIntheHand
{
public partial class Form2 : Form
{
private Guid service = BluetoothService.DialupNetworking;
private BluetoothClient bluetoothClient;
public Form2()
{
InitializeComponent();
}
private void btnSearch_Click(object sender, EventArgs e)
{
BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;
BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio;
lblSearch.Text = "" + myRadio.LocalAddress.ToString();
bluetoothClient = new BluetoothClient();
Cursor.Current = Cursors.WaitCursor;
BluetoothDeviceInfo[] bluetoothDeviceInfo = { };
bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10);
comboBox1.DataSource = bluetoothDeviceInfo;
comboBox1.DisplayMember = "DeviceName";
comboBox1.ValueMember = "DeviceAddress";
comboBox1.Focus();
Cursor.Current = Cursors.Default;
}
private void btnConnect_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedValue != null)
{
try
{
bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service));
MessageBox.Show("Connected");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
private void btnSend_Click(object sender, EventArgs e)
{
bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service));
String addr = "112233445566";
Uri uri = new Uri("obex://"+@"SendTest.txt");
ObexWebRequest req= new ObexWebRequest(uri);
ObexWebResponse rsp;
}
I found the guide but don't really knw hw to convert to C#
' The host part of the URI is the device address, e.g. IrDAAddress.ToString(),
' and the file part is the OBEX object name.
Dim addr As String = "112233445566"
Dim uri As New Uri("obex://" & addr & "/HelloWorld2.txt")
Dim req As New ObexWebRequest(uri)
Using content As Stream = req.GetRequestStream()
' Using a StreamWriter to write text to the stream...
Using wtr As New StreamWriter(content)
wtr.WriteLine("Hello World GetRequestStream")
wtr.WriteLine("Hello World GetRequestStream 2")
wtr.Flush()
' Set the Length header value
req.ContentLength = content.Length
End Using
' In this case closing the StreamWriter also closed the Stream, but ...
End Using
Dim rsp As ObexWebResponse = CType(req.GetResponse(),ObexWebResponse)
Console.WriteLine("Response Code: {0} (0x{0:X})", rsp.StatusCode)
