Bluetooth Radar – 100,000 Downloads

Almost a year ago I compete in Microsoft “Enter Island” competition, and wrote a WPF Tool called – Bluetooth Radar.

Bluetooth Radar is WPF 4.0 application built in Visual Studio 2010 (RTM) and based on 32feet.net shared source library.

I also got a review from “The Life Hacker” - http://lifehacker.com/5525364/bluetooth-radar-displays-bluetooth+enabled-devices-for-easy-location-and-file-transfer

And today I noticed that my application reached to 103,905 Downloads (303.82 downloads / day)

Enter Island – Bluetooth Radar = #1 Place

Three weeks ago I heard about the Enter Island competition and I have decide to compete and build the “Bluetooth Radar”.

If you are not familiar with Enter Island competition here what you had to do, first to be from Middle East or Africa and to do one of the following:

Publish a photo or a short video of your IT workspace on the contest’s Facebook page, publish any project you built with Visual Studio 2010 on the CodePlex <<<--- I built a WPF 4 project called –
Bluetooth Radar – Over than 6000 downloads in 22 days, and I got a
Reviewd from Life Hacker About Bluetooth Radar.

Last night I got the following email from Microsoft:

Dear ShaiR,
Thanks for your contribution and active participation in the “Enter The Island: IT’s The Best Job in the World” contest!
Microsoft Middle East and Africa team and myself would like to sincerely thank you for investing your time in it.
With the support of those people who downloaded you project more than 2000 times you took the #1 place in the competition.
So it’s my pleasure to announce you as 1 of those who will join the IT Community at Mauritius this May!

Thanks for the support.

Working With Bluetooth Devices Using C# – Part 2 (OBEX)

shair — Tue, 23 Jun 2009 13:17:28 GMT

Working With Bluetooth Devices Using C# – Part 2 (OBEX)

In my last post I talked about Working With Bluetooth Devices Using C# – Part 1

In this post I’ll show how to send file to bluetooth device.

To send file to a bluetooth device we need to use WebRequest but with obex format.

Download Demo Project

OBEX is an acronym that stands for OBject EXchange, mostly used in the communications technology field as a communications protocol. Because the Infrared Data Association maintains OBEX, it is also known as IrOBEX or Infrared OBEX – More About OBEX

First we have to find the device we want to send the file:

BluetoothClient bc = new BluetoothClient();

BluetoothDeviceInfo[] array = bc.DiscoverDevices();

int count = array.Length;

for (int i = 0; i < count; i++)

{

Device device = new Device(array[i]);

devices.Add(device);

}

and now using thread or background worker send the file using ObexWebRequest.

public class ObexWebRequest : WebRequest
    {
        public ObexWebRequest(Uri requestUri);
 
        public override long ContentLength { get; set; }
        public override string ContentType { get; set; }
        public override WebHeaderCollection Headers { get; set; }
        public override string Method { get; set; }
        public override IWebProxy Proxy { get; set; }
        public override Uri RequestUri { get; }
        public override int Timeout { get; set; }
 
        public override Stream GetRequestStream();
        public override WebResponse GetResponse();
        public void ReadFile(string fileName);
    }

And implement ObexWebResponse to get bluetooth device response.

Continue = 16,        Success = 32,        Created = 33,        Accepted = 34,        NonAuthorativeInformation = 35,        NoContent = 36,        ResetContent = 37,        PartialContent = 38,        MultipleChoices = 48,        MovedPermanently = 49,        MovedTemporarily = 50,        SeeOther = 51,        NotModified = 52,        UseProxy = 53,        BadRequest = 64,        Unauthorized = 65,        PaymentRequired = 66,        Forbidden = 67,        NotFound = 68,        BadMethod = 69,
        NotAcceptable = 70,        ProxyAuthenticationRequired = 71,        RequestTimeout = 72,        Conflict = 73,        Gone = 74,        LengthRequired = 75,        PreconditionFailed = 76,        RequestedEntityTooLarge = 77,        RequestedUrlTooLarge = 78,        UnsupportedMediaType = 79,        InternalServerError = 80,
        NotImplemented = 81,        BadGateway = 82,        ServiceUnavailable = 83,        GatewayTimeout = 84,        HttpVersionNotSupported = 85,        DatabaseFull = 96,        DatabaseLocked = 97,        Final = 128,

public class ObexWebResponse : WebResponse
    {
        public override long ContentLength { get; set; }
        public override string ContentType { get; set; }
        public override WebHeaderCollection Headers { get; }
        public ObexStatusCode StatusCode { get; }
 
        public override void Close();
        public override Stream GetResponseStream();
        public void WriteFile(string fileName);
    }

And this how it looks:

public static ObexStatusCode SendFile(BluetoothAddress address, string file_path)

{

string FileName = file_path.Substring(file_path.LastIndexOf("\\"));

Uri uri = new Uri("obex://" + address.ToString() + "/" + file_path);

ObexWebRequest request = new ObexWebRequest(uri);

request.ReadFile(file_path);

ObexWebResponse response = (ObexWebResponse)request.GetResponse();

response.Close();

return response.StatusCode;

}

Working With Bluetooth Devices Using C# – Part 1

shair — Sun, 21 Jun 2009 18:16:28 GMT

Working With Bluetooth Devices Using C# – Part 1

32feet.NET is a shared-source project to make personal area networking technologies such as Bluetooth, Infrared (IrDA) and more, easily accessible from .NET code.

Supports desktop, mobile or embedded systems. The project currently consists of the following libraries:-

Bluetooth
IrDA
Object Exchange

In this post I’ll show how to find Bluetooth devices using C# code.

Download Demo Project

First download 32Feet.net assemblies, the create new project and add those assemblies.

Add using for using InTheHand.Net.Sockets;

BluetoothClient bc = new BluetoothClient();

Use BluetoothClient to discover bluetooth devices:

public BluetoothDeviceInfo[] DiscoverDevices();
public BluetoothDeviceInfo[] DiscoverDevices(int maxDevices);
public BluetoothDeviceInfo[] DiscoverDevices(int maxDevices, bool authenticated, bool remembered, bool unknown);

*** DiscoverDevices takes about 20-30 seconds to complete.

List<Device> devices = new List<Device>();
BluetoothClient bc = new BluetoothClient();
BluetoothDeviceInfo[] array = bc.DiscoverDevices();
int count = array.Length;
for (int i = 0; i < count; i++)
{
    Device device = new Device(array[i]);
    devices.Add(device);
}

public class Device

{

public string DeviceName { get; set; }

public bool Authenticated { get; set; }

public bool Connected { get; set; }

public ushort Nap { get; set; }

public uint Sap { get; set; }

public DateTime LastSeen { get; set; }

public DateTime LastUsed { get; set; }

public bool Remembered { get; set; }

public Device(BluetoothDeviceInfo device_info)

{

this.Authenticated = device_info.Authenticated;

this.Connected = device_info.Connected;

this.DeviceName = device_info.DeviceName;

this.LastSeen = device_info.LastSeen;

this.LastUsed = device_info.LastUsed;

this.Nap = device_info.DeviceAddress.Nap;

this.Sap = device_info.DeviceAddress.Sap;

this.Remembered = device_info.Remembered;

}

public override string ToString()

{

return this.DeviceName;

}
