C# - How to scan for Bluetooth devices (using 32feet.NET)

Hi again!

I received a comment from a friend about if it possible to scan for Bluetooth devices using C#. So I started the research looking for options and then I found “32feet.NET”. You can read the full description and download the project here:

#setup

Follow the steps described in the page and install the project. After this, make sure the Bluetooth port is turned on in your computer

#codeTime!

Add a dataGridView and a button to your Form. Then adapt the following code to a VS project:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using InTheHand.Net.Bluetooth;

using InTheHand.Net.Sockets;

using InTheHand.Net;

using System.IO;

namespace BT

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)

        {

            scan();

        }

        private void scan()

        {

            BluetoothRadio.PrimaryRadio.Mode = RadioMode.Connectable;

            BluetoothClient client = new BluetoothClient();

            BluetoothDeviceInfo[] devices = client.DiscoverDevices();

            BluetoothClient bluetoothClient = new BluetoothClient();

            String authenticated;

            String classOfDevice;

            String connected;

            String deviceAddress;

            String deviceName;

            String installedServices;

            String lastSeen;

            String lastUsed;

            String remembered;

            String rssi;

            foreach (BluetoothDeviceInfo device in devices)

            {

                authenticated = device.Authenticated.ToString();

                classOfDevice = device.ClassOfDevice.ToString();

                connected = device.Connected.ToString();

                deviceAddress = device.DeviceAddress.ToString();

                deviceName = device.DeviceName.ToString();

                installedServices = device.InstalledServices.ToString();

                lastSeen = device.LastSeen.ToString();

                lastUsed = device.LastUsed.ToString();

                remembered = device.Remembered.ToString();

                rssi = device.Rssi.ToString();

                string[] row = new string[] { authenticated, classOfDevice, connected, deviceAddress, deviceName, installedServices, lastSeen, lastUsed, remembered, rssi };

                dataGridView1.Rows.Add(row);

            }

        }

    }

}

Click your “Scan” button and wait for few seconds to get data in your dataGridView. This is my working result showing my phone’s details:

Enjoy!
