c# - 我如何使用 c# 连接多个具有蓝牙技术的设备

Question

我尝试使用蓝牙将两台以上的设备连接到一台设备，如果我在 c# 中编程，最好的方法是什么？

public BluetoothDeviceInfo[] DiscoverDevices();

Answer 1

您可以获得可用设备的数量，然后使用 BluetoothClient 类遍历所有设备的 List:

int maxDevices = 10;
List<Device> devices = new List<Device>();
BluetoothClient bc = new BluetoothClient();
BluetoothDeviceInfo[] array = bc.DiscoverDevices(maxDevices);
int count = array.Length;
for (int i = 0; i < count; i++)
{
    Device device = new Device(array[i]);
    devices.Add(device);

    // the variable device will now hold a detected BT device.
    // Now you can connect to the device:
    bc.Connect(new BluetoothEndPoint((BluetoothAddress)adres,service));

    // Send a message to the device
    System.Net.Sockets.NetworkStream stream = bc.GetStream();
    StreamWriter streamWriter = new StreamWriter(stream);
    streamWriter.WriteLine("! 0 200 200 210 1");
}
// the variable devices will now hold an array of all detected BT devices.

注意:DiscoverDevices 大约需要 20-30 秒才能完成。
