从C＃中的蓝牙设备获取数据

我正在尝试从医疗BT设备获取数据，我已经配对了代码和通信协议。

寻找一些代码，我有这个代码：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using InTheHand.Net.Sockets; using InTheHand.Net; using InTheHand.Net.Bluetooth; using InTheHand.Windows.Forms; using System.Net.Sockets; using System.Diagnostics; using System.Threading; namespace dConsoleApp { static class Program { // My BT USB adapter private static BluetoothEndPoint EP = new BluetoothEndPoint(BluetoothAddress.Parse("00:02:72:CD:9A:33"), BluetoothService.BluetoothBase); private static BluetoothClient BC = new BluetoothClient(EP); // The BT device that would connect private static BluetoothDeviceInfo BTDevice = new BluetoothDeviceInfo(BluetoothAddress.Parse("94:21:97:60:07:C0")); private static NetworkStream stream = null; static void Main(string[] args) { if (BluetoothSecurity.PairRequest(BTDevice.DeviceAddress, MY_PAIRING_CODE)) { Console.WriteLine("PairRequest: OK"); if (BTDevice.Authenticated) { Console.WriteLine("Authenticated: OK"); BC.SetPin(MY_PAIRING_CODE); BC.BeginConnect(BTDevice.DeviceAddress, BluetoothService.SerialPort, new AsyncCallback(Connect), BTDevice); } else { Console.WriteLine("Authenticated: No"); } } else { Console.WriteLine("PairRequest: No"); } Console.ReadLine(); } private static void Connect(IAsyncResult result) { if (result.IsCompleted) { // client is connected now :) Console.WriteLine(BC.Connected); stream = BC.GetStream(); if (stream.CanRead) { byte[] myReadBuffer = new byte[1024]; StringBuilder myCompleteMessage = new StringBuilder(); int numberOfBytesRead = 0; // Incoming message may be larger than the buffer size. do { numberOfBytesRead = stream.Read(myReadBuffer, 0, myReadBuffer.Length); myCompleteMessage.AppendFormat("{0}", Encoding.ASCII.GetString(myReadBuffer, 0, numberOfBytesRead)); } while (stream.DataAvailable); // Print out the received message to the console. Console.WriteLine("You received the following message : " + myCompleteMessage); } else { Console.WriteLine("Sorry. You cannot read from this NetworkStream."); } Console.ReadLine(); } } } 

}

这是控制台结果：

虽然我期待像0XA5 0x05 0x04 0x01等等。

你能帮我找到正确的结果吗？

您想要替换以下内容：

 myCompleteMessage.AppendFormat("{0}", Encoding.ASCII.GetString(myReadBuffer, 0, numberOfBytesRead)); 

同

 for (int i = 0; i < numberOfBytesRead; i++) myCompleteMessage.AppendFormat("0x{0:X2} ", myReadBuffer[i]);
