c#读蓝牙数据,在C＃中从蓝牙设备获取数据
I'm trying to get data from a medical BT device that I already have pairing code and communication protocol.
Looking for some code I've got this code:
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();
}
}
}
}
And this is the console result:
While I expect something like 0XA5 0x05 0x04 0x01 etc. etc.
Can you help me to get the correct result?

You want to replace the following:
myCompleteMessage.AppendFormat("{0}", Encoding.ASCII.GetString(myReadBuffer, 0, numberOfBytesRead));
with
for (int i = 0; i < numberOfBytesRead; i++)
myCompleteMessage.AppendFormat("0x{0:X2} ", myReadBuffer[i]);
