Re: [問題] 藍芽接值 掉值問題
※ 引述《fake01 (code)》之銘言：
: 使用手機藍芽接值,而接的值是由硬體端不斷丟值,
: 通常一秒丟一串字串 例如 123$456# or 455$123$
: 但是藍芽這邊接一次有時候會漏掉值 123456# 或 123$56，
: 但有時候又會正常接,是無法判斷硬體這邊丟一次的字串是甚麼，
: 請問該如何解決呢
: case MESSAGE_READ:
: byte[] readBuf = (byte[]) msg.obj;
: // construct a string from the valid bytes in the buffer
: String readMessage = null;
: try {
: readMessage = new String(readBuf, 0,msg.arg1,"GBK");
: }
: catch (UnsupportedEncodingException e)
: {
: // TODO Auto-generated catch block
: e.printStackTrace();
: }
: break;
: // 以上就是藍芽抓值的code,麻煩各位了
因為C大說貼socket部分的code
會比較好懂，我是用Chat? 那個藍芽範例所改的應該沒甚麼問題
private class ConnectedThread extends Thread {
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;
public ConnectedThread(BluetoothSocket socket) {
Log.d(TAG, "create ConnectedThread");
mmSocket = socket;
InputStream tmpIn = null;
OutputStream tmpOut = null;
// Get the BluetoothSocket input and output streams
try {
tmpIn = socket.getInputStream();
tmpOut = socket.getOutputStream();
} catch (IOException e) {
Log.e(TAG, "temp sockets not created", e);
}
mmInStream = tmpIn;
mmOutStream = tmpOut;
}
public void run() {
Log.i(TAG, "BEGIN mConnectedThread");
byte[] buffer = new byte[1024];
int bytes;
// Keep listening to the InputStream while connected
while (true) {
try {
// Read from the InputStream
bytes = mmInStream.read(buffer);
// Send the obtained bytes to the UI Activity
mHandler.obtainMessage(TestbtActivity.MESSAGE_READ,
bytes, -1, buffer)
.sendToTarget();
} catch (IOException e) {
Log.e(TAG, "disconnected", e);
connectionLost();
break;
}
}
}
