我尝试通过蓝牙连接 arduino 和 Android，它工作得很好。但是在初始化连接时，我在我的 arduino 中编写了一个设置，我不知道如何调用它。
void setup() {
// put your setup code here, to run once:
Genotronex.begin(9600);
Genotronex.println("Bluetooth On please press 1 or 0 blink LED ..");
pinMode(ledpin,OUTPUT);
}
这是我在android中的代码
void beginListenForData()
{
final Handler handler = new Handler();
final byte delimiter = 10; //This is the ASCII code for a newline character
stopWorker = false;
readBufferPosition = 0;
readBuffer = new byte[1024];
workerThread = new Thread(new Runnable()
{
public void run()
{
while(!Thread.currentThread().isInterrupted() && !stopWorker)
{
try
{
int bytesAvailable = mmInputStream.available();
if(bytesAvailable > 0)
{
byte[] packetBytes = new byte[bytesAvailable];
mmInputStream.read(packetBytes);
for(int i=0;i<bytesAvailable;i++)
{
byte b = packetBytes[i];
if(b == delimiter)
{
byte[] encodedBytes = new byte[readBufferPosition];
System.arraycopy(readBuffer, 0, encodedBytes, 0, encodedBytes.length);
final String data = new String(encodedBytes, "US-ASCII");
readBufferPosition = 0;
handler.post(new Runnable()
{
public void run()
{
myLabel.setText(data);
}
});
}
else
{
readBuffer[readBufferPosition++] = b;
}
}
}
}
catch (IOException ex)
{
stopWorker = true;
}
}
}
});
workerThread.start();
}
帮我出来。我真正想要的是当我从android打开连接时它应该显示Bluetooth On please press 1 or 0 blink LED..如果我设置了计时器，如何在我的android中做监听器。
