我正在制作一个使用套接字将消息发送到硬件(arduino)的应用程序,但是我无法收到任何消息吗?
new Thread(new Runnable() {
@Override
public void run() {
try {
client = new Socket(ipAddress, portNumber);
printwriter = new OutputStreamWriter(client
.getOutputStream(), "ISO-8859-1");enter code here
printwriter.write(message);
printwriter.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(client.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
line = br.readLine();
}
Toast.makeText(getBaseContext(),line,Toast.LENGTH_SHORT).show();
printwriter.close();
client.close();
}
catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
t.setText("done");
发生的情况是,当我发送消息时,它会打印在arduion上,但是当arduion发送回消息时,我在数据包跟踪器应用程序中看到它实际上是在发送数据包,但是我的应用程序没有捕获并将其放入吐司面包
