Android App 发送一个字节到 Arduino 董事会
原标题:Android App to send one byte to Arduino board

我有一个Android App的例子,我用Eclipse编集,安装在我的Android平板板上。它建立我的平板电脑和Arduino板块之间的通讯。

It is an example program from this link: "Seeeduino Demo - Android App" on this URL: http://www.seeedstudio.com/wiki/index.php?title=Seeeduino_ADK_Main_Board

有一节只是从我的平板板上 寄一个字节给Arduino董事会。

byte data;
data=1;
server.send(new byte[] {(byte) data});

它起作用了, 但是它除了一个字节外还发送了其它字节。 我需要了解这个服务器的功能是如何运作的。 send () 函数, 但我在 Android 引用中找不到关于它的任何信息 。

有人能指给我一个覆盖服务器. send () 函数的引用吗? 我想一次发送一个字节, 而不是其他字节 。

最佳回答

我快速查看了MicroBridge的来源。 以下是 < code> send 方法的工作部分:

    public void send(byte[] data) throws IOException
      {
              try {
                      output.write(data);
                      output.flush();
              } catch (SocketException ex)
              {
                      // Broken socket, disconnect
                      close();
                      server.disconnectClient(this);
              }
      }   

我想说管道里有数据, 正在被写入 output.flush ()
