1 Android + TIBBO + Socket 建國科技大學資管系 饒瑞佶

2 Socket Socket

3 開始前 TIBBO 需要設定 Socket on_sock_data_arrival()

4 ' 接收外界來的 SOCKET 資訊 sub on_sock_data_arrival() Dim command_data as string ' 完整控制命令 command_data = "" ' 初始化控制命令 while sock.rxlen > 0 command_data = command_data + sock.getdata(255) wend ' 依據 socket 收到的值做出 io 控制 if command_data <> "" then select case command_data case "/getconfig": pat.play("-g-g-g-",pl_pat_canint) 'feedback for ff=0 to 7 sock.num = ff sock.setdata("xxxx") sock.send sock.rxclear next ff case "/operatoron1": pat.play("-g-b-g-",pl_pat_canint) end sub end if case else: end select

5 NEW Android Project 使用 Android Studio 需要開啟權限 <uses-permission android:name="android.permission.internet"/>
