我试图将GPS数据发送到特定的服务器端口已经听取了协议。

AdmProtocolTester.java

这是要发送到服务器端口的实际数据，而不是使用Junit Test I尝试使用单独的Java GPS模拟应用程序发送数据。

public void testDecode（）抛出异常{

        AdmProtocolDecoder decoder = new AdmProtocolDecoder(new AdmProtocol());

        verifyNull(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "010042033836313331313030323639343838320501000000000000000000000000000000000000000000000000000000000000000000000000000000000000000073"));

        verifyPosition(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "01002680336510002062A34C423DCF8E42A50B1700005801140767E30F568F2534107D220000"));

        verifyPosition(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "010022003300072020000000000000000044062A330000000000107F10565D4A8310"));

        verifyPosition(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "0100268033641080207AA34C424CCF8E4239030800005B01140755E30F560000F00F70220000"));

        verifyPosition(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "01002680336510002062A34C423DCF8E42A50B1700005801140767E30F568F2534107D220000"));

        verifyPosition(decoder, binary(ByteOrder.LITTLE_ENDIAN,
                "01002200333508202000000000000000007F0D9F030000000000E39A1056E24A8210"));

我试图通过控制台发送值，但我无法通过以下行发送，如果我错过了任何内容，请你帮助我

（（Channel）channelFuture）.write（in.readLine（）+＆＃34; \ r \ n＆＃34;）;

端口 5092 是服务器侦听 AdmProtocol 的地方。
