大佬好，我运行Demo后，发现可以submit和重连，但是收不到返回的cmppSubmitMsg，正常么？

[guoliwei139]

` CmppMessageHeader submit = new CmppSubmit(Command.CMPP2_VERSION, serviceId, srcId, sequenceId, mobile, content);

    client.submit(submit);`

我用这一步提交完短信后，CMPPHandler这个handler的channelRead0()方法始终收不到cmpp返回的cmppSubmitResp，就是这样的么？ 这是打印出的日志： 初始化创建连接。。。 -------------请求连接应答------------- 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 心跳启动!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
