Q:通过WebApi接口UnificationSend向设备发送消息后,返回值只指明了是否发送成功,怎么取回设备返回的消息呢?比如发送0x8801后,设备返回0x0805,客户端怎么能拿到这个0x0805消息呢?
大佬,接收平台方转发数据这里貌似有坑,目前有两种情况:1、连接正常情况下,对方IP端口不变,断开连接后调用item.ReceiveTimeout.Cancel()无效,超过10分钟的会话仍然存在,必须调用SessionManager.RemoveByTerminalPhoneNo方法才能移除该会话,不调用则必须重启服务,否则无法再次上线,重启服务之后也不能立即上线,需要最长10分钟才能上线。
2、对方IP不变端口一直在变,会话中存在多条该终端号记录,其中包含相同的IP端口数据,也有不同的端口。每台设备平均每10秒钟打印一条JT808SessionOnline日志。
JT808SessionManager.TerminalPhoneNoSessions数量为1500,JT808SessionManager.Sessions数量超过10万,不重启服务会话数量会一直增长,内存也随之不断增长。
编译完毕后,运行 JT808.Gateway.SimpleServer.exe 时出现下面的错误:
fail: JT808.Gateway.Transmit.JT808TransmitService[0]
该终端all已尝试未连接上该服务器127.0.0.1:20000
System.Net.Sockets.SocketException (10061): 由于目标计算机积极拒绝,无法连接。
这个监听20000端口的是哪个程序?怎么启动?
windows环境下使用kafka队列接入1200多台终端,QueueServerHosting占用内存会越来越大,大概每秒0.1M的速度增长,直至占用内存100%,始终找不到是哪出问题了
你好,808服务端能获取到设备的ip吗?
作者你好!看了你的项目觉得做得很好,可以联系吗?
Pipeline DotNetty性能方面有差异吗?
Unhandled exception. System.Net.Sockets.SocketException (13): Permission denied
部标2019版本已经发布,请问后续是否有支持2019版本的计划?

对于某些GPS设备发送的非808协议数据用该网关怎么处理呢?网关可以改造么,谢谢
大神,基于JT808DotNetty做主动安全的协议,里面的附件上传是码流方式,和信令是一个通道。原本想做一个拓展库,发现 AddJT808TcpNettyHost 这个方法里面用到类很多是internal。我想做的是在解码中再插入一个分隔符“0x30 0x31 0x63 0x64”,现在看来只有修改源码了吗?

自定义了 5808 5000 端口都EXPOSE 了
1、gps数据通过此网关处理后,怎么通过websocket将接收到的GPS位置数据广播到所有html5页面中,h5中通过websocket获取位置数据后立刻更新位置。
2、此网关服务实例怎么扩展自定义接收到的消息呢?不是标准的808协议
大神,JT808.DotNetty.Transmit 这个不开源吗,我在源码中没找到。
Dears,
Great project,now I can build this project on Ubuntu arm64 platform, but encounter below error when I run the JT808.Gateway.SimpleServer, could you give me some help or hints to fix it, sorry for this naive problem.

请问如何使平台主动给设备下发指令? 比如主动下发 终端属性查询指令
Pipeline版本怎么集成LengthFieldBasedFrameDecoder协议,调试代码的时候发现不是正确包的时候,抛出了相关异常,下次再发数据包时就进入了Write了,然后就断开了连接,是为什么呢?
JT808.DotNetty.SimpleClient 好像不能用哎
你好作者,我用了你部分代码监听GPS设备(DotNetty TCP协议),一台设备接入的时候正常接收信息,但是当2台以上GPS 设备通讯的时候 就会出现DotNetty 主动断开Channel 的情况,这时候GPS 设备又会重新连接(重新注册、鉴权)。 这种情况会频繁出现。
我通过日志看到是先走了 CloseAsync函数 (您在注释中说是 server端主动断开)。想请您看看我的代码帮我分析一下问题(有偿)。
WX号:15141173250. 希望得到你的帮助。
对于启动已配置好的端口的监听服务, 有单独控制器启动,暂停,结束的功能吗?
比如想集成到windows服务中运行, 在服务启动停止的时候对服务进行控制
若在接收JT808包中,有一个是非JT808包,会导致异常后,无法继续接收后面正常的JT808包。经查错误代码如下:
JT808TcpServer.cs(207行)
//if (beginMark != JT808Package.BeginFlag) throw new ArgumentException("Not JT808 Packages." + "[" + beginMark.ToString() + "]");
if (beginMark != JT808Package.BeginFlag)
{
totalConsumed = seqReader.Length;
seqReader.Advance(seqReader.Length);
}
另外,若MessageHandler处理出现异常也会出现无法继续接收下个JT808包的情况。目前 ,我是在MessageHandlertry-catch所有异常,不再向上抛。
