Java Socket处于活动状态5分钟后关闭

Question

I have a active connection and I am sending and receiving data between client and server. The server is an OBD2 Wifi Dongle.

Everything is working fine but the socket closed exactly after 5 minutes. There is no inactivity. I am constantly communicating with the server.

Do you have any ideas? Or does it seems that OBD Dongle is closing the connection? Because it always ecaxtly after 5 minutes

Answer 1

只需发送一个心跳信号，例如3E每5秒钟发送一次-这意味着“ TESTER PRESENT”，使套接字保持活动状态，实际上无论如何是某些车辆协议的要求。
