Chengdu Ebyte Electronic Technology Co.,Ltd E810-DTU(CAN-ETH) User ManualCopyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd 214.1.8. TCP Server function(1)In TCP Server mode, E810-DTU (CAN-ETH) monitors the local port, accepts and establishes a connection fordata communication when a connection request is sent.When the E810-DTU (CAN-ETH) serial port receives the data, itwill send the data to all the client devices connected to the E810-DTU (CAN-ETH) at the same time.(2)It usually used for communication with TCP client in LAN and suitable for scenarios where there are no serversin the LAN and there are multiple computers or mobile phones requesting data from the server. Like TCP Client, thereare connections and disconnections to ensure reliable data exchange.(3) When E810-DTU (CAN-ETH) is used as the TCP Server, it can accept up to 6 Client connections (the number ofconnections can be customized). The local port number is a fixed value and cannot be set to 0.(4)TCP Server can set the maximum number of connections. When the maximum number of connections is reached,you can choose to kick off the old connection or disable the new connection function according to the instructionconfiguration.4.1.9. UDP Client function(1)UDP Client is a connectionless transmission protocol, which provides simple and unreliable transaction-orientedinformation transmission service. There is no connection establishment and disconnection. It only needs to establish IPand port to send data to each other.It is usually used for data transmission scenarios where the packet loss rate is not
