HTTPD Client of Ethernet module USR-TCP232-T2

Httpd Client

1) In this mode, the user's terminal device can send request data to the specified HTTP server through T2, and then T2 receives from HTTP. The server's data, parses the data and sends the results to the serial device.
 
2) The user does not need to pay attention to the data conversion process between the serial port data and the network data packet, and the serial port setting can be realized by simple parameter setting. A data request to the HTTP server.
 
3) When T2 sends data to the HTTP server through the serial port, the required URL and header, target domain name/IP, target port number, etc. can be passed.
Saved after T2 setting, only need to send request data every time data is sent, T2 will automatically add informat ion such as URL and header. Returned data, The user can choose whether to go to the header processing.
 
4) Specific use cases
