�
The module has a TCP Socket. When the module in translate mode, to write the data of
the UART interface module, module will automatically send a Socket; Module through
the Socket received data, send out through the UART interface.
� Socket works include: the TCP Server, the TCP Client, UDP Client, and UDP Server,
please refer to the AT command set method in the AT + SOCKA instruction set or
through a web page Settings.
�
When a TCP Server Socket set, can support up to four TCP Client TCP link connection.
In a multiple TCP link connection mode, from the TCP transport data will be forwarded
to them one by one on the UART interface. Come from the UART interface data will be
copied into a more, in every TCP forwarding a link. Specific data flow diagram shown
below:
