10 Commands for Internet Services
Internet service, also known as IPSTACK service, means the service of using the
TCP/IP protocol stack embedded in the MG323 to perform data services. The
Internet service allows the host to access the Internet more easily through AT
commands. This chapter describes all the AT commands that are covered by the
TCP/IP protocol.
Currently, the MG323 supports Internet services for the Socket client/server of TCP
and the Socket client of UDP only.
Only the URC mode is supported for Internet services.
The URC mode means that the Internet service process is driven by the URC. The
URC notifies the host of whether the data can be sent or received, whether data
transmission is complete, whether the service can be disabled, and whether an error
occurs.
