Internal Protocol Stack Application Scenarios
Solution
Initialization has not been performed.
Initialize the internal protocol stack and
query again.
Initialization failed.
1. Check that the current network signal
strength is good and the parameters are
set correctly.
2. Ensure that no IP stack termination
command has been executed.
AT^IPINIT? queries whether the internal
protocol stack has been initialized. If the
internal protocol stack has been
initialized, it does not need to be
initialized again. If it has not been
initialized, there are ongoing dial-up
services. Hang up the dial-up services
and re-send ^IPINIT to start initialization.
Description
Initialize the internal protocol stack.
Create a TCP server whose listen port
number is 5000 (users can specify this
number as required). For the method
to create UDP servers, refer to the AT
command document.
Query the information about the server
that has been created.
