1. Only one socket service can be set to transparent transmission mode at a time.
2. If
<service_type>
is "TCP LISTENER",
<access_mode>
cannot be specified to transparent
transmission mode directly. When a remote client connects to this server,
AT+QSWTMD
can be used
to switch the incoming connection to transparent transmission mode.
2.3.5. AT+QICLOSE Close a Socket Service
This command closes a specified socket service. Depending on the network, it takes at most 10 seconds
(default value, can be modified by
<timeout>
) to return
OK
or
ERROR
after executing
AT+QICLOSE
.
Before the response is returned, other AT commands cannot be executed.
If
<service_type>
is "TCP LISTENER" or "UDP SERVICE", specify this parameter
as 0.
<local_port>
Integer type. Local port number. Range: 0
–65535.
If
<service_type>
is "TCP LISTENER" or "UDP SERVICE", this parameter must be
specified. Range: 1
–65535.
If
<service_type>
is "TCP" or "UDP", this parameter can be omitted and the
default value is 0. The local port will be assigned automatically if
<local_port>
is 0.
Otherwise the local port is assigned as specified.
<access_mode>
