2.4.2. +QIURC: "recv" Indicate Incoming Data
In buffer access mode or direct push mode, after receiving data, the module reports a URC to the host.
In
buffer
access
mode,
after
receiving
data,
the
module
reports
+QIURC:
"recv",<connectID>[,<data_len>]
to notify the host. Then host can retrieve data with
AT+QIRD
. Please
note that if the buffer is not empty, and the module receives data again, it does not report a new URC until
all the received data has been retrieved with
AT+QIRD
from the buffer.
In direct push mode, the received data is outputted to COM port directly.
Parameter
2.4.3. +QIURC: "incoming full" Indicate Incoming Connection Reaches the Limit
If the number of incoming connections reaches the limit, or no socket system resources can be allocated,
the module reports
+QIURC: "incoming full"
for the new incoming connection request.
2.4.4. +QIURC: "incoming" Indicate Incoming Connection
If
<service_type>
is "TCP LISTENER", when a remote client connects to this server, the host
automatically assigns a free
<connectID>
to the new connection, and the range of
<connectID>
is 0
–11.
+QIURC: "recv" Indicate Incoming Data
+QIURC: "recv",<connectID>[,<data
_len>]
Indicating incoming data in buffer access mode. The host can
retrieve data with
AT+QIRD
.
+QIURC: "recv",<connectID>,<curre
ntrecvlength><CR><LF><data>
Indicating incoming data in direct push mode when the
<service_type>
is "TCP", "UDP" or "TCP INCOMING".
+QIURC: "recv",<connectID>,<curre
ntrecvlength>,<remoteIP>,<remote_
port><CR><LF><data>
Indicating data incoming in direct push mode when
<service_type>
is "UDP SERVICE".
<connectID>
Integer type. Socket service index. Range: 0
–11.
<data_len>
Integer type. Data length. Unit: byte.
<currentrecvlength>
Integer type. Length of actually received data.
<remoteIP>
String type. Remote IP address.
<remote_port>
Integer type. Remote port number.
<data>
String type. Received data.
+QIURC: "incoming full" Indicate Incoming Connection Reaches the Limit
+QIURC: "incoming full"
Indicating the number of incoming connections reaches the limit.
