Quectel BG96 TCP/IP User Manual

LPWA Module Series
BG96 TCP/IP Application Note
BG96_TCP/IP_Application_Note 34 / 52
In direct push mode, the received data will be outputted to COM port directly.
Parameter
2.3.3. +QIURC: "incoming full" Indicate Incoming Connection Full
If an incoming connection reaches the limit, or no socket system resources can be allocated, then the
module will report the URC +QIURC: "incoming full" for the new incoming connection request.
2.3.4. +QIURC: "incoming" Indicate Incoming Connection
If <service_type> is "TCP LISTENER", when a remote client connects to this server, the host will
automatically assign a free <connectID> for the new connection, and the range of <connectID> is 0–11.
In such a case, the module will report the URC +QIURC: "incoming". The <service_type> of the new
connection will be "TCP INCOMING", and the <access_mode> will be buffer access mode.
+QIURC: "recv" Indicate Incoming Data
+QIURC: "recv",<connectID>
Indicate incoming data in buffer access mode. The host can
retrieve data via AT+QIRD.
+QIURC: "recv",<connectID>,<curre
ntrecvlength><CR><LF><data>
Indicate incoming data in direct push mode when the
<service_type> is "TCP", "UDP" or "TCP INCOMING".
+QIURC: "recv",<connectID>,<curre
ntrecvlength>,<remoteIP>,<remote_p
ort><CR><LF><data>
Indicate incoming data in direct push mode when
<service_type> is "UDP SERVICE".
<connectID> Integer type. Socket service index. Range: 0–11.
<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 Full
+QIURC: "incoming full"
The URC indicates the incoming connection is full.
+QIURC: "incoming" Indicate Incoming Connection
+QIURC: "incoming",<connectID>,<s
erverID>,<remoteIP>,<remote_port>
When the new incoming connection is accepted by
<serverID>, the allocated <connectID>, <remoteIP> and
<remote_port> will be informed by this URC.
