<contextID> Integer type. Context ID. Range: 1–16.

2.3.4. AT+QIOPEN Open a Socket Service

This command opens a socket service. The service type can be specified by <service_type>. The data
access mode (buffer access mode, direct push mode and transparent transmission mode) can be
specified by <access_mode>. The response +QIOPEN: <connectID>,<result> indicates whether the
socket service has been opened successfully.
If <service_type> is " TCP LISTENER " , the module works as TCP server. After accepting a new TCP
1.
connection, the module automatically specifies a <connectID> and reports URC +QIURC:
"incoming",<connectID>,<serverID>,<remoteIP>,<remote_port>. The range of <connectID> is
0–11. The type of this new incoming connection is " TCP INCOMING " and the <access_mode> of
" TCP INCOMING " is the same with that of " TCP LISTENER " .
2. If <service_type> is "UDP SERVICE", UDP data can be sent to or received from the remote IP via
<local_port>.

Send data: execute AT+QISEND=<connectID>,<send_length>,<remoteIP>,<remote_port>.

Receive data
"recv",<connectID>,<currentrecvlength>,<remoteIP>,<remote_port><CR><LF><data>.

Receive data
"recv",<connectID>[,<data_len>], and then the received data can be retrieved with
AT+QIRD=<connectID>.
3. It is suggested to wait for 150 seconds for +QIOPEN: <connectID>,<result> to be outputted after
executing the Write Command. If the response cannot be received in 150 seconds, AT+QICLOSE
should be used to close the socket.
