BG96 TCP/IP Application Note
//Context is 1 and <connectID> is 0.
Before using AT+QIOPEN, the host should
activate the context with AT+QIACT first.
//TCP client is connected successfully. It is
suggested to wait for 150 seconds for the
URC +QIOPEN: <connectID>,<err>. If the
URC cannot be received in 150 seconds,
the host can use AT+QICLOSE to close the
socket.
//Query the connection status of socket
service 1.
