In Multi-IP state:
0 IP INITIAL
1 IP START
2 IP CONFIG
3 IP GPRSACT
4 IP STATUS
5 IP PROCESSING
9 PDP DEACT
Parameter Saving NO_SAVE
Mode
Max Response When mode is multi-IP state, the max response time75 seconds.
Time When mode is single state, and the state is IP INITIAL, the max response
time is 160 seconds.
Reference Note
This command allows establishment of a TCP/UDP connection only when
the state is IP INITIAL or IP STATUS when it is in single state. In
multi-IP state, the state is in IP STATUS only. So it is necessary to process
"AT+CIPSHUT" before user establishes a TCP/UDP connection with this
command when the state is not IP INITIAL or IP STATUS.
When module is in multi-IP state, before this command is executed, it is
necessary to process "AT+CSTT, AT+CIICR, AT+CIFSR".
