Max Response
Time
When mode is multi-IP state, the max response time75 seconds.
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".
