Parameters

<n>                 

0..7     A numeric parameter which indicates the connection number

<mode>     A string parameter which indicates the connection type

“TCP”     Establish a TCP connection

“UDP”     Establish a UDP connection

<IP address>     A string parameter which indicates remote server IP address

<port>     Remote server port

<domain name>     A string parameter which indicates remote server domain name

<state>     A string parameter which indicates the progress of connecting

0     IP INITIAL

1     IP START

2     IP CONFIG

3     IP GPRSACT

4     IP STATUS

5     TCP CONNECTING/UDP CONNECTING/SERVER LISTENING

6     CONNECT OK

7     TCP CLOSING/UDP CLOSING

8     TCP CLOSED/UDP CLOSED

9     PDP DEACT

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

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.

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“.

the TCP or UDP connection that has been established already.

Ctrl-Z is used as a termination symbol. ESC is used to cancel sending data.

There are at most <size> bytes which can be sent at a time.

Note

The data length which can be sent depends on network status.

Set the time that send data automatically with the Command of AT+CIPATS.

Only send data at the status of established connection.

+CIPQSEND: (0,1)

0     Normal mode – when the server receives TCP data, it will response SEND OK.

1     Quick send mode – when the data is sent to module, it will response

DATA ACCEPT: <length> (For single IP connection (+CIPMUX=0)) or

DATA ACCEPT: <n>,<length> (For multi IP connection (+CIPMUX=1))

while not responding SEND OK.

+CIPACK: <txlen>,<acklen>,<nacklen>

OK

Parameters

<n>     A numeric parameter which indicates the connection number

<txlen>     The data amount which has been sent

<acklen>     The data amount confirmed successfully by the server

<nacklen>     The data amount without confirmation by the server

+CIPACK: <txlen>,<acklen>,<nacklen>

Parameters

See Write Command

W)

1) If single IP connection (+CIPMUX=0) AT+CIPCLOSE=<n>

2)   If multi IP connection (+CIPMUX=1)

1)   For single IP connection (+CIPMUX=0)

CLOSE OK

2)   For multi IP connection (+CIPMUX=1)

<id>,CLOSE OK

Parameters

<n>      

0     Slow close

1     Quick close

<id>     A numeric parameter which indicates the connection number

If close is successfully:

CLOSE OK

If close fails:

ERROR

Note

AT+CIPCLOSE only closes connection at corresponding status of TCP/UDP stack.

To see the status use AT+CIPSTATUS command.

Status should be: TCP CONNECTING, UDP CONNECTING, SERVER LISTENING or

CONNECT OK in single-connection mode (see <state> parameter);

CONNECTING or CONNECTED in multi-connection mode (see <client state>);

OPENING or LISTENING in multi-connection mode (see <server state>).

Otherwise it will return “ERROR”.

If close is successful:

SHUT OK

If close fails:

ERROR

Note

If this command is executed in multi-connection mode, all of the IP connection will be shut.

User can close gprs pdp context by AT+CIPSHUT.

After it is closed, the status is IP INITIAL.

If “+PDP: DEACT” urc is reported which means the gprs is released by the network, then user still needs to

execute “AT+CIPSHUT” command to make PDP context come back to original state.
