+MIPCFF, Control Filtering Feature for Incoming TCP Connection

This AT command is used to control filtering feature. Filtering feature adds the ability to accept

IP connections only if the IP belongs to a defined IP white list to the embedded TCP/IP feature.

This feature affects only TCP socket type connections.

Command Type Syntax Response/Action Remarks

Set

AT+MIPCFF=

<SocketID>,<CmdType>[,"<

IP CIDR>"]

or:

+CME ERROR: <err>

The set command

defines the IP

white list and

controls the

feature behavior

(enable or

disable).

If <CmdType> is

0, 1 or 4, then <IP

CIDR> parameter

is not allowed.

If <IP CIDR>

parameter will be

present in that

case, the error

message will be

returned to DTE.

If <CmdType> is 2

(add IP to white

list) or 3 (remove

IP from white list),

the <IP CIDR>

parameter is

mandatory.

Read

AT+MIPCFF? +MIPCFF:

1,<Status>,<IP1.1>,<IP1.2>…<I

P1.n>

+MIPCFF:

2,<Status>,<IP2.1>,<IP2.2>…<I

P2.n>

+MIPCFF:

3,<Status>,<IP3.1>,<IP3.2>…<I

P3.n>

+MIPCFF:

4,<Status>,<IP4.1>,<IP4.2>…<I

P4.n>

or:

+CME ERROR: <err>

For each socket

the command

returns the current

filtering feature

state (enabled,

disabled or not

applicable) and a

list of IP addresses

(in CIDR notation)

in socket filtering

white list.

In case the

connection is set

for "client"

functionality

(socket initiates

the connection)

the filtering status

is 2 ("not

applicable").

Test

AT+MIPCFF =? +MIPCFF: (1-4),(0-4),("<IP

CIDR>")

or:

+CME ERROR: <err>

The command

returns the range

of <SocketID>'s,

the list of

supported

<CmdType>'s and

string "<IP

CIDR>".
