#SKTSET - Socket Definition
<remote port> - remote host port to be opened
0..65535 - port number (factory default is 3333)
<remote addr> - address of the remote host, string type. This parameter can be
either:
- any valid IP address in the format: xxx.xxx.xxx.xxx
- any host name to be solved with a DNS query in the format: <host name>
(factory default is the empty string “”)
<closure type> - socket closure behaviour for TCP when remote host has closed
0 - local host closes immediately (default)
255 - local host closes after an escape sequence (+++) or immediately in case of an
abortive disconnect from remote.
<local port> - local host port to be used on UDP socket
0..65535 - port number
Note: <closure type>
parameter is valid only for TCP socket type, for UDP sockets
shall be left unused.
Note: <local port> parameter is valid only for UDP socket type, for TCP sockets
shall be left unused.
Note: The resolution of the host name is done when opening the socket, therefore if
an invalid host name is given to the #SKTSET command, then an error message
will be issued.
Note: the DNS Query to be successful requests that:
- the GPRS context 1 is correctly set with +CGDCONT
- the authentication parameters are set (#USERID, #PASSW)
- the GPRS coverage is enough to permit a connection.
Note: this command is not allowed for sockets associated to a GSM context (see
Read command reports the socket parameters values, in the format:
AT#SKTSET: <socket type>,<remote port>,<remote addr>,
<closure type>,<local port>
Test command returns the allowed values for the parameters.
AT#SKTSET=0,1024,"123.255.020.001"
OK
AT#SKTSET=0,1024,"www.telit.net"
Issuing command #QDNS will overwrite <remote addr> setting.
