Set command opens the socket towards the peer specified in the parameters.
Parameters:
<socket type> - socket protocol type
0 - TCP (factory default)
1 - UDP
<remote port> - remote host port to be opened
1..65535 - port number
<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 when remote host has closed (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
1..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 #SKTD command, then an error message will
be issued.
Note: the command 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
- the GPRS has been activated with AT#GPRS=1
Note: this command is not allowed for sockets associated to a GSM context (see
#SCFG).
