3.5.7.4.7. Socket Open - #SKTOP

#SKTOP - Socket Open

AT#SKTOP Execution command activates the context number 1, proceeds with the

authentication with the user ID and password previously set by #USERID

and #PASSW commands, and opens a socket connection with the host

specified in the #SKTSET command. Eventually, before opening the socket

connection, it issues automatically a DNS query to solve the IP address of

the host name.

If the connection succeeds a CONNECT indication is sent, otherwise a NO

CARRIER indication is sent.

AT#SKTOP=? Test command returns the OK result code.

Example AT#SKTOP

..GPRS context activation, authentication and socket open..

CONNECT

Note This command is obsolete. It’s suggested to use the couple #SGACT and

#SD

instead of it.

3.5.7.4.8. Query DNS - #QDNS

#QDNS - Query DNS

AT#QDNS=

[<host name>]

Execution command executes a DNS query to solve the host name into an IP

address.

Parameter:

<host name> - host name, string type.

If the DNS query is successful then the IP address will be reported in the

result code:

#QDNS:"<host name>",<IP address>

Note: the command has to activate the GPRS context if it was not previously

activated. In this case the context is deactivated after the DNS query.

Note: <IP address> is in the format: xxx.xxx.xxx.xxx

AT#QDNS=? Test command returns the OK result code.

Note This command requires that the authentication parameters are correctly

set and that the GPRS network is present.
