#SSLD – Opens a socket SSL to a remote server
Note: if timeout is not set for SSL connection the default timeout value, set by
AT#SSLCFG, is used.
Note: in online mode the socket is closed after an inactivity period (configurable
with #SSLCFG, with a default value of 90 seconds), and the
‘NO CARRIER’ message is printed.
Note: in online mode data is transmitted as soon as the data packet size is reached
or as after a transmission timeout. Both these parameters are configurable by using
#SSLCFG
Note: Before opening a SSL connection, make sure to have stored the needed
secure data (Certificate, CA certificate, private key), using AT#SSLSECDATA,
for the security level set through AT#SSLSECCFG.
Note: Before opening a SSL connection the GPRS context must have been
activated by AT#SGACT=x,1
Note: The PDP context definition that will be used, is set by AT#SSLCFG
