AT+SCA<field>=<matching-text>
The <field> is the field within the certificate, and may be one of the following values:
C: Country
S: State
L: Locality
O: Organization
OU: Organizational Unit
CN: Common Name
EM: Email Address
The <matching-text> is a literal string with the addition of three tokens: %h which means the hostname of the
remote peer, %i which means the IP Address of the remote peer. If the <matching-text> is omitted, then the field
is not validated (note that once a field is set via this command, the only way to revert the setting back to the GUI
specification is to reset the modem via ATZ or AT&F, which reverts all of the settings). For example, to validate
the Organization as “Tactical Software”, and the Common Name as the hostname of the server, the application
sends the following commands:
AT+SCAO=Tactical Software
OK
AT+SCACN=%h
OK
The application may query the current setting of each field, as shown in the example below:
AT+SCAO?
Tactical Software
OK
AT+SCACN?
%h
OK
The application may also query the contents of each field of the certificate presented from the peer in the last
SSL/TLS session. For example:
AT+SCEM=?
OK
AT+SCACN=?
