Number of services using this Internet connection profile.
0...9
Local IP address of the Internet connection profile (empty if no address is associated yet).
Note
• Before opening a service profile based on a connection profile recently used, check with
AT^SICI
that the
previous connection was properly closed. If
AT^SICI
confirms that the connection profile is in
<conState>
0 (Down) the connection profile may be used again.
10.2.1 Checking Connection Profile Status
Assume the network connection is temporarily not available. (If URC presentation mode of network registration
is enabled the state is shown by the URC "
+CREG
: 2").
The network connection is temporarily not available but the Internet connection is still established, so the host
may decide to stop the data transfer to minimize the risk of losing data due to memory limitations.
After closing the service with
AT^SISC
:
<numServices>
(num)
<conAddr>
(str)
at^sici?
Query the current status of the connection profile.
^SICI: 1,2,1,"10.10.0.161"
One connection profile has been created at
<con-
ProfileId>
=1, and one service is opened using
this connection profile. The Internet connection is in
<conState>
=2 ("Up").
OK
at^sici?
Query once again the current status of the connec-
tion profile.
^SICI: 1,3,1,"10.10.0.161"
Parameter
<conState>
has changed to state "Lim-
ited up".
OK
at^sici?
Query once again the current status of the connec-
tion profile.
^SICI: 1,2,1,"10.10.0.161"
After re-establishing the network connection,
<con-
State>
reverts to state "Up".
OK
at^sici?
Query once again the current status of the connec-
tion profile.
^SICI: 1,2,0,"10.10.0.161"
Parameter
<numServices>
has decreased. The
bearer is still open because the service was closed
before expiry of the inactivity timeout "inactTO" of
AT^SICS
.
OK
at^sici?
Query again the current status.
^SICI: 1,0,0,"0.0.0.0"
The inactivity timeout "inactTO" of
AT^SICS
has
expired, therefore the bearer is closed now.
OK
