10.2 AT^SICI Internet Connection Information
Description: The AT^SICI read command requests the current status of the Internet connection profiles
currently defined with AT^SICS.
The AT^SICI write command displays the status of the specified Internet connection profile. If the
connection profile is not defined yet, the command returns a "+CME ERROR" response.
Syntax: Test Command: AT^SICI=?
Response: [^SICI: (list of defined <conProfileId>s)]
OK
Read Command: AT^SICI?
Response: [^SICI: <conProfileId>, <conState>, <numServices>, <conAddr>]
[^SICI: ...]
OK
Write Command: AT^SICI=<conProfileId>
Response: ^SICI: <conProfileId>, <conState>, <numServices>, <conAddr>
OK
ERROR
+CME ERROR: <err>
Parameters:
<conProfileId>
Internet connection profile identifier as defined by AT^SICS (<conProfileId>).
0...5
<conState>
State of the Internet connection profile.
0 Down - Internet connection is defined but not connected.
1 Connecting - A service has been opened and so the Internet connection is initiated.
2 Up - Internet connection is established and usable by one or more services.
3 Limited Up - Internet connection is established, but temporarily no network coverage.
This state applies only to GPRS profiles (it does not occur with CSD).
4 Closing - Internet connection is terminating.
<numServices>
Number of services using this Internet connection profile.
0...9
<conAddr>
Local IP address of the Internet connection profile (empty if no address is associated yet).
Notes:
• 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.
• This command is not PIN protected.
• This command is supported in airplane mode.
10.2.1 Checking Connection Profile Status
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
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").
at^sici? Query once again the current status of the connection profile.
^SICI: 1,3,1,"10.10.0.161" Parameter <conState> has changed to state "Limited up".
OK
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.
at^sici? Query once again the current status of the connection profile.
^SICI: 1,2,1,"10.10.0.161" After re-establishing the network connection, <con-State> reverts to
state "Up".
OK
