Data commands
Using AT Commands during a data connection
To use AT Commands during a data connection (e.g. while the product is in online
mode), it is necessary either to switch to offline mode, or to use the specific +WMUX
command to enable Commands / Data multiplexing.
Switch from online to offline mode
To switch from online mode to offline mode, the “+++” sequence must be sent.
Following this, the product gets back to offline mode with an “OK” response, and a AT
command can be sent.
NOTE:
The “+++” sequence will only work with the +ICF command using one of the following
settings:
• 8 data bits, with no parity
• 7 data bits, with even parity
Switch from offline to online mode
See the ATO command description.
+CBST – Bearer type selection
Description:
This command applies to both outgoing and incoming data calls, but in a different way.
For an outgoing call, the two parameters (e.g. <speed> and <ce>) are meaningful, where-
as for an incoming call, only the <ce> parameter is used.
NOTE:
1: For incoming calls, if <ce> is set to ‘T’ only and the network offers only ‘NT’ or vice
versa, then the call is released.
2: Values 2 and 3 for <ce> parameter are equivalent to former values 100 and 101. Those
values are managed for compatibility purpose, but they shouldn’t be used in new code
(2 as former 100, and 3 as former 101).
Syntax:
AT+CBST= <speed>, <name>, <ce>
