16 Data commands
16.1 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.
16.1.1 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:
z 8 data bits, with no parity
z 7 data bits, with even parity
16.1.2 Switch from offline to online mode
See the ATO command description.
16.2 Bearer type selection +CBST
16.2.1 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, whereas 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.
Note 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).
16.2.2 Syntax :
Command syntax: AT+CBST= <speed>, <name>, <ce>
