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.
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
Switch from offline to online mode
See the ATO command description.
16.2 Bearer type selection +CBST
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. and ) are meaningful, whereas for an incoming call, only the
parameter is used.
Note 1) For incoming calls, if 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 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).
