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 +WMUX command to enable Commands / Data multiplexing.
Note: currently the +WMUX command is not supported yet.
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 an AT command can be sent.
Note: the “+++” sequence only works with the +ICF command using 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.
