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.
