Configuration variable reference

The configuration variable space is split into two areas: production data (PDATA) and

configuration data. The production data space contains factory-set variables that can be

modified in RAM (AT+S.SCFG) but cannot be saved to non-volatile storage. The

configuration data space contains variables that can be written in RAM (AT+S.SCFG) and

written to non-volatile storage (AT&W). Additionally, the non-volatile values can be restored

to their factory state using the AT&F command.

Variables have the following types:

The following table lists the production data variables:

The following table lists the configuration data variables:
