B.1î™–î™–î™–î™–Parameters stored in profiles
The parameter settings of some commands can be stored in the profiles available in the memory module.
SARA-R4 / SARA-N4
To partially display these profiles, see the AT&V command description. Not all the parameter setting are
displayed through AT&V command.
Some AT commands have a unique configuration for all the AT interfaces while for other AT commands it
is possible to set a different configuration for each AT interface: the "AT interface configuration sharing"
column in the next table provides this information.
Some AT command interfaces have a dynamic activation, which means they are not statically activated
at boot time (MUX AT channel is activated when the MUX protocol is established, USB AT channel is
activated if/when the USB cable is plugged-in, deactivated when it is removed). Since the activation
reloads the AT command profile from NVM for the activated interface, the shared "AT interface
configurations" could be overwritten. It is suggested to reconfigure them at the requested value if an AT
command interface is dynamically activated.
The following table lists the AT commands which setting can be stored in the profiles with their parameters
as well as the factory-programmed values.
