Description
Set command is used to configure the availability of the radio accesses inherently supported by the MT. E.g. in a GSM-only environment, other radio access technologies could be disabled to reduce power-consumption. Settings are persistent over a power-cycle. It is not supported to set all parameters to indicate "Radio access is disabled", this will cause the MT to return ERROR. +CSRA only configures the requested parameters; no change in the transmit and receive RF circuits takes place by using +CSRA. The actual execution of the configuration is obtained by using +CFUN=128.
Read command returns two lines of information text with two distinct prefixes:
– a line prefixed with +CSRAC: displaying the currently configured +CSRA settings. These values are not activated until +CFUN=128 is executed, and this line does therefore not necessarily reflect the RATs currently activated on the radio interface; and
– a line prefixed with +CSRAA: displaying the RATs currently activ on the radio interface.
Read command returns the current settings in the MT.
Refer clause 9.2 for possible <err> values.
Test command returns values supported by the MT as compound values. The returned values do not reflect network capabilities.
