The command handling (sensors position and command syntax) depends on the module series:
• SARA-R4 / SARA-N4 - The AT command returns the value measured by the temperature sensor close to
the oscillator (XO).

Parameter Type Description
<unit> Number Select the measurement unit for value representation:
• 0: values in tenth of Celsius degrees returned
• 1: values in tenth of Fahrenheit degrees returned
<pmic_temp> Number Fetched value of XO temperature of the selected measurement unit; the allowed
range depends on the measurement unit:
• Celsius degrees: [-40; 140]
• Fahrenheit degrees: [-40; 284]
• 655355: no valid temperature measure is available

14.7.1Description
Enable the UEs power saving mode (PSM) and configures the corresponding parameters. The command
configures the PSM on the UE, as well as:
• the requested extended periodic RAU value in GERAN/UTRAN
• the requested GPRS READY timer value in GERAN/UTRAN
• the requested extended periodic TAU value in E-UTRAN
• the requested Active Time value
See the URCs provided by command +CEREG for the Active Time value and the extended periodic TAU value
that are allocated to the UE by the network in E-UTRAN.
Use the read command to get the assigned values from the network:
• If the power saving mode is enabled (+CPSMS: 1), everything on the device will power down except the
real-time clock (RTC) after the expiry of T3324 (Active Time). It will stay powered down until the expiry of
T3412 (Extended TAU Timer) or if the Power On line is toggled.
• If the power saving mode is disabled (+CPSMS: 0), the device will not enter Power Save Mode (PSM)
SARA-R4
The URCs provided by the +CEREG AT commands for the Active Time value and the extended periodic
TAU value are not supported.
SARA-R4
The read command will return the requested values. See the +UCPSMS AT command to get the values
assigned from the network.
