The Telit Modules provide a function that reduces the power consumption during the
period when they are in IDLE state (waiting for a call), allowing for longer activity with a
given battery capacity.
The power saving function can be configured in several modes according to the user’s
needs.
According to the answer of the AT+CFUN=? Command, you can know the Power Saving
Modes supported by the Telit Module, please refer to the AT Commands Reference Guide
for more details. In power saving mode with CFUN=5, UART AT interface disabled. URC
is not displayed and is stored in the buffer on UART AT interface. It flushed to DTE when
the modem device exit power saving mode by <DTR=ON>.
AT#PSMRI=<duration time> must be configured as non-zero value. It enables RI with the
specified time if URC event happened during power saving mode with CFUN=5.
