AT command
AT+KSLEEP
enables the sleep mode configuration below.
AT+KSLEEP=0

The modem is active when DTR signal is active (low electrical level).

When DTR is deactivated (high electrical level), the modem enters sleep mode after a while.

On DTR activation (low electrical level), the modem wakes up.
AT+KSLEEP=1

The modem determines when it enters sleep mode (when no more tasks are running).


AT+KSLEEP=2

The modem never enters sleep mode.
In sleep mode, the modem reduces its power consumption and remains waiting for the wake-up
signals either from the network (i.e. read paging block depending on the DRX value of the network) or
the operating system (i.e. timers wake up timers activated) or the host controller (i.e. character on
serial link or DTR signal).
