Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
Chapter 18 – Sleep Commands
This specific command allows the 32kHz sleep mode to be enabled or disabled. When sleep
mode is entered, the product uses a 32kHz internal clock during inactivity stages.
Command syntax: AT+W32K=<mode>
<mode>
<DTR Used>
The modem will not go to sleep if any of the following conditions are true:
The modem will wake up from sleep when any of the following conditions are true.

DTR cannot be used to wake up the modem
DTR can be used to wake up the modem. DTR high wakes up the modem. DTR low puts
The modem is not registered to the network. If it has stopped searching for a network due
to a UOOS timeout, the modem will go to sleep.
The modem is in the middle of an NV Backup.
DTR is asserted, and it has been enabled as a sleep control (AT+W32K=1,1).
QXDM is running and is connected to the modem.
The modem is in a call state other than idle.
Deep Sleep mode is disabled; i.e., AT+W32K=1 has not been issued.
USB is connected.
Note that if QXDM was running before USB is disconnected, the modem will not go to
sleep. QXDM must be closed before disconnecting USB.
The modem can take up to a minute to enter sleep after the +W32K command is issued.
This can occur when it is in the middle of GPS processing such as GPS demodulation.
Plugging in a USB cable will cause the modem to exit deep sleep.
An incoming call can wakeup the modem from deep sleep. All peripherals (i.e., UARTs,
USB, GPS, etc.) are available while the call is up. Once the call hangs up, the modem will
go back to deep sleep and all peripherals will shutdown.
The UART is connected and the DTR pin is asserted (if AT+W32K=1,1 was issued).
In deep sleep, unsolicited messages are not buffered and will be discarded. If real-time
notifications of events are needed, the Ring Indicator can be used. After the modem
wakes up, new unsolicited messages will be received.
