3.3. Operating Modes
The following table briefly outlines the operating modes to be mentioned in the following chapters.
Table 5: Overview of Operating Modes
Mode
Details
Normal
Operation
Idle
Software is active. The module has registered on the network, and it is
ready to send and receive data.
Talk/Data
Network connection is ongoing. In this mode, the power consumption is
decided by network setting and data transfer rate.
Minimum
Functionality
Mode
AT+CFUN=0
command can set the module to a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card will be
invalid.
Airplane Mode
AT+CFUN=4
command or W_DISABLE# pin can set the module to airplane mode. In
this case, RF function will be invalid.
Sleep Mode
In this mode, the current consumption of the module will be reduced to the minimal
level. In this mode, the module can still receive paging message, SMS, voice call and
TCP/UDP data from the network normally.
3.4. Power Saving
3.4.1. Sleep Mode
UC200T-GL Mini PCIe is able to reduce its current consumption to a minimum value in sleep mode. There
are three preconditions must be met to make the module enter sleep mode.
Execute
AT+QSCLK=1
; to enable sleep mode.
Ensure the DTR is kept at high level or be kept open.
The host’s USB bus, which is connected with the module’s USB interface, enters suspend state.
3.4.2. Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and all AT commands related to
it will be inaccessible. For more details, please refer to
