3.4. Operating Modes
The following table briefly outlines the operating modes to be mentioned in the following chapters.
Table 7: Overview of Operating Modes
Modes
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
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
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.
Power Down
Mode
In this mode, the power management unit (PMU) shuts down the power supply,
software goes inactive and the serial interfaces are not accessible. However, the
VBAT_RF and VBAT_BB pins are still powered.
3.5. Power Saving
3.5.1. Sleep Mode
EC200T series is able to reduce its current consumption to an ultra-low value in the sleep mode. The
following section describes power saving procedures of EC200T series module.
