3.4. Operating Modes
The table below briefly summarizes the various operating modes referred in the following chapters.
Table 5: Overview of Operating Modes
Mode
Details
Normal
Operation
Idle
Software is active. The module hasregistered on network, and it is ready
to send and receive data.
Data
Network connection is ongoing. In this mode, the power consumption is
decided by network settingand data transfer rate.
Minimum
Functionality
Mode
AT+CFUN
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
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.
During this mode, the module can still receive paging message, SMSand TCP/UDP data
from the network normally.
PSM*
A UE may adopt the PSM (Power Saving Mode) for reducing its power consumption.
PSM is similar to power-off, but the UE remains registered on the network and there is no
need to re-attach or re-establish PDN connections. When the module is successfully
entered into the PSM, PSM_IND* outputs a low level.
Power Down
Mode
In this mode, the power management unit shuts down the power supply. Software is not
active. The serial interface is not accessible. Operating voltage (connected to VBAT_RF
and VBAT_BB) remains applied.
1. In PSM or sleep mode, it is recommended to use UART interface for module connection. USB
connection is NOT recommended as it will cause increase in power consumption.
2. “*” means under development.
3.5. Power Saving
3.5.1. Sleep Mode
BG96-NA is able to reduce its current consumption to a minimum value during the sleep mode. The
following section describes power saving procedure of BG96-NA module.
