the power supply. In this mode, both RF function and (U)SIM card are invalid.
Mode
The module remains the ability to receive paging message, SMS and TCP/UDP data
Sleep Mode* from the network normally. In this mode, the current consumption is reduced to a low
level.
The module's power supply is shut down by its power management unit. In this mode,

consumption is reduced to a minimized level.
NOTE
During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB
interface will increase power consumption.
BG772A-GL_Hardware_Design
The module is connected to network. Its current consumption varies
with the network setting and data transfer rate.
The module remains registered on network, and is ready to send and
receive data. In this mode, the software is active.
