Details
The module remains registered on the network and is ready to send
Idle
and receive data. In this mode, the software is active.
The module is connected to the network. Its current consumption
Connected
varies with the network setting and data transfer rate.
The module and network may negotiate over non-access stratum signaling the
use of e-I-DRX for reducing power consumption while being available for mobile
terminated data and/or network originated procedures within a certain delay
dependent on the DRX cycle value.
AT+CFUN=4 or W_DISABLE# pin can set the module to airplane mode where the
RF function is invalid.
AT+CFUN=0 can set the module to minimum functionality without removing the
power supply. In this mode, both RF function and (U)SIM card are invalid.
The module retains the ability to receive paging messages, SMS and TCP/UDP
data 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. The
software is inactive, the serial interfaces are inaccessible, while the operating
voltage of VBAT_BB/RF is still maintained.
PSM is similar to power-off, but the module remains registered on the network
and there is no need to re-attach or re-establish PDN connections. The current
consumption is minimized.
The module can burn firmware with an empty serial flash, or recover from
firmware malfunction. For more details, see Chapter 3.6.
