3.4. Power Saving
Upon system requirement, there are several ways to drive the module to enter low current consumption
status.
3.4.1. Light Sleep
In Light Sleep mode, the serial port does not work, and the module can be woken up through the falling
edge of PSM_EINT.
In this mode, the UART port is inactive and the module can be awakened through the main UART port.
3.4.2. Deep Sleep
The module consumes extremely low current in Deep Sleep mode (typical value: 800 nA). The main
purpose of Deep Sleep is to reduce the power consumption of the module and prolong the power supply
time of the battery.
In Deep Sleep mode, the serial port does not work. The following figure shows the power consumption
diagram of the module in different modes.
