3.3 Introduction to Low Power Mode
3.3.1 Low Power Mode Setting
Turn on or turn off the low power consumption function through the command
"AT+LPM{=Param}".
3.3.2 Low power operation strategy
There are two ways to wake up after entering low power consumption mode:
1.
Send the first packet of data by UART to wake up the mode. The UART will work after
being awakened. Module will close the UART and enter into low power mode if no
UART or APP data received within 10s
2.
Wake up by sending data via app. In low power mode, receiving app data will wake up
UART and output data. Module will close the UART and enter into low power mode if
no UART or APP data received within 10s
