4. Operation modes
4.1 Low Power Mode
Low-power mode: The module enters the low-power mode at once by AT command “AT+SLEEP”, or enter the
low-power mode after disconnecting the “AT+DISCSLEEP=1”setting, the serial port output “STA
：
sleep”when the
command enters the low-power mode at once, if the broadcast function module is not turned off, the broadcast gap as the
wake-up time will broadcast. See
6.37 Get to sleep mode at once
Description
：
1. If broadcasting is turned on in low power mode, the host can scan the broadcast and establish a connection with the
module, and the module wakes up at once after the connection is established.
2. The module enter low-power mode to support serial data wake-up (the first frame data will be lost as wake-up
source data).
