2.4. Energy-saving Mode
2.4.1. Low Power Mode
When the host and the module are connected through the serial port, the module can enter
the low power consumption mode through the following steps；
 Use AT+PWRM command to enable low power consumption function. For more
information about AT commands, Please refer to "DX-BT24-M&BT24-T Bluetooth
Module_Serial UART_Application Guide".
 In low power consumption mode, the module can be found and connected.
 Send a 200ms low-level pulse to the 12-pin KEY of the module to wake up the module to
normal working mode.
 To enter low power mode again：
When connected: disconnected, the module automatically enters low power
consumption mode；
When it is not connected after waking up: You need to send the AT+PWRM command
again to enter the low power consumption mode or reset, power off and restart to enter.
 For hardware, please refer to 2.5.5 wake-up circuit below.
