Bluetooth Low Power Consumption Mode

After Bluetooth enter low power consumption mode, the BLE 4.1 consumes lower than 10uA,

and it can still broadcast and keep data interaction. With command AT+LOWPOWER=ON,

BLE4.1 device will enable low power consumption mode after you reboot the device. BLE4.1

device will enter this mode in 10s. You can also use AT+BOOT to make a software reboot.

Here is something you should notice: The MCU should WAKEUP the BLE Chip first, or it will

be messy code.

In the low power consumption mode, if there is no extra operation, Bluetooth will enter this

mode after 10s. You can awake Bluetooth by interruption pins; awake ATmega328P by

Bluetooth:



BLE4.1 wakes up the Arduino controller (ATmega328P) with P4_2 (D2_Arduino): high voltage

wakeup



Arduino controller (ATmega328P) wakes up BLE4.1 by WAKEUP (D3_Arduino): low voltage

wakeup
