In the paper,a Bluetooth positioning system based on Angle of Arrival (AOA) method is designed,and build a low-power Bluetooth positioning system based on CC2652R1 Bluetooth development board and STM32 microcontroller.The field test results show that this system can obtain sub-meter accuracy positioning information in indoor complex environment with accuracy up to 20 cm,which is suitable for scenarios such as electric power smart operation and maintenance,smart factory,shopping mall guidance,and warehouse logistics.
