Research on the characteristics of Bluetooth low-power positioning chip platform

With the development of the Internet of things technology updates, now low power consumption bluetooth (BLE) technology has a small size, low power consumption and high compatibility characteristics, is applied to product tracking and positioning, and continuous innovation [1]. this paper with apple Find My and Google Find, for example, to discuss the BLE low power technology on the application of application status, technical principle and future development trend. This paper first introduces the principle and characteristics of BLE technology, and analyzes the positioning advantages in the product, and then introduces the working principle of findmy and Google find, including key technologies such as broadcast discovery and location estimation, as well as the power consumption comparison of positioning embedded by other platforms. This paper also introduces the challenges of BLE positioning technology, such as accuracy improvement, signal interference, etc. And look forward to the future development direction and application. The research shows that the BLE positioning field has great application prospects, and the product examples of Findmy and Google find positioning application provide a reference for the popularization of BLE technology. In the future, with the continuous innovation of technology, Bluetooth low-power devices will be continuously developed and applied, and play an important role in their field.
