In the current era of the Internet of Things, Bluetooth, as a short distance communication technology, is playing an increasingly important role. Short range low-power Bluetooth has been widely used in scenarios such as smart home devices and wearable devices. As a wearable device, smart bracelets are the mainstream product in the wearable market. High cost-effectiveness, small size, and low power consumption are the three key elements in designing solutions. The BLE Bluetooth low-power bracelet obtains relevant vital signs of humans through sensors and transmits them to the mobile app through Bluetooth, thereby achieving data storage and analysis functions. Tuyang has launched a Bluetooth intelligent bracelet solution, using the Jerry BLE Bluetooth chip AC6323A Bluetooth intelligent chip. The rich intelligent compatible design scheme has biosensing functions, and the simulated front-end solution can achieve high-precision optical heart rate to track user data and provide users with comprehensive understanding of their health status through APP analysis. And it integrates customized functions such as voice commands, time notification, and music playback. The Bluetooth smart bracelet monitors the user's exercise volume, calories, and sleep time through sensors, and transmits data to the mobile app through Bluetooth, which provides corresponding exercise reminders and health guidance. The bracelet can also be equipped with an alarm clock function, embedded Bluetooth anti loss function, automatic alarm reminder when exceeding the range, and can also serve as a mobile phone remote control for phone photo control.
