Bluetooth BLE chips are suitable for intelligent wearable devices. Wearing smart watches, wearing smart glasses on the bridge of the nose, and wearing wireless headphones on the ears... In recent years, the smart wear industry has developed rapidly, and products such as smart watches and headphones are increasingly favored by people. Some experts say that with the further development of technologies such as 5G, AI, and cloud computing, the intelligent wearable device market will face greater development opportunities. According to experts, with the continuous upgrading of wearable devices and the decentralization of new functions, the wearable device market in China continues to develop rapidly, and the shipment volume is increasing year by year. Data shows that the shipment volume of wearable devices in China has increased from 38.76 million units in 2016 to 107 million units in 2020, with a compound growth rate of nearly 30%. The shipment volume of wearable devices in China in the first half of 2020 was 63.43 million units, a year-on-year increase of 43.51%.

Bluetooth is a personal area network technology designed and launched by the Bluetooth Technology Alliance, applied in fields such as healthcare, sports and fitness, beacons, security, and home entertainment. Due to its low power consumption, Bluetooth's low-power technology is often used to significantly reduce power consumption and cost while maintaining the same communication range. Therefore, it is often used on various universal wearable devices and IoT devices, using button batteries for several months to several years, and is compatible with most existing mobile phones, tablets, and computers.

Bluetooth enables wearable devices to achieve low-power connections and basic data transmission without the complexity of other wireless communication standards, helping to develop Bluetooth wearable devices that are small in size, long-lasting in use, and can seamlessly connect smartphones.
