At present, the entire Bluetooth market is in a golden period. The Internet of Things needs to transfer the collected data from the sensor layer to the core network layer, and ultimately achieve intelligent solutions at the application layer. At present, the core network layer still adopts traditional methods, and the data transmission adopts the core network architecture of traditional fixed network and cellular mobile network. However, the communication technology of the sensing layer is flourishing, with significant breakthroughs in both short distance access and low-power wide area network (LPWAN) camps, with the former mainly including Bluetooth low-power (BLE), Zigbee, WiFi, etc

At present, Bluetooth technology has surpassed all other technologies in the application of IoT devices and has become the preferred technology for IoT. By 2021, 13 billion Bluetooth IoT devices will be put into use. The development of BLE will have a decisive impact on the entire Bluetooth market. According to the latest report from the Bluetooth Technology Alliance (SIA), the shipment volume of BLE single mode devices is expected to more than triple in the next five years. It is expected that by 2025, 96% of Bluetooth devices will include low-power Bluetooth. This is because BLE can fully connect the nodes between the Internet of Things and intelligent sensing devices, which are the core force of the development of the Internet of Things ecosystem. By connecting billions of intelligent sensing devices, the entire Internet of Things can achieve true development. Moreover, the entire Bluetooth technology has always focused on upper level applications with unified standards. Therefore, although various underlying hardware come from different manufacturers, they can be interconnected and form a complete ecological environment, creating a good environment for themselves and the IoT product market.

In the Bluetooth family, BLE surpasses classic Bluetooth in terms of power consumption, speed, and cost. After upgrading to version 5.1, it can also compete with Wi Fi in many aspects. For example, in terms of transmission rate, BLE has reached 2Mbps and can be used for transparent transmission. Although Wi Fi has a high rate, its transmission ability in controlling applications is not strong. In terms of transmission distance, BLE can currently reach a level of 50m indoors, which is even better than Wi Fi at high transmission power. In terms of networking capability, BLE's mesh networking theory can reach 65000, and in actual measurement, it can reach thousands of nodes. Based on such outstanding performance, BLE has achieved comprehensive development in fields such as intelligent industry, smart home, and electronic products. Bluetooth modules equipped with this technology are widely used in fields such as smart home, smart wearable devices, consumer electronics, instruments and meters, smart transportation, smart healthcare, security equipment, automotive equipment, remote control, etc. Tuyang Technology provides a complete set of intelligent audio mass-produced product solutions for enterprise users and individual consumers, accompanied by customized development of a comprehensive APP software platform. With the gradual layout of IoT infrastructure.
