According to the 2020 Bluetooth Market Report, the most rapidly evolving area of Bluetooth solutions is location services. Annual shipments of Bluetooth location services applications are expected to increase to 538 million by 2024, compared to an estimated CAGR of 34% between 2019 and 2024. Bluetooth's new directionalization function allows the system to identify the device position by signal strength and orientation at the same time, and its accuracy can be improved to the centimeter level. Find, support for high-precision indoor positioning, enabling developers to optimize Bluetooth location services.
The latest development trend of Bluetooth technology shows that in the operating temperature range of -40 °C to 85 °C, Bluetooth technology can also be used in outdoor industrial equipment and other equipment with poor temperature conditions, combined with the basic functions of bluetooth in the past, making data communication simpler, lower power consumption, and will also meet the huge demand from the industrial equipment market.
Bluetooth industry development
At present, the mainstream indoor positioning technology is Bluetooth, WIFI, RFID, UWB, these several positioning technologies need to deploy a positioning base station, and the positioning distance is relatively close. Hangfei optoelectronics adopts the mainstream three-point positioning Bluetooth technology in the market, and the significant advantage of Bluetooth positioning is that the power consumption is low, and the objective conditions are the same, in terms of the reliability of the positioning network to the system, Bluetooth positioning is more stable. To a large extent, Bluetooth terminals are mostly displayed with Bluetooth cards and Bluetooth bracelets, mainly used in factory positioning, shopping mall positioning, hospital positioning, item anti-loss, shoppingmall positioning, entertainment venue positioning, WeChat shake and other scenarios.
Bluetooth technology
In real life, Bluetooth technology also plays a role in fighting the new crown epidemic and protecting security. While Bluetooth technology alone can't end the virus, it's valuable for developing more effective, lower-cost solutions. Enclosed spaces can be maintained safe, close contact avoidance, and crowds are avoided while minimizing the burden on employees and customers.
Bluetooth technology trends
In today's era, Bluetooth technology has become the standard for smartphones and mobile devices. Bluetooth solutions are also increasingly being used in devices that were not intended to have this technology. The use of Bluetooth technology in different markets and innovative areas continues to increase, gradually becoming one of the best communication technologies for customers. Bluetooth technology is also known for its superior low power consumption and versatility, allowing it to be used around the world. With the development of the Internet of Things, IoT Bluetooth technology can be leveraged in industries that have not yet implemented wireless IoT technology on a large scale.
Lenz Technology launched the ST17H66 Bluetooth BLE5.2 chip, which can realize the Bluetooth positioning function.
ST17H66 Bluetooth BLE5.2 chip
ST17H66 Bluetooth BLE5.2 chip is the latest 16-foot Bluetooth BLE chip from Lenz Technology, with 256KB Flash + (96KB ROM) + 64KB SRAM, the Bluetooth protocol stack is cured, and it no longer occupies Flash space. 64KB of SRAM, partitioned to save more user data while in standby, can set up large-capacity buffers, and supports more complex functions. Ad hoc networking applications that comply with SIG specifications. Includes multi-node control, as well as 2 masters and 4 slaves working simultaneously.
The biggest advantage is the reduced power consumption. The previous generation of Bluetooth receives peak current >13mA; The MCU consumes ~0.5mA/MHz; the average current in low-power mode >40uA. The new Bluetooth receives a peak current of 8.6mA, the power consumption of the MCU
Lenz Technology has independent research and development of radio frequency and Bluetooth low energy BLE5.2 chip and has global intellectual property rights, for the AIoT Internet of Things field and individual consumers, to provide Bluetooth master control fully integrated chip "hardware and software commonality" solution and core devices, supporting a full range of APP software platform custom development. The designed Bluetooth chip solution is applied to smart wearable devices, Bluetooth indoor navigation, smart home, medical health, sports construction, data transmission, remote control, personal peripherals and AIoT Internet of Things and other scenarios.
