Bluetooth technology | it is reported that apple, meta and other manufacturers will promote new wearable devices, and Bluetooth will help the development of intelligent wearable devices

Smart watch leader apple and the largest VR Device supplier Meta New wearable devices will be released simultaneously in the second half of the year , samsung 、 Brand factories such as Xiaomi will also release new products in succession , In the second half of the year, the wearable equipment market will be an important new battlefield beyond smartphones .

According to the economic daily report of Taiwan, China , Insiders believe that , The overall global wearable device market continues to grow , Major brand factories will not give up easily , Expectations include apple 、 samsung 、 millet 、 Huawei , even to the extent that Meta Will continue to launch new products . Its main purpose is not to sell the hardware itself , But to enhance brand value , And sell more peripheral services .

According to the Research Institute IDC According to the report ,2021 The annual shipments of wearable devices totaled 5.3 One hundred million units , Year-on-year growth 20%. Products shipped with bracelets 、 Mainly watches , Among them, apple is far ahead of other competitors in the field of smart watches ,Apple Watch Last year 4 The quarterly market share reached 35%, Xiaomi 8.6% Rank second , samsung 7.9% Curie III , Huawei's market share is about 6.7%.

VR In terms of devices ,IDC Statistics , Last year, the world AR／VR Shipment volume of headset 1,123 Ten thousand units 、 Year-on-year growth 92.1%. among ,VR For the first time, the shipment of equipment exceeded 10 million 、 reach 1095 Ten thousand units , Estimate this year VR The equipment shipment will reach 1573 Ten thousand units , Year-on-year growth 43.6%. among ,VR Leading equipment manufacturers Meta Of Oculus The market share is as high as 80% , There is a big gap with other competitors .

As a wireless connection for the interconnection of all things , Bluetooth low power （Bluetooth Low Energy, Or called Bluetooth LE、BLE） It is a personal local area network technology designed and sold by Bluetooth technology alliance , Designed for health care 、 Exercise and keep fit 、 beacon （Beacon）、 Security 、 Emerging applications in the field of home entertainment . Compared with classic Bluetooth , Bluetooth low power technology aims to significantly reduce power consumption and cost while maintaining the same communication range , Due to low power consumption , Therefore, it is often used in various common wearable devices and Internet of things devices , It can be run for months to years with a button battery , Small size 、 Low cost , And with most existing mobile phones 、 Tablet and PC compatible .

Lenz technology launches the latest Bluetooth BLE5.2 chip ST17H65

ST17H65 bluetooth BLE5.2 Chip parameters

ST17H65 bluetooth BLE5.2 The chip is the latest Bluetooth Technology launched by Lenz technology BLE chip , have 512KB Flash +（96KB ROM）+64KB SRAM, Bluetooth protocol stack , No longer occupy Flash Space .64KB Of SRAM, Partition use , More user data can be saved in standby , You can set a large buffer , Support more complex functions . accord with SIG canonical Mesh Ad hoc network application . Including multi node control , And the simultaneous work of one master and multiple slaves .

ST17H65 Yes 23 x GPIO,6 x PWM,-103dBm @BLE 125Kbps,[email protected] 1Mbps. Single ended antenna output , There can be no matching circuit . Support antenna matrix switching , Plug in support LNA Signal amplification .

The biggest advantage is lower power consumption . The previous generation product Bluetooth received peak current >13mA; MCU Power consumption of _{0.5mA/MHz; Average current in low power mode >40uA. The Bluetooth of the new product receives peak current 4.7mA,MCU Power consumption of <60uA/MHz. In low power mode, the average current can be reduced to 20uA}30uA.BLE5 More flexible broadcast packets , Up to 200Byte data ,BLE4 Only 32Byte. Faster transmission rate ,BLE5 You can achieve 20_{30KB/s;BLE4 Generally in 4}5KB/s.

Lenz technology has independently developed wireless RF and low-power Bluetooth BLE5.2 Chip and has global intellectual property rights , in the light of AIoT Internet of things and individual consumers , Provide Bluetooth master fully integrated chip 「 Commonality of software and hardware 」 Solutions and core devices , Supporting all-round APP Software platform customization development . The Bluetooth chip scheme is applied to intelligent wearable devices 、 Bluetooth indoor navigation 、 Smart home 、 Health care 、 Sports build body 、 The data transfer 、 Remote control 、 Personal peripherals and AIoT Internet of things and so on .
