Can the user’s heart rate and activity indicators synchronize data is sent to the smartphone applications based on smart watches Bluetooth low energy sensors

Nordic Semiconductor announced in Shenzhen smart wearable device technology development companies are choosing Nordic love of nRF52840 low-power Bluetooth technology (Bluetooth Low Energy (Bluetooth LE)) / 5 advanced multi-protocol Bluetooth system-on-chip (SoC) for smart ID205 watches provide core processing and wireless connectivity. ID205 smart watch weighs only 39 grams, stylish, waterproof function, so users can access and control certain functions of smart phones via Bluetooth wireless connection mobile phone App, such as vibrating alert calls, reject calls and music control function Copyright control Engineering , and can be used as wearable health and heart rate monitor , comprising 14 kinds of movement modes. ID205 smart watch Nordic SoC by using the 64MHz, 32 bit processor power Arm Cortex M4F three built-in sensors include: a 24-hour day, the heart rate monitor and collect user data for analysis of the heart rate sensor personal health; for calculating a activity indicators, such as the number of walking, calories burned and the accelerometer sleep time; and a light sensor to automatically adjust screen brightness in accordance with an external device light changes. After
collect raw sensor data Control Engineering Copyright , love science and technology have to measure the user’s health and activity indicators through independent research and development of algorithms, then the use of low-power Bluetooth connectivity Nordic SoC offers, the data is sent to the user’s Bluetooth 4.0 (or later) smartphone APP “VeryFitPro”, the APP is compatible with iOS and Android. By matching this mobile application, users can view their activity data and trends, as well as update settings and functions of the wearable device wirelessly. ID205 smart watch 210mAh rechargeable lithium polymer battery, according to usage, may provide a full charge run time 10-15 days or about 45 days of standby time, thanks to ultra-low power operating characteristic of the Nordic nRF52840 SoC. nRF52840 using automatic power management system, designed to maximizeExtent reduce the power consumption, as compared with nRF51 series of devices which reduce power consumption as much as 80%. Nordic nRF52840 Nordic multi-protocol SoC is the most advanced ultra-low-power wireless solutions to support complex low-power Bluetooth and other low-power wireless applications, and these applications previously not achieved by a single-chip solution. nRF52840 Bluetooth 5, Thread 1.1 and Zigbee PRO (R21) and a green power source authentication agent specification, the dynamic multi-protocol support for unique features of each protocol concurrent wireless connections. nRF52840 M4F combines multi-protocol processor and 2.4GHz radio (Bluetooth 5, ANT, Thread, Zigbee, IEEE 802.15.4 protocol, and the RF 2.4GHz proprietary software), and having a 1MB Flash memory 256kB RAM. On-chip power amplifier having a new radio architecture -95dBm RX sensitivity (at 1Mbps Bluetooth low energy), 8dBm 103dBm total maximum output power and link budget. Compared with Bluetooth 4.2, Bluetooth supports all of the chip 5, including the range of 4 times or 2 times the original data bandwidth (2Mbps). nRF52840 SoC using Arm CryptoCell-310 encryption accelerator to provide the best in class security, designed to address the inherent security challenges facing things. The SoC device provided with the Nordic S140 along with the protocol stack, which is used to build large data and remote authentication software low-power Bluetooth 5 Bluetooth protocol stack. Nordic software architecture includes clear separation between the RF protocol software technology and love all the application code, make sure that when developing, compiling, testing and validation of application code stack is not destroyed, simplifies the development work. S140 stack provides concurrent central, peripheral, broadcaster and low-power Bluetooth observer role, and support for high throughput and extended remote mode and broadcast both love Ryan Ho, vice president of Technology, said: “We choose to ID205 smart watches the Nordic nRF52840 SoC, since the chip with Bluetooth 5.0 compatible, but it ARM Cortex-M4 processor performance can be achieved faster and more complex calculations, and the realNow Flash and RAM memory allocation. “” In addition, application code and protocol stacks are separated , as well as Nordic Software Development Kit (SDK), are also taken into account when making decisions of our key features, which allows us to focus on development applications without having to spend time on the Bluetooth connection. “” Nordic prestigious in the industry CONTROL ENGINEERING China Copyright , its technology and products to gain market widely recognized. In addition to the chip itself with excellent performance, Nordic community developer-friendly, fast and application support engineer, is also an important decision factor. ”
