Smart locks and smart sensors have become more and more trendy. Developers can spend a huge amount of time creating and connecting these popular Internet of Things (IoT) products to the cloud via gateways using wireless technologies such as Bluetooth® low energy(LE). Choosing an easy-to-use cloud service that offers powerful functions, steadiness and multiple cloud-security features can also be a challenge, so RF-star and TI worked with Alibaba to provide support for the Ali Cloud Link IoT platform on RF-star Bluetooth low energy CC2640R2F wireless module. RF-star provides a sample application for the CC2640R2F module software development kit (SDK) to support Ali Cloud Link. Through this sample application, you can receive the specific Alibaba profile, which contains a range of security features, over-the-air (OTA) support and good performance for compatibility with iOS and Android platforms. For example, you can use the secure hash algorithm (SHA) 256 security feature and the CC2640R2F wireless module’s true random number generator (TRNG) to generate keys for Advanced Encryption Standard (AES) encryption, which is included in the CC2640R2F device’s hardware encryption engine. This ensures that every communication session gets a different key to improve the security performance for data transmission. With a few simple application programming interfaces (APIs), you can build up a secure Bluetooth low energy product. The Alibaba OTA protocol is fully supported in this sample application. Compatibility with different Android mobile phones has been optimized, especially for China-brand Android phones. Figure 1 shows the architecture of a sample application with theTI CC2640R2F SDK. Figure 1: SDK software architecture for the CC2640R2F wireless module The 2.4GHz  CC2640R2F wireless module supports Bluetooth 4.2 and Bluetooth 5 ultra-low-power applications for IoT applications. The device has extremely low active radio frequency (RF), MCU power and low-power-consumption modes, thus enabling longer battery life. It includes a 32-bit Arm® Cortex®-M3 core as well as many peripheral functions in which there is a unique ultra-low-power sensor controller. The sensor controller is suited for connecting external sensors, and automatically collecting analog and digital data when the rest of the system is in sleep mode. You do not have to worry about issues like protocol interaction and driver development. The CC2640R2F SDK includes: Application code that is 100% portable across the SimpleLink MCU platform from Bluetooth low energy to Sub-1 GHz and more. RFSTAR drivers that provide a standard and unified API interface for all peripheral interfaces of the ti SimpleLink MCU platform, enabling you to write code independent of the targeted device. The integrated TI real-time operating system (TI-RTOS). Other RTOSs like Free RTOS’s adapter interface, which is API-compatible to the Portable Operating System Interface for Unix (POSIX).

Project Name：MIP Robot Toy                     Project Date: 2014 Project Partner: Wow Wee MIP is an interacted toy robot from WowWee. RF-star supported WowWee realized BLE function of MIP which enable the toy connected with the mobile phone. Users can use the APP to achieve more than 8 modes. The robot balance itself on two wheels. This is the first BLE toy in the world, and the fantastic design made WowWee win the one of the 10 best designs in CES 2014

The initial technology maturity curve for iot development is only based on an increase in the number of deployed and potential sensors. Today, we can look to the future and explore some important success factors. Future trends in the Internet of things, including IoT applications, will bring economic benefits to end users. There is also a trend towards longer battery life, lasting for years. In any wireless iot monitoring system, data transmission consumes power. Therefore, the perception and processing take place at the edge nodes through intelligent partitioning, and the amount of data is reduced (in a more sporadic or shorter period) through local decisions, thus bringing significant added value to the iot system. Finally, the key element of the future is the ability to operate safely and reliably. Therefore, for successful iot systems, the focus of iot design will shift to key performance indicators such as trusted sensors and system uptime. Analysts estimate that low - cost development systems are currently in the Peak of expectation inflation. In the next two to five years, differentiated or specialized high - precision sensors and analog signal chains will become the mainstream and truly push the Internet of things market into the future. Importance of Good Data A key process in iot systems is the conversion of analog signals into digital signals. Simply put, the better the transformation,the more useful the data. Silicon technology innovates to transform and interpret the world around it, bridging the real and digital worlds through detection, measurement, interpretation, and connectivity. The most effective iot deployment is the ability to use this data to determine change. And best change is the biggest value for end customer, such as higher efficiency and higher security, such as in factories, machine learning is not only able to identify when may need to machines for predictive maintenance in the future, but also can identify the details and reach a higher level of recognition, to determine what action to take (for example, to identify specific ball bearing in motor wear). Therefore, the first stage of any iot system is to detect, measure, and then convert real-time signals into analytical data. How well this stage is completed will lay the foundation for future success. If the wrong information data is entered, the results obtained from any iot analysis cloud platform will also be wrong. Therefore, the most successful iot systems have to have measurement and reporting levels that other systems cannot. This needs to improve measurement and reporting makes good hardware essential. A recent Gartner report said the same. Report that they are low cost iot development look fast into the bubble period of disillusionment (trough of disillusionment. This may be due to the plethora of low-cost development platforms available. But I think it's more likely that we're focusing on more challenging iot applications that have more real economic valu...

Project Name: Vehicle-mounted Bluetooth Remote Driving                     Project Date: 2019 Project Amount: 1KK/Year Bluetooth remote driving realized remotely controlling the vehicle's low-speed driving by connecting the vehicle's Bluetooth at a short distance, which can help the user to complete the operation of parking and leaving the garage with a mobile phone outside the vehicle. The Bluetooth remote control is not only the easy operation, but very functional, the real-time safety reminder also fully guarantees the personal and vehicle safety of the owner during the Bluetooth remote control driving process. When Bluetooth remote control driving is working, facing complicated road conditions or improper operation by the owner, the system will promptly pop up an alarm prompt, for example, break down, abnormal operation, the terrible road conditions for remote control driving; manual operations such as gear shifting, operating the steering wheel, and opening the door. In these scenarios, the mobile phone application interface will pop up an alarm prompt, and the owner needs to end the remote control driving in time. If you want to continue, you need to click Continue after ensuring that the vehicle environment, vehicle status, and application equipment are normal. The emergence of the Bluetooth remote control driving function not only saves the "parking difficulties" of new and old drivers, but also embodies the true concept of starting from improving the user's driving experience and creating smart travel for users through technological innovation. RF-star BLE solution support the automobile factories to achieve the functions and make the automobile more and more intelligent.
