BLE Smart Home Devices: How Does Bluetooth Technology Work?

Since the COVID-19 outbreak, everyone has been forced to stay indoors and can’t go to the gym anymore. As people still want to stay in shape, exercising at home is becoming more and more popular. But this new fitness culture isn’t limited to home workouts. Professional athletes and fitness enthusiasts alike turn to science and technology to collect data on their performance, analyze it, and receive recommendations for improvement, just as they do in individual in-person coaching sessions.As a result, the global sports analytics market is starting to grow and is expected to exceed $10 billion by 2028, up from $2.2 billion in 2020. The global sports tech industry is expected to reach $17.9 billion by 2026. Furthermore, the number of wearable IoT devices globally is growing rapidly as more and more people are becoming aware of the benefits, security and convenience of technology.In the most basic case, users wear IoT fitness trackers to capture different parameters, such as the user’s pulse, to estimate calories burned, and monitor their training intensity.Professional athletes opt for more sophisticated measurement methods, such as motion tracking, where athletes wear numerous sensors to capture and transmit data on their body posture to build models of their bones. This helps in understanding human body posture and making progress in sports such as javelin throwing and fencing. In addition to postural positioning and movement, sensors can also measure intensity.

Bluetooth IoT and Sports Fitness

The application of Bluetooth IoT in the field of sports and fitness is wearable devices, including devices that monitor blood pressure, EMG temperature, blood sugar, blood pressure and oxygen levels. Wearable devices can collect data on physiological and biochemical parameters, which is critical for patients with chronic diseases or users who need to track specific physical activities.The Internet of Things (IoT) in the field of sports and fitness has the advantages of simplifying the collection of physiological data, monitoring the intensity of human physical activity, and improving sports and fitness programs. Using the Bluetooth technology of the Internet of Things, especially wearable technology, can help users better understand their exercise data, optimize their exercise and fitness plans, and achieve better exercise and fitness.Wearables can also collect vast amounts of data to help users identify correlations between health conditions that need to be dealt with effectively. Heart disease treatment has benefited from the study and monitoring of fitness data with wearable trackers. The system allows users to monitor a patient’s daily intake, calories and daily activity, and can store patient data immediately in medical records and online databases. These devices can help health organizations collaborate remotely to simplify and improve medical processes.The wearables market is expected to reach $30 billion by 2027, and the number of wearables is expected to exceed 1 trillion by 2022. This is an exponential growth rate, which will require proper security measures. Therefore, the sports and fitness industry needs to prepare for these changes and adapt quickly. It is necessary to invest in a safe and reliable system to support the future use of wearable technology.Bluetooth is a personal area network technology designed and marketed by the Bluetooth Special Interest Group for emerging applications in healthcare, sports and fitness, beacons, security, home entertainment, and more. Compared with classic Bluetooth, Bluetooth low energy technology aims to significantly reduce power consumption and cost while maintaining the same communication range. Due to low power consumption, it is often used in various common wearable devices and IoT devices. Button cells can run for months to years, are small in size, low in cost, and compatible with most existing mobile phones, tablets and computers.Bluetooth enables low-power connectivity and basic data transfer in wearable without the complexity of using other wireless standards, enabling the development of Bluetooth wearable devices that are compact in size, have long battery life, and can seamlessly connect to smartphones.

The Bluetooth Low Energy protocol can be perfectly applied to wearable devices for the following reasons:

• The protocol is carefully optimized for ultra-low power consumption.
• Low power consumption helps reduce battery size, thereby reducing product cost, size and weight.
• Since the BLE smart-ready host is used on smartphones, it is easy to implement the protocol.
• Wearable devices exchange small bursts of information over long time intervals.
