Continuous Glucose Monitoring (CGM) is evolving from an auxiliary tool in diabetes management to a core component of personal health management. In this transformation, the Texas Instruments (TI) CC2340R5 series of low-power Bluetooth chips and RF-star's module solutions are injecting core momentum into the intelligence and accessibility of CGM through their exceptional performance.

• Market & Trends: The Broad Prospects and Intelligent Leap of CGM

Surging Market Capacity: Up to 500 million diabetic patients globally have created massive demand for CGM. The market size is advancing towards tens of billions of US dollars and continues to grow at a high speed. Driving this growth is users' pursuit of more accurate, more comfortable, and easier-to-use products.

AI-Powered Evolution: The value of CGM has transcended "monitoring" and is evolving towards "management and alarm." The introduction of Edge AI is a key step. As TI states, placing intelligence at the device edge enables faster response and greater privacy. This allows CGM to:

• Accurate Prediction: Provide early warnings for high/low glucose events.
• Personalized Insights: Analyze the correlation between diet, exercise, and blood glucose, offering personalized advice.
• Closed-Loop Control: Serve as the core, driving the "Artificial Pancreas" (Automated Insulin Delivery system) to achieve automated glucose management.

• Connectivity Cornerstone: Bluetooth Technology Builds the CGM Wireless Ecosystem

Bluetooth Low Energy (BLE) technology is the invisible bridge connecting CGM sensors to the digital world. Its typical application architecture is as follows:

Highlighting Connection Value

• Real-Time & Convenient: Data seamlessly syncs to phones and watches, allowing users to view trends anytime, eliminating cumbersome manual readings.
• Remote Monitoring: Data is uploaded to the cloud via smartphones, enabling family members to receive alerts remotely, creating a safety net for patients.
• System Integration: Acts as a communication hub, connecting CGM to insulin pumps, forming the cornerstone of automated closed-loop therapy.

Medical devices with similar miniaturization needs as CGM, such as Vital Signs Monitoring (continuous blood pressure monitors, smart temperature patches, pulse oximeters, smart ECG patches/handheld devices, etc.), Drug Management & Therapy (smart insulin pens/injectors, smart inhalers, smart pillboxes, etc.), Remote Patient Monitoring & Chronic Disease Management (wearable physiological parameter monitoring patches, fall detection and alert devices, etc.), and Rehabilitation & Assistive Technologies (smart hearing aids, traditional connected glucose meters, etc.), can all be empowered by selecting the CC2340R5 series products. Let's look at the performance and advantages of this chip series next.

• Core Engine: Features and Advantages of the CC2340R5 Chip

The features of Texas Instruments' CC2340R5 series chips are highly aligned with the stringent requirements of CGM:

• Ultra-Low Power Consumption: Industry-leading low power consumption significantly extends sensor battery life, supporting 7-14 days of long-term wear, or enabling product miniaturization and improved comfort.
• Robust RF Performance: With up to +8 dBm output power and -100 dBm receive sensitivity, it ensures more stable connections and longer range, reducing the risk of data interruption and safeguarding the continuous transmission of life-critical data.
• High Integration: Built-in abundant memory and computing resources (512 kB Flash, 36 kB SRAM) can act as the main controller (core: 40 MHz ARM Cortex-M0+), simplifying peripheral circuits, helping customers reduce costs and shrink size, and supporting potential future OTA upgrades.

• Implementation Bridge: RF-star's Module Solutions

As a long-term partner of TI, RF-star Technology's Bluetooth modules based on the CC2340R5 provide CGM manufacturers with plug-and-play core connectivity capabilities. Below is an introduction to its core modules:

Comprehensive Empowerment Value

• Accelerate Time-to-Market: Some modules are pre-certified (BQB/SRRC/FCC/CE, etc.), allowing customers to bypass lengthy RF development and certification cycles and launch products rapidly.
• Reduce Risk: Provide proven stable hardware and easy-to-use software AT command sets, lowering the development barrier and ensuring consistency in mass production.
• Support Upgrades: The module's firmware foundation supports OTA upgrades, enabling the exploration of more complex edge intelligence algorithms on the device.

• Conclusion

The popularization and intellectualization of CGM deeply rely on the innovation of underlying technologies. The Texas Instruments CC2340R5 chip provides an ideal performance foundation, while RF-star's module solutions build the bridge from chip to product. The combination of the two is helping CGM manufacturers efficiently develop more reliable, intelligent, and user-friendly products, jointly advancing precise health management into a new era.
