This study evaluates Bluetooth Low Energy (BLE) connectivity in modern continuous glucose monitoring systems (CGMs) for diabetes management. With a focus on FreeStyle Libre 3 and Dexcom G7, the research examines reliability during daytime and nighttime wear by analyzing data gaps in BLE transmission between the sensor and receiver. A sample of 12 participants provides insights into prevalence, duration, and potential implications of these gaps. Results show that L3 achieved an average BLE transmission rate of 93.5% compared to G7's 69.3%, with G7 exhibiting greater variation. Furthermore, G7 experienced significantly more frequent and longer data gaps, highlighting potential limitations in signal reliability. These findings suggest the importance of consistent and reliable data transmission for informed medical decisions and alarm systems. The study underscores the need for patient awareness and future studies to assess the impact of BLE connectivity on patient safety, particularly in the context of integrating CGMs with insulin pumps.
