Evaluating Bluetooth Low Energy Connection Reliability for Mobile Health Applications

Mobile health applications integrated with wearable devices enable continuous monitoring for chronic disease management, but the reliability of wireless connectivity between mobile applications and sensors remains a concern for healthcare applications. This paper presents an analysis of Bluetooth Low Energy connection reliability between the TEMPO mobile application and Movesense wearable devices in real-world hemophilia management scenarios. We conducted a 48-hour continuous monitoring experiment simulating typical patient usage patterns, where users operate the system without active connection management. The experimental setup involved a Movesense HR paired with the TEMPO application running on an Android smartphone collecting IMU data for Human Activity Recognition applications. Our analysis demonstrates that BLE connections achieve a 90% automatic reconnection success rate, with the system effectively handling routine connectivity interruptions without requiring user intervention. The system demonstrated resilience during extended disconnection periods and successfully recovered automatically. These findings support the feasibility of BLE-based wearable systems for reliable healthcare monitoring in chronic disease management.
