Exploring the Potential of Bluetooth Low Energy for Wireless Sensing and On-Board Computation in Remote Health Monitoring

In recent years, wearable technology has seen a significant increase in popularity, particularly for its ability to track vital health parameters, which has proven invaluable in remote patient monitoring applications. In this paper, an electronic device has been developed with a Bluetooth 5.1 Low Energy (BLE) radio that is capable of detecting, collecting, aggregating and transmitting the Root Sum of Squares Method (RSS) of the acceleration data at regular intervals of 60 seconds to any standard BLE device. This wireless multiprotocol and multiband microcontroller operates on sub-1 GHz and 2.4 GHz frequencies, supporting Bluetooth® 5.1 low energy protocol and other wireless communication protocols through a Dynamic MultiProtocol Manager (DMM) driver. The BMI160 has been designed and specifically programmed to perform acceleration processing on the three measured axes onboard, thereby reducing the amount of data to be transmitted, as well as the communication time. This device can be integrated with other physiological parameter monitoring systems of an individual/patient, making it possible to use these systems for a variety of applications, including healthcare and wellness.
