Wearable wireless physiological monitoring devices have emerged as powerful tools in healthcare, facilitating continuous monitoring of vital signs and physiological parameters in real-time. Many of these applications require small profile, and low-power battery operated devices. Bluetooth Low Energy (BLE) is a commonly selected wireless communication protocol as it provides fast data transfer, low cost, and low power. Physiological monitoring applications do not have as strict real-time latency requirements as control applications. For control use-cases, such as prosthesis control, real-time latency has a direct impact on user experience. In this work we explored various BLE parameter configurations in a multi-channel sensor node system to determine their relationship to power consumption, the number of supported peripheral nodes, and latency. Data collected during these experiments indicates that using longer connection intervals leads to a decrease in power consumption and that shorter event lengths allows for support of more peripheral sensor nodes for a given connection interval. It was observed that the typical latency between the application of an input signal at a peripheral node and its detection on the central node is approximately one connection interval. Future work should continue to investigate techniques to optimize power consumption, extend the number of supported peripheral nodes, and minimize latency through the system specifically for control applications.
