Bluetooth Low Power Node Latency Optimization

Abstract:

A system and method for optimizing battery life in Bluetooth low power nodes without appreciably affecting latency is disclosed. The low power node may vary its PollTimeout value based on certain criteria, including time of day, ambient conditions or input from other devices. In this way, power consumption is minimized during those times when latency is not anticipated to be problematic, while latency is reduced during other times. In another embodiment, the low power node may save preconstructed messages before going into a low power or sleep mode to minimize the time required to transmit those messages.
