We present a strategy for the improvement of wireless sensor data transmission latency, implemented in two current projects involving gesture/control sound interaction. Our platform was designed to be capable of accepting accessories using a digital bus. The receiver features a IEEE 802.15.4 microcontroller associated to a TCP/IP stack integrated circuit that transmits the received wireless data to a host computer using the Open Sound Control protocol. This paper details how we improved the latency and sample rate of the said technology while keeping the device small and scalable.
