I am trying to build a wireless electronic drum kit, where my drum triggers transmit the input to a computer via the Sparkfun bluemate and an Arduino Pro. However, I am experiencing significant end-to-end latency to the point where real time live play isn’t feasible. I’m pretty sure most of the latency is from the bluetooth itself and not my code. I am wondering if using the high-level Arduino language (I simply call serial.print to tx over BT) in conjunction with the “plug-and-play” bluemate (which utilizes the RN-41 radio from Roving Networks) is just inherently too laggy, and if it is possible to get the performance I need if I talk to this radio with lower level language (e.g., Atmega assembly language directly to RN-41 chip).
Has anyone had good results for a similar real-time application (desired latency < 20-30 ms end-to-end) using this hardware? Or, could anyone suggest a different platform?
