I appreciate the quick feedback! I am implementing your SimpleBluetoothIO class and I am currently toggling an LED and a servo from my Arduino 101. My problem is that the LED and the servo are switching/turning at the same time. Is there a way to separate that signal? For example, I want to only turn the servo from a UISwitch and only turn the LED on/off from a UIButton. Haven’t had very much luck googling this. Any help would be greatly appreciated!
