OK, it is with a heavy heart that I am forced to switch to ESP8266 (as little as $3, and highly supported by the Arduino community). Sucks, because they use WiFi instead of BlueTooth, so they require a lot more power. I'll wire up a solar cell to keep them alive in my back yard. Extremely versatile little suckers, and they just plain work!
...unless someone has working Swift iOS code for Bean+ on GitHub? anyone???
