Punch Through Designs makes a cool little LightBlue Bean that I've been having fun with. I've created a custom display for it that uses the i2c pins. Pin0 is the Enable pin for the display. My example code has the Enable pin high all the time but when it is low the power is removed from the display saving drain on the battery.
Sparkfun released a library that works great to quickly get you going but it does not set the Enable pin high. I've slightly modified one of the examples you get you going. Grab my modified example code here.
Problems and issues: - the IOS app right now is very limited in what it can do. You cannot get the display working without a mac that has bluetooth 4.0. My macbook pro is an older 2010 version with bluetooth 3.0 so I'm using a usb bluetooth 4.0 dongle. - a solid connection to the Bean is needed for it to work. The video shows me pushing it into the Bean which is not a solid connection. For the video I had to try a few times before it would work. This was done to show which side it goes onto and what the overall height would be once if you solder it into place. Soldering is recommended but is difficult to remove.
