The bluetooth option doesn't actually connect to the camera -- rather, it connects the Timelapse+ device to other Timelapse+ devices, future accessories, and, once apps are made, Bluetooth 4.0 enabled smartphones. So which camera you have doesn't actually matter.
At present, it only is ready for communication between Timelapse+ devices, but keeps the door open for additional options in the future.
Also, since the firmware will be open-source, bluetooth accessories don't even have to come from me. If you are a programmer and have an idea, this can be a great platform to get started with!
