I believe the following document will be of help for you: https://communities.intel.com/docs/DOC-102152. It explains how to make an automatic connection to a Bluetooth device with a combination of a shell script and a system service.
I'd also suggest you to read Edison's Bluetooth guide: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005743.html it contains a lot of information useful about Edison's Bluetooth stack.
I hope this information provides you a good starting point. I, personally, have never used a Motoduino, so I'd suggest you to post your question in http://www.motoduino.com/forum/motoduino-forum/ in order to get a more accurate response in regard to the Motoduino side.
