I wanted to use Bluetooth 4.0 Low Energy with the project, but given the time constraints I will not be able to figure out why my BLE module is not working. I recently purchased a HM-10 Module from Amazon and was going to direct wire (without an adapter board) to the Trinket Pro 3.3V. This module however is not responding when I connect it to a console through a 3.3V FTDI adapter. It is scanable on my Android Phone, but when I attempt to actually serially communicate with it, I get various messages through Android saying connection failed etc.. I am however able to pair the device (code 000000). So for the time being, I will stick with the RN42. Transitioning to the HM-10 may be a future upgrade.
