This is a Bluetooth Low Energy (BLE) shield for the Adafruit Pro Trinket. As a simple UART pass-through, it has been designed to be as small as possible and make it as easy as possible to use BLE in your Pro Trinket based projects. The BLE Shield is built around the easy to use BLE113 module from Bluegiga, which has its own scripting language that can be used to create a custom BLE implementation. The most important feature of the BLE Shield is that no prior knowledge BLE is needed, the device is configured to be a simple UART pass-through.
