AAC Keys is a keyboard and mouse emulation program for Microsoft Windows-based and Macintosh computers. AAC Keys receives commands through your computer’s serial port and translates them into keystrokes and mouse movements, giving you full control of your computer from another device such as an AAC system. (If your computer has only USB ports, an inexpensive adapter is available.)
Sending Keys/Mouse Via Serial
For advanced users, you may want to hook up your Bluefruit to a microcontroller and send characters or strings via Bluetooth.
You can do this with the UART port on the EZ-Key. The UART pins are labeled RX (data going into the module) and TX (debug data coming out of the module). You can get away with just connecting to RX. The RX pin is 5V compliant, you can send it 3V or 5V TTL logic levels. Use 9600 baud serial, all microcontrollers will support this.
You can also send raw HID Keyboard reports for complex key-stroke combinations and controls.
In version v1.1 (Oct 22, 2013 or later) HID Mouse reports are also supported, you can send mouse movement and clicks via the UART and microcontroller
In version v1.2 (Nov 2013 or later) HID consumer report keys are supported, there are a few supported 'multimedia keys' - see below for a list and how to send via the UART
Don't forget to also tie a ground pin from your microcontroller to the EZ-Key for the logic ground reference!
