One of my main goals for the Keyglove is to allow it to be used on as many devices and operating systems as possible with no complicated driver installation or configuration every time you set it up. Using a USB connection and Human Interface Device (HID) profiles, along with the Bluegiga WT12 Bluetooth module that also supports HID profiles, the Keyglove can appear to the host devices as a standard keyboard, mouse, or joystick, none of which require drivers. This allows for basic usage with almost no work.
But what about special types of usage? What about reconfiguring the Keyglove’s behavior, even if most of the time you do just want to use it as a keyboard and mouse? What about extending the capabilities beyond what I imagined, or implementing your own special driver for your particular hardware or software application? Obviously a HID-only approach is too limited. So, we turn to basic serial communication, which is one of the easiest methods to communicate with a hardware device in a way that pretty much anyone can work with, regardless of the platform. It works the same over Bluetooth as it does over a USB virtual serial port (which is built into the main Keyglove processor), and it’s also easy to adapt to a direct connection to another microcontroller, should anyone want to do that.
