The BarButtons are basically a small Bluetooth keyboard, built for use on a motorcycle. The primary use of the BarButtons is to control navigation apps on your smartphone. To use it you first have to pair it with your phone. Then you possibly have to configure the apps you are going to use to accept keyboard commands. The BarButtons come with different keymaps and have a single status led that shows the current keymap and other information. Lastly, you might want to update the firmware to get new functionality
