Bluefruit LE firmware 0.6.6 was just released with a number of new features including HID mouse, HID media controller support — allowing you to set volume, change music tracks, adjust screen brightness and other goodness on compatible devices — and a preliminary set of Eddystone commands (Google’s updated UriBeacon standard for BLE beacons). To update to the latest firmware, simply connect to your Bluefruit LE device using our Bluefruit LE Connect app for Android or iOS and select the appropriate update dialogue. Be sure to get the latest version of the Bluefruit nRF51 library to benefit from the latest features (you can update from the library manager inside the Arduino IDE, 1.6.0 is the version corresponding to the latest firmware release)!
