Control ClickBeetle “BlueBeetle” RBG LED via RaspberryPi Zero W

RaspberryPI Zero W contains WLAN and Bluetooth with LE capability. This makes it perfect controlling BLE peripherals via the BLE-stack Bluez like FEEUs ClickBeetle ( Bluez versions in the aptitude repository are pretty old. For this reason it is better to use Bluez from and compile it. First get sure bluez is uninstalled: sudo apt-get … [Read more…]
