HOW TO GET STARTED
1. Connect the FRDM-KW38 board
to a PC using the included micro-USB
cable to the USB OpenSDA connector
of the FRDM-KW38.
2. Your FRDM-KW38 RGB LED should start
cycling through the colors White, Magenta, Blue, Cyan, Green,
Yellow and Red when you connect the board.
3. Using a smartphone supporting
Bluetooth® Low Energy (Bluetooth LE),
install and open the NXP IoT Toolbox
mobile application, available in Google
Play or AppStore. Open the “Beacons”
demo and the FRDM-KW38 Beacon will
be displayed.
4. Explore more out-of-box demos and
