Before continuing make sure your board's lib folder or root filesystem has the adafruit_airlift and
adafruit_ble folders copied over.
Install the Adafruit Bluefruit LE Connect App
The Adafruit Bluefruit LE Connect iOS and Android apps allow you to connect to BLE peripherals that
provide a over-the-air "UART" service. Follow the instructions in the Bluefruit LE Connect
Guide (https://adafru.it/Eg5) to download and install the app on your phone or tablet.
Copy and Adjust the Example Program
Copy the program below to the file code.py on CIRCUITPY on your board.
TAKE NOTE: Adjust the program as needed to suit the AirLift board you have. Comment and
uncomment lines 12-39 below as necessary.

# If you are using CircuitPython 6.0.0 or earlier,
# on PyPortal and PyPortal Titano only, use the pin settings
# below. Comment out the DEFAULT line above and uncomment
