Power up the Feather via USB. You'll see the NeoPixel light up red. Open the Bluefruit Connect app and connect to the board. Once a connection is established, you'll see the NeoPixel light up blue.
Navigate to the Control Pad in the Bluefruit Connect app. Use the number buttons to send the UART commands to the RS232 device.
Customization
You can update the code to work with your RS232 device. At the top of the code, the serial baud rate and commands are defined.
# baud rate for your device baud = 38400 # commands for your device commands = ["AVI=1", "AVI=2", "AVI=3", "AVI=4"]
You can add the commands as strings and they'll be encoded in the loop.
