User Manual

general purpose serial data and is connected to the Serial Monitor. This is the port you should normally select in the

Arduino IDE.

The second port that is enumerated is for basic debugging and for future expansion, and enumerates a currently

unused AT Parser that only supports a very basic set of commands (for example 'ATI' will return some basic information

about the module).

With the right serial port selected (normally the numerically lowest number is the Serial Monitor COM port, though it´s

random and may change from one system to the next), you can open the Serial Monitor and you can send and receive

serial data like you would with any other Arduino development board.

On Windows, you can verify which COM port corresponds to which function by opening the Device Manager and

examining the list of serial ports. COM35 below is the Serial Monitor port (WICED Feather Serial) and COM36 is the AT

parser port (WICED Feather ATParser).

If you are not seeing a USB CDC port and are using a new WICED board, please see this FAQ:
