Debugging your connection

If your device is not listed in the Device Management Portal, you can use a serial monitor tool, such as CoolTerm, to see debugging messages from the board. Follow these steps:

  1. If you do not already have a terminal application, download and install one. For example, you can download CoolTerm.

  2. Open CoolTerm.

  3. Click Connection > Options. The Serial Port Options window opens.

  4. Enter your connection parameters:

    1. Select the correct serial port:
      • On Mac and Linux, look for usbmodem<ID>.
      • On Windows, look for COM<port>.
    2. Baudrate: 115200.
  5. Click OK.

  6. Click Connect.

  7. Press any button on your board, and you will see connection debug messages in the CoolTerm window.

Tip: For more verbose debug information, set mbed-trace.enable in the mbed_app.json file to 1. For more information, see the error handling and debugging section.
