Need help connecting to Cayenne with ESP8266

If I remember correctly, the None on COM11 should be fine. Maybe just double check to see that the UART device is on COM11, but if the sketch is uploading to the ESP then you have nothing to worry about.

The connection type is where your issue is. See this post for a walk through on setting up the ESP.

It’s interesting that your router shows the ESP, but that could just be an old DHCP lease from a previous connection you made.
