Just purchased a ESP8266 board (WeMos) and am trying to set it up.
I have installed the Board with Board Manager, but I can't get the wired COM port to populate under Tools so I can upload a sketch.
Also installed the CH340G driver, but still can't get it to work.
I am using a Mac with iOS High Sierra.
Make sure your USB cable is fully inserted into the Arduino board and the computer.
You may be using a charge-only or defective USB cable. Try a different cable or test your cable on another device to confirm that it works for data.
Ahh good point. I'll give it a go this evening.
Yup! that worked.
Was using the wrong USB cable.
You're welcome. I'm glad to hear it's working now. Enjoy!
