Deara all , i m a newbie with a Sparkfun ESP8266 Dev connected through a USB port to my MAC running Arduino IDE 1.85 .
My help request today is that i cannot connect to a valid port . Re installed the CH340 driver , but it does not work . By the way works fine with NodeMCU Esp8266 . Any help is welcome !! Thank you very much

The Thing Dev uses a FTDI chip rather than a CH340 so you will need the FTDI driver instead.
