Arduino IDE used to allow me to choose between 2 or 3 serial ports each with an esp8266 attached.
ARDUINO IDE 1.8.13
There does not appear to be a place to set /dev/ttyUSB1 as my upload port.
I have two esp8266 attached to a raspberry pi 3 b +
I tried altering preferences.txt to ttyUSB1 but it didnt change the upload port.
Thanks! Bradshaw in Buzzards Bay (MA)
port /dev/ttyUSB0 works perfectly, how may I choose /dev/ttyUSB1 ?
