I have a issue with the NodeMCU Lolin V3 board (i have 80 of them!)
I successfully did code on a Geekcreit® NodeMcu that uses the software serial libraries and it works perfectly!
When i compile and upload to the Lolin it wont read anything from the software serial. i have tried all the pins i could think of ive broken the code to the bare minimum just to do a serial read and none of them work,.,
ive spent weeks now googling and looking and trying but i just cant figure out why its not working??
Does someone have any idea why it works on one and not the other??
