I am a newbie and facing this issue.
i using Seeedunio v4.2, Base Shield and ESP8266.
I had tuned the volt to 3.3v and using jumper cable to connect between ESP8266 and base shield as you can see from the picture.
I can upload without issues. the only problem is
when i use putty to access, i do connect but i cannot able to send AT command to do further testing.
Can anyone enlightened me with some light?
i am not sure what i doing is correct
