ESP8266 Community Forum

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?

Thank you.

Yup i had tried all baud rate but still unsuccessfully. i am wonder that is it my connecttion is wrong or it cannot go thru groove.
