ESP8266 Community Forum

hello i am new with the ESP8266 and i don't have any idea !!!
Yesterday came my order with 3x ESP8266 i try to connecting with much different ways but nothing happened !!

i am 101% sure i have the correct connection but i don't take any answer from the arduino !!

i have see the pcb soldering is little bit strange... is this soldering right ??
its same all 3 smell like CHINA

Thank you !!!

Although those solderings look bad, the modules maybe working any way.
When you try them out thru your Arduino, did you sent AT commands follow with CR+LF, not only CR ?

Thank you for your answer !!
Both don't work..
When I connect it to the arduino I don't take nothing like " ready " or other answer from board..

Hi, with some of the Arduinos the Tx and Rx are the connection that you should connect to, not the names of the pins.

With most other stuff:
Tx -> Rx
Rx -> Tx

With some Arduino:
Tx -> Tx
Rx -> Rx

As if life wasn't hard enough without complications. See if that helps.
