yes i've tried it but if i set SoftwareSerial(RX,TX) , and if i send data, it is working but i getting data on TX port... So strange ... If i change the pins number [to something], situation is the same... RX doesn't work...
Obviously, it doesn't work because of something.
When you get a sketch like "Serial Input Basics" running on the Arduino, try it on the ESP8266. Then show us the code and data that does and/or doesn't work.
