Esp8266 and uno

How to send data between two arduino uno using esp8266 WiFi mpduke????

  1. What kind of data do you want to send?
  2. Did you try Google?
  3. A Beginner's Guide to the ESP8266.
  4. If you just want to send data between two Arduinos, the nRF24L01+ or a 433MHz transceiver could be better/easier options.

I want to send some text data to a long range.

Unless you have wireless access points nearby, WiFi is terrible for long ranges.

nRF24L01+'s with external antennas can cover well over a kilometer (outdoors without obstructions).
