Hi everyone,
I got struck in middle of my task. I trying to connect Arduino(UNO) TX and RX pin directly to ESP8266 RX and TX pins instead of using Software serial library with different digital pins. Now the thing is ESP8266 is responding as showing error message in serial monitor. Can anyone help me in solving this problem. My goal is to make communicate ESP8266 with Arduino TX and Rx pins without software serial library and ftdi cable.
----Thanks for the Help!!!
Particle.io board. Particle.io’s web site and browser based IDE. Pushes the new program across internet and to WiFi and into the 8266. Instead of slow FTDI/serial.

Don’t do that without using a way to levelshift the voltage from the pins (like these https://www.sparkfun.com/products/12009; or just a voltage divider between UNO TX and ESP RX). The 5 volt of the Uno can kill the 3.3 volt pins of the ESP8266. Looking at the following it may already have.
Now the thing is ESP8266 is responding as showing error message in serial monitor.
What is the error message?
