I have tested the ESP8266 via the instructions listed in the tutorial in the Resources I've Used section below. set the data rate for the SoftwareSerial port Open serial communications and wait for port to open: The green wire is attached to pin 2 and the yellow wire is attached to pin 3. Same wiring as above, but I have RX and TX reversed. !! I have the green wire attached to pin 3 on the Arduino Uno and the yellow wire attached to pin 2 not 1 and 0 as the picture suggests !!
This is the results of running AT+GMR: AT version:0.40.0.0(14:45:58) I have found that I can communicate with the ESP8266 at 115200 baud. Using the Arduino as a pass through (as explained in the tutorial listed in the resources section), I can send AT commands. I either send AT commands and get nothing back ( wiring scheme 1) or I send AT commands and get garbage back ( wiring scheme 2). From Arduino UNO, send AT commands to ESP8266 via a SoftwareSerial port and receive results.
