  • The ESP8266 I recently received from SparkFun is running version 0.9.5 of the AT firmware with a baud rate of 115200. This was too fast for my Arduino (especially for software serial). To lower the baud rate to 9600 I had to connect it to my computer via FTDI and send it the command AT+CIOBAUD=9600. Also, the wiki link in the Documents section labels the inner pins as "NC". This is incorrect. The pins are labeled correctly at http://www.electrodragon.com/w/File:ESP8266_V091.png. Make sure to connect the CH_PD pin to VCC. I had to discover this via a lot of searching and trial and error. Hopefully this saves someone some time.

  • Thanks Blizzrad. I am running my ATMega8 at 1MHz and was getting garbage printed to the terminal. I switched to 2400bps and updated FOSC and BAUD settings. Now it is working great.

No public wish lists :(
