Software Serial Esp8266 Tutorial
ESP8266 - Easiest way to program so far (Using Arduino IDE) 22 April 2015 on,Yep, another post on the ESP8266 is here (By the way, Have you heard about our already? Like us and get updates! We tend not to spam:P).It Seems like the ESP8266 community getting larger everyday and great people develop great tools to make the ESP8266 easier to use. (What is the ESP8266? Read some older posts:, ).The last projects were programmed using the, which creates a very simple operating system on the ESP8266 and let you write and execute LUA files. It has a lot of advantages which were described in those posts but some disadvantages as well such as memory problems and firmware bugs which the average user cannot resolve.Recently, some group from the ESP8266 forum published.
The code is an extension to the Arduino IDE which allows to flash programs to the ESP8266, making it kind of arduino compatible - HOORAY!As always, in order to try a new method I must decide on a new project which will encourage me to deal the new method with enthusiasm. The project I decided to build was a new code for the posted here a while ago. Reviewing the old post, I found its code more or less a 'proof-of-concept' code, where the emphasis was on the hardware.The project description in a few bullets:. The ESP8266 connects to my router via WiFi and serve as a web-client.
A website consists of a manageable SQL database with the schedule of the water heater with a main page for the user. The user can add/erase queries from the database.

Every 5 minutes the ESP8266 sends a GET request to the the website and receive the minutes left to turn ON/OFF the water heater. That way, even if the WiFi fails at some point the ESP8266 will still have the most updated schedule from the website. While sending the GET request, the website saves data of the time of request, the status of the GPIO and the ESP8266 IP address.

In the main page the user can see when was the last GET request and identify failures in the ESP8266. In case the user can't wait the 5 minutes, the ESP8266 serve as a server as well.

ESP8266SoftwareSerialBased on this library improves communication when using SoftwareSerial to comminucate between the Arduino and the ESP8266. IntroWe have modified the original library due to Software serial baudrate problems.Now, the init function, when using software serial only, will set the ESP8266 baudrate to 9600. Wiring You'll need:.
ESP8266.UsageSee example usage in Troubleshooting. If you receive partial response from the esp8266 when using software serial -go to C:Program Files (x86)ArduinohardwarearduinoavrlibrariesSoftwareSerialsrcSoftwareSerial.hChange line 42: #define SSMAXRXBUFF 64 // RX buffer sizeTo: #define SSMAXRXBUFF 256 // RX buffer sizethis will enlarge the software serial buffer. Sometimes setting the baudrate on initialization fails, try resetting the Arduino, it should work fine.
On some cases it might be necessary to flash the ESP's firmware. SeeFlashing the ESP. Use a 3.3v FTDI board like.
