ESP8266 Tips

Last updated: 2017 Feb 12th

This is a list of tips and tricks for the ESP8266 module. I will update this page as I learn more about these chips. Pull requests are appreciated.

Communities

Where to look for help and support.

• ESP Community forums
• Gitter for ESP8266 - A group chat for the ESP8266 and the Arduino libary.
• Stackoverflow, and electronics.stackexchange are great for asking questions.

Documtation

• Debugging ESP8266 Arduino - Instruction on how to set up the Arduino IDE to debug the ESP8266 Arduino libary.

Youtube

• Andreas Spiess ESP8266 series. - Great youtube series of videos about the ESP8266. Highly suggested

Libaries

• ESP8266 Arduino Libary
• WiFiManager - ESP8266 WiFi Connection manager with fallback web configuration portal
• WIZ Ethernet Library - A fork of the WIZ_Ethernet_Library that supports Wiznet 550io Ethernet board. (Created by me)

Power consumption

• Under normal operation the ESP8266 chip consumes around 70mA at 3.3v with spikes of 300mA. These spikes are really anying while building a power supply. A 1000-2200uF cap and reduce these spikes. Source: #47 Power Saving with ESP8266.

• The ESP.deepSleep() function doesn’t work unless there is a delay of 100 after this command.

  ESP.deepSleep(1000*10000*3, WAKE_RF_DEFAULT) ; 
  delay(100); 
  

• In deep sleep the ESP consumes around 0.06mA
