esp8266-deep-sleep-examples

This repository is a example code base demonstrating some aspects of ESP8266' ESP.deepSleep function for the Arduino platform. It results from my experiments when hacking on a DIY project.

When you tried deep sleep on an ESP8266 and wondered,

• where is my memory gone?
• why is the wifi not working as expected?
• are there some patterns for this stuff?

then please read on.

The examples do not come with a build system, but can be run using PlatformIO.

4 flavors:

• 01_default_nowifi: The bare minimum for playing with deep sleep
• 02_default_nowifi_retainvars: How to retain variables
• 03_default_wifi: Wifi
• 04_disablerf_wifi_retainstate, Wifi, extra power save by disabling RF
