ESP8266 IoT Helper

This library contains a simple helper that you can orchestrate WiFi connection via SmartConfig and Arduino IDE + HTTP OTA update features all together.

How to use

Instantiate helper with valid HTTP OTA information:

ESP8266IoTHelper iotHelper("<HTTP OTA Server Host>", <HTTP OTA Server Port>, "<HTTP OTA Server Path>")

or with only SmartConfig and Arduino IDE OTA updates capability:

ESP8266IoTHelper iotHelper

Then in your setup function initialize it:

iotHelper.initialize()

And on your loop function call execute (preferably the first line):

iotHelper.execute()

What does it do

Initialize

• Tries to connect WiFi with your previosly saved WiFi configuration. If can not connect WiFi, starts SmartConfig.

• Sets up Arduino IDE OTA and HTTP OTA updates and checks for OTA updates if valid configuration supported.

Execute

• Checks if the SmartConfig input pin is active (HIGH or LOW as your config) if enabled by configuration and if pin is active then starts SmartConfig.

• Checks if Arduino IDE OTA updates available.

• Checks HTTP OTA updates if valid configuration supported.
