AWS IoT with ESP8266 Demo

Example sending data from ESP8266 to AWS IoT Core.

Getting Started

Add the ESP8266 board to Arduino IDE (Files > Preferences, then paste the URL in Additional Boards Manager):

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Versions:

• Arduino: 1.8.12
• ESP8266 core: 2.6.3
• ESP8266FS plugin: 0.5.0

Install the following libraries (Sketch > Include Library > Manage Libraries):

• PubSubClient 2.7.0
• ArduinoJson 6.15.1

AWS IoT Certificates

Convert the certificates from AWS to .der files, then place them in data/ (within the Arduino sketch folder). Use the arduino-esp8266fs-plugin to upload the files to the SPIFFS filesystem.

openssl x509 -in xxx-certificate.pem.crt -out cert.der -outform DER
openssl rsa -in xxx-private.pem.key -out private.der -outform DER
openssl x509 -in AmazonRootCA1.pem -out ca.der -outform DER
