aws-iot-esp32-arduino-examples's Introduction

AWS IoT + esp32

This project contains several Arduino examples for AWS IoT projects using ESP32 Wi-Fi+BLE based development modules.

Arduino support for ESP32 modules can be found here.

For each example you will need to register an AWS IoT device and create credentials.

Each example has a "secrets.h" file where Wi-Fi and device credentials are to be stored.

Required Parameters:

WIFI_SSID: The name of the Wi-Fi network to connect to. Should not include special characters or spaces.
WIFI_PASSWORD: The password of the Wi-Fi network to connect to.
THINGNAME: Must match the name of the device in the AWS IoT console.
AWS_IOT_ENDPOINT: The endpoint associated with your AWS IoT Core account.
AWS_CERT_CA: Amazon Root CA 1
AWS_CERT_CRT: AWS IoT Thing Certificate
AWS_CERT_PRIVATE: AWS IoT Thing Private Key

Required Arduino Libraries:

Examples:

basic-pubsub: Connects to AWS IoT. Demonstrates subscribing to and publishing to topics. Works great with the lambda-iot-rule serverless application.
thermal-printer: Connects to AWS IoT and subscribes to a topic. Prints messages out to a physical receipt printer.
spectral-sensor: This example connects a Sparkfun Spectral Triad (AS7265x) sensor to an Arduino connected to AWS IoT. This sensor examines light absorption on various wavelengths across IR, UV, and visible light. These values can be used to detect different materials.

M5Stick Examples:

m5stick-lcd: Connect an M5Stick to AWS IoT and display messages on its built in LCD.
m5stick-env: Publish magnetic compass heading, temperature, barometric pressure, and humidity to AWS IoT using an M5Stick with the ENV hat module.

How can I publish data to shadow?

Hello dears,

Good afternoon, I hope you are well.

I would like to ask for help to be able to publish sensor data through the shadows ... I have read the information but unfortunately I do not understand ... could you help me?

I would really appreciate it.

Thanks for your understanding.

Formatting the Certificate array in secrets.h

I've created a sample program using the same construct for the certificate array in an AVR studio project.
I see 0x0A added into the array at every end of line.
I believe quotes should be used on each line together with the \ character.

Can you add an OTA example to the lib.

It will be great to add an OTA example to the library.

Use JITP rather than hardcoding device cert in firmware

Using Arduino, how would one have a single firmware image to flash to many devices?

In other words, I do not want to hardcode and compile a dedicated firmware for each device. That is firstly a lot of admin and work, but also makes sending out OTA firmware updates almost impossible.

If I understand correctly the recommended way to do this is to use Provisioning by claim. Also known as JITP.

How would one do this in Arduino?

Sugestion / Request - SimpleExample.ino to ESP8266 not working

The sample SimpleExample.ino is not working because TLS 1.2 is required
And the others samples now use files in SPIFFS with certificates.
Please update the sample

(docs): basic-pubsub serverless app not found

This part of README.md points to an AWS Serverless App Repository which seems to be inaccessible. The link returns the message:
The application you were looking for could not be found. Return to the applications search page.

Examples:

basic-pubsub: Connects to AWS IoT. Demonstrates subscribing to and publishing to topics. Works great with the lambda-iot-rule serverless application.

Things I tried:

Following the link directly from the guide here
Searching the SAR for "lambda-iot-rule" and other variations.

I have an AWS support ticket open for this and will report back when I get a response.

Follow up
AWS support classified this as a technical issue, which is strange because the app is missing from the SAR entirely.

I will start a repo in CDK that aims to recreate the deployment process. Please leave a comment if you would like to assist me.
