Sample repository for working with ESP-IDF on AWS IoT with the ESP32

ESP-IDF AWS IoT

Steps

• Install PlatformIO Core

• Create a device and export the three certificates to:

  • src/aws-root-ca.pem: Retrieve from HERE
  • src/private.pem.key: Private Key Certificate
  • src/certificate.pem.crt: Device Certificate

• Update #define CONFIG_AWS_IOT_MQTT_HOST "xxxxxxxxxxxxx-ats.iot.us-east-1.amazonaws.com" in sdkconfig.h

  • Run aws iot describe-endpoint --endpoint-type iot:Data-ATS to get address

• Update build_flags in platformio.ini

  • -DCONFIG_WIFI_SSID=\"wifissid\"
  • -DCONFIG_WIFI_PASSWORD=\"wifipass\"
  • -DCONFIG_AWS_IOT_TOPIC=\"test_topic/esp32\"

• Run these commands:

  # Build project
  platformio run
  
  # If you get an error `Kconfig.projbuild' not found (in 'source "$COMPONENT_KCONFIGS_PROJBUILD"').`, run this command
  pip3 uninstall kconfiglib
  
  # Upload firmware
  platformio run --target upload

esp-idf-aws-iot's Issues

Issues when building

Hi mate,

To start with, I just want to say great article and example code so I want to give some feedback for others that will try it out. I noticed that the link in the article https://devopstar.com/2020/03/14/easy-aws-iot-with-esp-idf for AWS IoT documentation page is pointing to the github repo and not to the aws docs.

Another thing I bumped into was when building, it looks like its not possible to build due to the headers / lib it tries to fetch. Attaching the output from the build bellow

Btw, I did test https://github.com/platformio/platform-espressif32/tree/master/examples/espidf-aws-iot and that one works
