Steps to compile Domain Tech Summit 2019 Workshop firmware for ESP32

  1. Clone the repo:
git clone https://github.com/yona75/dts2019-workshop
  1. Navigate to ~/environment/esp/dts2019-workshop/tools/aws_config_quick_start/ and open file configure.json Edit you Thing name, WiFi credentials, and WiFi security mode which should be eWiFiSecurityWPA2

Edit configure.json

  1. Save the file

  2. In the Terminal window navigate to ~/environment/esp/dts2019-workshop/tools/aws_config_quick_start and execute python SetupAWS.py setup command to provision your Thing, Certificate, and Policy:

cd ~/environment/esp/dts2019-workshop/tools/aws_config_quick_start 
python SetupAWS.py setup

If successful command will not produce any output, but you can verify in AWS IoT Core Console that new Thing, Certificate and Policy were created.

  1. In the Terminal window navigate to ~/environment/esp/dts2019-workshop/demos/espressif/esp32_devkitc_esp_wrover_kit/make and execute make menuconfig command:
cd ~/environment/esp/dts2019-workshop/demos/espressif/esp32_devkitc_esp_wrover_kit/make 
make menuconfig
  1. Click Save and then Exit

make menuconfig

  1. Execute make command
make
  1. Once compilation is done, download these 3 files to your local computer:
  • build/aws_demos.bin
  • build/partitions_example.bin
  • build/bootloader/bootloader.bin

download bin files from Cloud9

  1. Flash the firmware and observe console output as described in Uploading compiled firmware to ESP32 development board

  2. In the Terminal window navigate back to ~/environment/esp/dts2019-workshop and execute git checkut shadow-demo command:

cd ~/environment/esp/dts2019-workshop 
git checkout shadow-demo

You are now in the shadow-demo branch

  1. Navigate to ~/environment/esp/dts2019-workshop/demos/espressif/esp32_devkitc_esp_wrover_kit/make and execute make command:
cd ~/environment/esp/dts2019-workshop/demos/espressif/esp32_devkitc_esp_wrover_kit/make 
make
  1. Once compilation is done, delete old aws_demos.bin, partitions_example.bin, and bootloader.bin from YOUR LAPTOP!!! and download again these 3 files to your local computer (If you will not delete or move old files on Mac they will be downloaded as aws_demos (1).bin, etc.):
  • build/aws_demos.bin
  • build/partitions_example.bin
  • build/bootloader/bootloader.bin

  1. Flash the firmware and observe console output as described in Uploading compiled firmware to ESP32 development board section

  2. In AWS Console navigate to AWS IoT Core -> Manage -> -> Shadow Observe the sensors output

  3. Edit the desired section of the demo to set LED colors (Insert this BEFORE reported section)

  "desired": {
    "leds": [
      {
        "red": 16,
        "green": 0,
        "blue": 0
      },
      {
        "red": 0,
        "green": 15,
        "blue": 0
      },
      {
        "red": 0,
        "green": 0,
        "blue": 15
      },
      {
        "red": 15,
        "green": 15,
        "blue": 0
      },
      {
        "red": 0,
        "green": 15,
        "blue": 15
      }
    ]
  },
