Mongoose OS demo for AWS IoT

Prerequisites:

1. MongooseOS CLI and IDE mos
   • https://mongoose-os.com/software.html
   • https://mongoose-os.com/docs/quickstart/setup.html
2. AWS CLI aws
   • https://aws.amazon.com/cli/
3. Terraform for building the AWS stack terraform
   • https://www.terraform.io/downloads.html
4. Android Studio for the Android application
   • https://developer.android.com/studio/
5. Download the Greengrass software for EC2 x86_64 packages: https://docs.aws.amazon.com/greengrass/latest/developerguide/gg-config.html

Setup:

Warning the below setup is not for production usage!

If you wish to use MongooseOS UI you can run mos ui within the project directory.

1. Set up terraform for AWS: terraform init
2. Set up stack using terraform: terraform apply
3. Configure the mos.yml with the output of relevant terraform apply and your wifi setup. You will also need to change the thing to the name outputted by terraform: ["aws.thing_name", "IOT_DEVICE_1"]
4. Build the firmware according to your device: mos build --arch esp8266 or mos build --arch esp32
5. Flash device: mos flash
6. Setting up AWS config for device: mos aws-iot-setup --aws-region <Region> --aws-iot-policy mos-default
7. Check device logs to see AWS updates: mos console you should get logging similar to below.
8. Setup the optional Android management application with the terraform output

Log outputs:

[Jul 23 15:40:34.451] Published: yes topic: devices/esp8266_7A0349/data message: {"humidity":"80","temp":"20","device":"esp8266_7A0349"}

You can also edit the mos.yml file to configure device setup

Limitations and Issues:

• AWS still has limited Cloudformation APIs for IoT and Greengrass
• Terraform has even less support
• Make sure mos is updated run: mos update latest
