IoT Stand

This solution is boilerplate structure that provides base microservices for:

• ARM based Board (Raspberry Pi 3, Toradex, Boundery Devices, etc.)
• MQTT based IoT Hub
• Self-hosted cloud server for client who communicated with devices in IoT Hub
• Example web client

---

ARM based Board

---

Requires

• Golang
• Linux (x86 or amd64)
• Any ARMv7 microcomputer board (Raspberry Pi 3, Toradex, Boundery Devices, etc.)
• Yocto Linux with QT
• Qt Open Source for Desktop
• Nats for Desktop&ARMv7

---

Microservices

• Telemetry Service [Golang] send any telemetry data (sensors, circels, temperature, etc.) to Cloud Service
• Cloud Service [Golang] - send any data to IoT hub based from MQTT protocol
• HMI Service [QT Quick] - user interface for sensor displays

All microservices communicate with NATS pub/sub and provides hight level abstract RPC API.

---

Build Yocto Linux

Build you board image with Yocto meta-boot2qt layer and Instructions.

---

Build Microservices

Run in terminal make deploy_device and see deploy_device folder.

Deploy all files to /deploy_device on your device with ssh.

Start systemd services (.service) and NATS ARMv7 service.

---

Development on local host machine

Use cmd/device/telemetry-service.go and cmd/device/telemetry-service.go for analyze of golang based microservice.

Use device/service/hmi for analyze of QT based microservice with Qt Creator.

For start all of microservices required NATS x86 or amd64 targets.

---

MQTT based IoT Hub, Websocket self-hosted Cloud server and Web client

---

Requires

• Golang
• Nats for Desktop
• Docker
• Docker Compose

---

Build

make build_server_side

See folder server_side_deploy.

---

Run

cd server_side_deploy

docker-compose up -d --force-recreate --build

or use ansible for remote server:

ansible-playbook -i YOUR_INVENTORY_FILE ansible/deploy.yaml

You can see result front-end based react app on port :80.

If you want analyze server-side code, see folder server/service/**.

If you want to analyze front-end code, see folder server/frontend/**.

Websocket service and MQTT service communicate with NATS pub/sub, provides hight level abstract RPC API and can be replicated with Kubernetes|Mesos|Swarm.
