CC2 Device Documentation

Getting Started with CC2

Welcome to the Infrafon CC2 Developer Getting Started Guide. This document guides you through connecting your CC2 device, understanding MQTT downlink/uplink topics, and deploying your first custom DataView screen.

Prerequisites

Section titled “Prerequisites”

Before starting, ensure you have:

  1. An Infrafon CC2 Device (serial / EUI number).
  2. Credentials to an MQTT Broker (TLS supported on port 8883).
  3. Access to the Dataview Designer.

Step 1: Connect Device to Network

Section titled “Step 1: Connect Device to Network”
  1. Power on the CC2 device.
  2. The device enters Unallocated State (U) if not yet assigned to an organization.
  3. Configure Wi-Fi or LoRaWAN network parameters over USB CLI or provisioning payload.
  4. Verify connection status in the top status bar (Wi-Fi / MQTT icon turns solid).

Step 2: Understand MQTT Topics

Section titled “Step 2: Understand MQTT Topics”

CC2 communicates using strict MQTT topic paths:

Downlinks (Cloud -> Device)

Section titled “Downlinks (Cloud -> Device)”
infrafon/cc2/{devid}/downlink/dev-config
infrafon/cc2/{devid}/downlink/app

Uplinks (Device -> Cloud)

Section titled “Uplinks (Device -> Cloud)”
infrafon/cc2/{devid}/uplink/dev-data
infrafon/cc2/{devid}/uplink/app

Step 3: Deploy Your First DataView

Section titled “Step 3: Deploy Your First DataView”
  1. Open Dataview Designer.
  2. Drag and drop widgets (Text String, Graphic Icon, Progress Bar).
  3. Export the generated JSON payload.
  4. Send the DataView JSON over MQTT downlink:

    • Topic: infrafon/cc2/{devid}/downlink/app

    • Payload:

      {
        "cmd": "show",
        "dataview": { ... }
      }

The CC2 screen updates immediately.
