SDK – iotconnect

SDK

The /IOTCONNECT™ SDK is how your device talks to the platform — it handles the connection, sending telemetry (device-to-cloud), and receiving commands (cloud-to-device). Start with the overview, understand the architecture, pick your language, and use the message references to build your device firmware.

Getting Started with the SDK

📘SDK OverviewWhat the SDK is, what it does for you, and how to get started integrating it into your device.	🏗️SDK ArchitectureHow the SDK is structured and how its layers connect your device to the cloud.	🧩Language TableSupported SDK languages and which features each one offers, so you can pick the right one.
⚙️SDK & Firmware ArchitectureHow the SDK fits into device firmware and the overall build.	📋Reference TableA quick reference of SDK fields, codes, and values you will use while building.

Message Formats & APIs

📨Device Message 2.1The current device message format for sending and receiving data.	📄Device Message 1.0The earlier message format, for devices still on version 1.0.	🔍Discovery APIThe first call a device makes to find its connection details.
🆔Identity APIHow a device identifies itself and gets its credentials.	📝Device Identity MessagesThe messages exchanged while a device identifies and syncs.

ⓘ NOTE

New to the SDK? Begin with SDK Overview, then choose your Language. Use Device Message 2.1 for new projects — 1.0 is only for existing devices still on that format.
