Zephyr IoT Protocols

Implement production-ready IoT communication using industry-standard mesh, wide-area, and cloud protocols.

Core Workflows

1. OpenThread Mesh

Build robust, low-power mesh networks using the integrated OpenThread stack.

• Reference: openthread_integration.md
• Key Tools: CONFIG_NET_L2_OPENTHREAD, otInstance, Thread Shell.

2. Matter-over-Thread

Create interoperable smart home devices using the Matter standard.

• Reference: matter_devices.md
• Key Tools: Matter Clusters, BLE Commissioning, ZAP tool.

3. Golioth Cloud SDK

Connect your fleet to the cloud for real-time state sync, telemetry, and OTA.

• Reference: golioth_sdk.md
• Key Tools: LightDB, golioth_system_client, remote logging.

4. LoRaWAN Basics

Deploy long-range, low-power sensor networks.

• Reference: lorawan_basics.md
• Key Tools: CONFIG_LORA, LoRa PHY, Adaptive Data Rate (ADR).

Quick Start (OpenThread Shell)

# Enable OpenThread with Shell
CONFIG_NET_L2_OPENTHREAD=y
CONFIG_OPENTHREAD_SHELL=y

# Join a network via Shell
ot dataset init new
ot dataset commit active
ot thread start

Professional Patterns (Ecosystem Design)

• Commissioning via BLE: Use the connectivity-ble skill patterns to handle Matter or Thread commissioning for a seamless user experience.
• Cloud-Mesh Gateways: Implement Thread Border Routers to bridge local mesh traffic to Golioth or other cloud backends.
• Battery Optimization: Use Sleepy End Device (SED) modes for Thread/LoRaWAN nodes to achieve multi-year battery life.

Automation Tools

• dataset_kv_check.py: Validate key/value provisioning datasets for required fields.

Examples & Templates

• thread_dataset_template.env: Starter Thread dataset values for development.

Validation Checklist

• OpenThread device forms or joins a mesh and maintains stable role/state.
• Matter commissioning completes and cluster interactions succeed.
• Cloud telemetry path (for example Golioth) delivers and receives expected state updates.
• LoRaWAN join and uplink/downlink flow work with expected data rate behavior.
