Digi’s Wi-SUN solution provides a flexible communication framework based on standard interfaces for data exchange and device configuration.

This section collects the technical reference information for these interfaces, detailing the supported communication frames and command structures used within these networks.

Overview

The Digi Wi-SUN solution relies on two key mechanisms to manage and exchange information between the devices that form the network:

  • API frames: Structured data packets that define how to send, receive, and interpret information such as network data, configuration parameters, and diagnostic results.

  • AT commands: Commands used to configure and query device settings directly. They provide a simple, human-readable interface for managing network parameters, connection status, and device behavior.

These two interfaces are complementary since API frames are typically used for automated or programmatic control, while AT commands are used for manual configuration and testing.

For complete details on each interface, refer to the following sections:
