Wireless Smart Ubiquitous Network (Wi-SUN) is the leading IPv6 sub-GHz mesh technology for smart city and smart utility applications. Wi-SUN brings Smart Ubiq-uitous Networks to service providers, utilities, municipalities/local government, and other enterprises, by enabling interoperable, multi-service, and secure wireless mesh networks. Wi-SUN can be used for large-scale outdoor IoT wireless commu-nication networks in a wide range of applications covering both line-powered and battery-powered nodes. Silicon Labs’ Wi-SUN hardware is certified by the Wi-SUN Alliance, a global indus-try association devoted to seamless LPWAN connectivity. Wi-SUN builds upon open standard internet protocols (IP) and APIs, enabling developers to extend existing infrastructure platforms to add new capabilities. Built to scale with long-range capabilities, high-data throughput and IPv6 support, Wi-SUN simplifies wire- less infrastructure for industrial applications and the evolution of smart cities.

Compatibility and Use Notices

For information about security updates and notices, see the Security chapter of the Gecko Platform Release notes installed with this SDK or on the TECH DOCS tab on https://www.silabs.com/developers/wi-sun-protocol-stack. Silicon Labs also strongly recommends that you subscribe to Security Advisories for up-to-date information. For instructions, or if you are new to the Silicon Labs Wi-SUN SDK, Using This Release.

Compatible Compilers:

IAR Embedded Workbench for ARM (IAR-EWARM) version 9.40.1

• Using wine to build with the IarBuild.exe command line utility or IAR Embedded Workbench GUI on macOS or Linux could result in incorrect files being used due to collisions in wine’s hashing algorithm for generating short file names.
• Customers on macOS or Linux are advised not to build with IAR outside of Simplicity Studio. Customers who do should carefully verify that the correct files are being used.

GCC (The GNU Compiler Collection) version 12.2.1, provided with Simplicity Studio

Wi-SUN Stack

This release of the Gecko SDK (GSDK) will be the last with combined support for all EFM and EFR devices, except for patches to this version as needed. Starting in mid-2024 we will introduce separate SDKs:

• The existing Gecko SDK will continue with support for Series 0 and 1 devices.
• A new SDK will cater specifically to Series 2 and 3 devices.

The Gecko SDK will continue to support all Series 0 and 1 devices with no change to the long-term support, maintenance, quality, and responsiveness provided under our software policy. The new SDK will branch from Gecko SDK and begin to offer new features that help developers take advantage of the advanced capa-bilities of our Series 2 and 3 products. This decision aligns with customer feedback, reflecting our commitment to elevate quality, ensure stability, and enhance performance for an exceptional user experience across our software SDKs.

New Items

Added in release 1.9.0.0

• Added support for ETSI Adaptive Power Control. It is required to comply with Indian regional regulations.
• Improved LFNs clock drift compensation. It reduces the power consumption and the connection stability.
• Dropped the high-reliability transmission mechanism. Its use was not recommended, and it was causing a significant increase of all communication latency

Added in release 1.8.0.0

• Added a new API sl_wisun_get_stack_version() that returns the stack version.
• Updated sl_wisun_join() to support the customization of PHY configurations. Extended sl_wisun_phy_config_type_t and sl_wisun_phy_config_t to allow the customization of OFDM, FSK and O-QPSK entries.
• Added support for LFN Timing Offset (LTO). Avoid LFN broadcast and unicast overlaps.
• Added support for LFN multicast reception.
• Added support for SUN DSSS-OQPSK.
• Added support for blocking sockets.
•  Added support for the new Indian PHY configurations.

Improvements

Changed in release 1.8.0.0

• Refactored the socket API. The POSIX socket API is used to call Silicon Labs socket API. The logic is now reversed. Silicon Labs socket API became a wrapper around the POSIX socket API that is now exposed by the stack.
• Removed the RTOS dependencies from the libraries.

Fixed Issues

• Fixed in release 1.9.0.0

packets with an empty payload.
1225947| Fixed an error causing the frequency hopping to be blocked on rare occasions.
ID #| Description
---|---
1234624| Fixed an error causing LLC messaging allocation to fail. It was caused by an invalid logic in the mac TX queue.

1246610| Fixed an error causing LFNs reconnection to a router to fail.
1234620| Fixed an error preventing LFNs to send NS(EARO) and thus to reconnect after a given number of non- consecutive unsuccessful connection attempts.
1244154| Fixed an error causing an invalid memory access in dense topologies.
1235265| LUS-IE were sent in all LFN data frames, even when the Listen Interval did not change.
