Wi-SUN SDK 1.5.2.0 GA Wireless Smart Ubiquitous Network
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 Ubiquitous 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 communication 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 industry 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 wireless 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, see Using This Release.
Compatible Compilers:
IAR Embedded Workbench for ARM (IAR-EWARM) version 9.20.4
- 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 10.3-2021.10, provided with Simplicity Studio.
Wi-SUN Stack
New Items
Added in release 1.5.0.0
- Added a new SL_WISUN_SOCKET_OPTION_SEND_BUFFER_LIMIT socket option to configure the transmission buffer length. It is the equivalent of Posi SO_SNDBUF.
- Added a new SL_WISUN_PHY_CONFIG_IDS option in sl_wisun_join. It allows the selection of a specific radio configuration entry.
- Implemented LFN parent synchronization and time-out detection.
- Implemented LFN EAPOL accelerated listening schedule.
Added in release 1.4.0.0
- Added minimal support for FAN1.1 LFN (Limited Functional Node). LFN devices are able to connect and communicate but are not using any of the EFR32 energy management mode. As such, they are not optimized for battery powered devices and should only be used for evaluation and experimentation.
- Added a new API sl_wisun_set_device_type()that configures the role of device. It can be either a router (FFN – Full Functional Node) or an end node (LFN)
- Added a new set of libraries supporting both LFN and FFN device types. Those libraries are used when the new “Stack LFN Support” plugin is installed.
- Added support for FAN 1.1 PHY mode switch.
- Added a new API sl_wisun_set_mode_switch() that indicates if the device can mode switch with a given neighbor.
- Added new APIs sl_wisun_get_pom_ie()and sl_wisun_get_pom_ie() that write or read the content of the POM-IE (PHY Operating Mode Information Element). It contains the list of the PHY operating mode a node is willing to use for communication.
- Added a new API sl_wisun_join() that triggers a new connection. It can be used either with the old (1V08 – regulatory domain, operating class, operating mode) or the new (1VA8 – regulatory domain, channel plan id, PHY mode if) nomenclature. That new API is meant to replace sl_wisun_connect().
- Added a new API sl_wisun_set_connection_parameters() that extends the set of the configuration parameters. Used in pair with sl_wisun_join(), it replaces sl_wisun_connect() network size parameter.
- Added support for FSK FEC. FEC can be enable either by setting fec field of sl_wisun_phy_config_t structure or by using a PHY mode id that explicitly enables FEC.
- Added support of EFR32FG25. It supports all FAN1.1 OFDM modulation schemes and all FAN1.0 FSK configurations.
- Added support of EFF01
Improvements
Changed in release 1.5.1.0
- Reduced the NS(EARO) retry period during the first connection. It reduces the time to connect in case of retransmission and improves the process’s reliability.
Fixed Issues
Added in release 1.5.2.0
| ID # | Description |
|---|---|
| 1078034 | Fixed an RNG error that could happen on EFR32xG12. |
| 1112966 | Fixed an error causing LPA to be missed on PHY configurations using a |
lot of channels.
1107537| Fixed an error causing a segmentation fault on congested networks.
1098801| Unencrypted LPC were accepted by LFN when they shouldn’t have been.
1094861| Fixed FEC support in Linux Border Router RCP.
Fixed in release 1.4.0.0
| ID # | Description |
|---|---|
| 1078454 | The wrong radio entry could be used if a radio configuration file |
contained the same PHY more than once. It was always selecting the first
entry found that matched the PHY characteristics. It was causing a single PHY
to be selected instead of a multi-PHY and made the use of mode switch
impossible.
1090805| Fixed timing drift calculation error that would lead to temporary
desynchronization of broadcast frequency hopping.

GSDK installation. Simplicity Studio 5 includes everything needed for IoT
product development with Silicon Labs devices, including a resource and
project launcher, software configuration tools, full IDE with GNU toolchain,
and analysis tools. Installation instructions are provided in the online
Simplicity Studio 5 User’s Guide.
Alternatively, Gecko SDK may be installed manually by downloading or cloning
the latest from GitHub. See https://github.com/SiliconLabs/gecko_sdk for
more information.
Simplicity Studio installs the GSDK by default in:
- (Windows): C:\Users\
\SimplicityStudio\SDKs\gecko_sdk - (MacOS): /Users/
/Simplicity Studio/SDKs/gecko_sdk
Documentation specific to the SDK version is installed with the SDK.
