Bluetooth mesh is a new topology available for Bluetooth Low Energy (LE) devices that
enables many-to-many (m:m) communication. It's optimized for creating large-scale device networks, and is ideally suited for building automation, sensor networks, and asset
tracking. Our software and SDK for Bluetooth development supports Bluetooth Mesh and
Bluetooth 5 functionality. Developers can add mesh networking communication to LE devices such as connected lights, home automation, and asset tracking systems. The software also supports Bluetooth beaconing, beacon scanning, and GATT connections so
Bluetooth mesh can connect to smart phones, tablets, and other Bluetooth LE devices.

Compatibility and Use Notices
If you are new to the Silicon Labs Bluetooth mesh SDK, see Using This Release.
Operating System Compatibility
Please contact support if you are developing on macOS 10.14 or newer. An issue with code signing prevents using bgbuild and bgtool
binaries on those OS versions.
Compatible Compilers:
IAR Embedded Workbench for ARM (IAR-EWARM) version 8.30.1
•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 7.2.1, provided with Simplicity Studio.
•Link-time optimization feature of GCC has been disabled, resulting in slight increase of image size

1.1 New Features
Added in release 1.7.2. 0
Support for HSL models (HSL clien t, H SL server, HSL setup s erver, H SL hue se rver, H SL saturation ser ver) has been added as an alpha
release.
Added in release 1.7.1. 0
Model qualification listing updated to include Time and Scheduler models
Added in release 1.7.0.0
Added support fo r EFR32[B|M]G22 and Thunderboard E FR32BG22 hardware. Note that the limited am ount of RAM on [B|M]G22 devices
restricts their use in som e role s th at may need comparativ ely l arge a mou nts of m emo ry , such as relays, GATT proxies, and provisioners.
[B|M]G22 devices are, however, well suited for battery-powered operation. Of the SDK example applications, SoC empty, SoC switch,
SoC sensor client and SoC sensor server are supported on [B|M]G22 devices.
Support for scheduler models (Scheduler client, Scheduler server, Scheduler setup server) has been added as an alpha release.
A ne w memor y co nfi gur at ion v alu e for sett in g the application message queue length length has been added. The application message
queue is used for delayed application messages, such as status responses.
1.2 New APIs
For additional documentation please refer to the Bluetooth Mesh So ftwa re API R eference Manual i nstalled with the Bluetooth Mesh S DK .
Added in release 1.7.0.0
BGAPI commands and ev ent s f or Scheduler models have been added . Note that Scheduler model functionality has been released as an
alpha release.
Scheduler client model commands and events added:
mesh_scheduler_client_init(),
