Bluetooth® mesh SDK 7.0.0.0 GA
Simplicity SDK Suite 2024.6.0 June 5, 2024

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 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.
This release includes features supported by the Bluetooth mesh specification version 1.1.
These release notes cover SDK versions:

KEY FEATURES
· Migration to Simplicity SDK Suite · Removed support for Series 0/1

7.0.0.0 released June 5, 2024

Compatibility and Use Notices
For more information about security updates and notices, see the Security chapter of the Platform Release Notes installed with this SDK or on the Silicon Labs Release Notes page. 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 Bluetooth mesh SDK, see 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. · Link-time optimization feature of GCC has been disabled, resulting in a slight increase of image size.

Simplicity SDK is an embedded software development platform for building IoT products based on our Series 2 and Series 3 wireless and MCU devices. It integrates wireless protocol stacks, middleware, peripheral drivers, a bootloader, and application examples ­ a solid framework for building power-optimized and secure IoT devices. The Simplicity SDK offers powerful features such as ultra-low power consumption, strong network reliability, support for a large number of nodes, and abstraction of complex requirements like multiprotocol and pre-certification. Additionally, Silicon Labs provides over-the-air (OTA) software and security updates to remotely update devices, minimize maintenance costs, and enhance the end-user product experience. Simplicity SDK is a follow-on from our popular Gecko SDK, which will continue to be available providing long-term support for our Series 0 and Series 1 devices. For additional information on the Series 0 and Series 1 devices please reference: Series 0 and Series 1 EFM32/EZR32/EFR32 device (silabs.com).
1.1 New Features
Added in release 7.0.0.0 Support for Clock Manager has been added. The stack components no longer use device_init() for clock initialization. Instead, the application project must now include the clock_manager component which does the clock initialization. Support for Common Memory Manager has been added.
1.2 New APIs
Added in release 7.0.0.0 None.

Improvements
2 Improvements
Changed in release 7.0.0.0 BGAPI changes: A node BGAPI class command, sl_btmesh_node_test_identity, has been added for checking whether a received node identity advertisement originates from a given node or not.
Example application changes: Low Power Node feature has been added to Sensor server examples (btmesh_soc_sensor_thermometer, btmesh_soc_nlc_sensor_occupancy btmesh_soc_nlc_sensor_ambient_light), and Friend feature was added to the sensor server client example (btmesh_soc_sensor_client).

Fixed in release 7.0.0.0

ID # 356148 1250461 1258654 1274632
1284204

Description Avoids starting advertisement bearer if node is being provisioned using only PB-GATT. Made provisioning event reporting more robust on an overloaded device. Made DFU event reporting more robust on an overloaded device. DFU Distributor and Standalone Updater models will now report an error if Blob Transfer configuration on the node is not sufficient. Fixed saving replay protection to NVM3 when application uses the sl_btmesh_node_power_off() API.

Known Issues in the Current Release

4 Known Issues in the Current Release

Issues in bold were added since the previous release.

ID # 401550 454059 454061 624514 841360
1121605 1226127 1204017 1301325 1305041 1305928

Description No BGAPI event for segmented message handling failure.
A large number of key refresh state change events are generated at the end of KR process, and that may flood NCP queue. Slight performance degradation compared to 1.5 in round-trip latency tests was observed. Issue with re-establishing connectable advertising if all connections have been active and GATT proxy is in use. Poor performance of segmented message transmission over GATT bearer.
Rounding errors may cause scheduled events to trigger at very slightly different times than expected. Host provisioner example can be stuck when it starts to provision a second node. Distributor is not able to handle parallel self FW Update and FW Upload. Scheduler actions are not correctly stored to persistent storage. NCP communication from host to EFR32 may timeout. Setting up 10 or more updating nodes as DFU receivers may fail on the SoC distributor app.

Workaround Application needs to deduce failure from timeout / lack of application layer response; for vendor models an API has been provided. Increase NCP queue length in the project.
Allocate one more connection than is needed.
Ensure that the underlying BLE connection's Connection interval is short; ensure that ATT MTU is large enough to fit a full Mesh PDU; tune the minimum connection event length to allow multiple LL packets to be transmitted per connection event.
Restart the host provisioner app before provisioning the second node. Don't run self FW update and FW upload in parallel.
sl_simple_com_usart.c may be edited to correct a timeout value.

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, Simplicity SDK may be installed manually by downloading or cloning the latest from GitHub. See https://github.com/SiliconLabs/simplicity_sdk for more information .
Simplicity Studio installs the Simplicity SDK by default in: · Windows: C:\Users\<NAME>\SimplicityStudio\SDKs\simplicity_sdk · MacOS: /Users/<NAME>/SimplicityStudio/SDKs/simplicity_sdk
Documentation specific to the SDK version is installed with the SDK. Additional information can often be found in the knowledge base articles (KBAs). API references and other information about this and earlier releases is available on https://docs.silabs.com/.

7.2 Security Information
Secure Vault Integration
This version of the stack is integrated with Secure Vault Key Management. When deployed to Secure Vault High devices, mesh encryption keys are protected using the Secure Vault Key Management functionality. The table below shows the protected keys and their storage protection characteristics.

Key
Network key Application key Device key

Exportability on a node
Exportable
Non-exportable
Non-exportable

Exportability on Provisioner
Exportable

Notes
Derivations of the network key exist only in RAM while network keys are stored on flash
In Provisioner's case, applied to Provisionerr's own device key as well as other devices' keys

Keys that are marked as "Non-Exportable" can be used but cannot be viewed or shared at runtime. Keys that are marked as "Exportable" can be used or shared at runtime but remain encrypted while stored in flash.
