  Specification Compatibility:
  This release contains an implementation of the Mesh Protocol 1.1, Mesh Model 1.1, Mesh Binary Large Object Transfer, and Mesh Device Firmware Update specifications. These specifications are not yet adopted Bluetooth SIG specifications, and no Bluetooth qualification program currently exists for these specifications. Therefore, these specifications are not approved for use in commercial production. Any experimental use of the features in these specifications are “AS IS”, and no Bluetooth license rights are granted.

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.
• Link-time optimization feature of GCC has been disabled, resulting in a slight increase of image size.

KEY FEATURES

• Support for mesh draft specification 1.1:
• Mesh Protocol
• Mesh Binary Large Object Transfer Model (MBT)
•  Mesh Device Firmware Update Model (DFU)
• Reduced project flash consumption by optimizing Mesh stack code size
• Support added for xGM240P PCB Modules and BG22/BGM220 Explorer Kits
• Support added for GCC version 10.3-2021.10 and IAR version 9.20.4

New Items

New Features

• Added in release 4.2.1.0
• New Hardware:
• Support for EFR32xG21 Rev C and Rev D
• Added in release 4.2.0.0
• The default Bluetooth address used for advertising Mesh data and secure network beacons has been changed to be a private address that is periodically reassigned to a new random value. This is because using a public address would not work well with Mesh 1.1 privacy-enhancing features, Private Network Beacons and Private GATT Proxy.
• Added in release 4.0.0-prev
• Support for Bluetooth mesh over advertising extensions (AE) has been added as a proprietary extension. This feature facilitates faster transmission of long messages, compared to the standard
• Bluetooth Mesh using regular advertisements. For instance, device firmware update using AE can result in greatly reduced transmission times compared to standard operation. Bluetooth Mesh over AE is, however, not compliant with the Bluetooth mesh specification. Products using Mesh over AE are not fully interoperable with products that are strictly compliant with the Bluetooth mesh specification.
• Support for choosing the BLE advertising BGAPI the Bluetooth mesh stack uses internally has been added. Previously, the mesh stack used internally only the old BGAPI, which prevented the use of the  newer BLE advertising BGAPIs in the application, since the old and the new APIs do not work interoperably. Now the BGAPI the stack uses can be specified by component selection in the project.

Example applications:

• IV update is demonstrated through the embedded examples and Bluetooth Mesh – Host Provisioner.
• Key refresh and key export to Network Analyzer is demonstrated with Bluetooth Mesh – Host Provisioner.
• Tooling:
• NCP Commander is now able to create a new mesh Network, provision and configure nodes into that network, and send mesh packets using the Generic Onoff Client and Generic Level Client models.
• This allows testing nodes with Generic Level and Onoff Server models and any other models bound to these.
• New Hardware:
• Support for xGM240 SIP Modules

Added in release 3.0.0-prev
The support for the following have been added based on specifications that are in Validation status and are not available for qualification. In order to obtain Bluetooth SIG qualification, customers will need to upgrade to a release which will be based on the adopted specification, which will be made available after the adoption.

1. Mesh Protocol 1.1 with the following features
   • Remote Provisioning (RPR)
   • Certificate Based Provisioning (CBP)
