Gecko SDK (GSDK) Version 4.2.0.0
WARNING: The Bluetooth mesh SDK is not included in GSDK 4.2.0.0, because this version of the Bluetooth mesh SDK contains material that is not yet released to the public by the Bluetooth SIG.
Current Bluetooth mesh users should not update to this version, as your current Bluetooth mesh SDK will be deleted. If you do install it, you can revert to version 4.1.3 by installing it from the Tags tab.
Alternatively, if you are a Bluetooth SIG member, you can obtain a version based on the upcoming Bluetooth mesh 1.1 specification by raising a Silicon Labs Salesforce ticket with BTMesh as the Software Solution.
