The mesh network configuration (JSON schema) is compatible with

• Mesh Configuration Database Profile 1.0.

Bluetooth mesh specifications are available at Bluetooth.com.

Supported features

1. Provisioning with all features available in Mesh Profile 1.0.1, including OOB Public Key and all types of OOB, using GATT bearer.
