The mesh stack consists of a number of subsystems that are interfaced through a set of API modules. The API modules hide the complexity of their subsystems. The functionality provided in the API is sufficient to make a functioning mesh device, so that there is no need to bypass the API.
The mesh stack's structure is based off the structure of the Bluetooth Mesh Specification and follows the same naming conventions. See Basic Bluetooth Mesh concepts for an introduction to the Bluetooth Mesh.
網格體系結構
網格堆棧由許多子系統組成，這些子系統通過一組API模塊進行交互。API模塊隱藏了它們的子系統的復雜性。API中提供的功能足以創建一個功能正常的網格設備，因此不需要繞過API。
網格堆棧的結構是基於藍牙網格規范的結構，遵循相同的命名約定。關於藍牙網格的介紹，請參閱基本的藍牙網格概念。
- Models: The Bluetooth Mesh models present and implement device behavior.
- Access: The Bluetooth Mesh access layer organizes models and communication.
- DSM: The Device State Manager stores addresses and encryption keys for usage in the models.
- Core: The Core Bluetooth Mesh layer takes care of encryption and message relaying.
- Provisioning: The Bluetooth Mesh provisioning protocol is used for adding devices to the network.
- Bearer: The Bearer layer takes care of low-level radio operation.
- DFU: The Device Firmware Upgrade module cooperates with a bootloader to enable firmware upgrades through the mesh.
- Node Config (not pictured): The node configuration is a utility module that manages the configuration and setup of the device.
- Serial (not pictured): Application-level serialization of the Mesh API allows the mesh to be controlled by a separate host device.
