[−][src]Crate bluetooth_mesh

Pure Rust Bluetooth Mesh Stack.

The layers are designed so they can be put together in different ways to make different stacks (single-threaded, multi-threaded, multi-radio, etc). General stack glue is available in stack while a prebuilt full-stack requires std, async, etc.

How a Bluetooth Mesh Stack works

Modules

access	Access Layer between Models and the rest of the stack (Transport, Network, etc). The most surface layer of the stack.
address	Bluetooth Mesh Addresses. All address are 16-bit except for Virtual Addresses. Virtual Address are 128-bit UUIDs but only a 16-bit hash of the UUID is sent with message.
advertisement
beacon	Bluetooth Mesh Beacon Layer. Currently only supports `SecureNetworkBeacon`s and `UnprovisionedDeviceBeacon`s.
bearer	Bluetooth Mesh Bearers.
bytes
control	Bluetooth Mesh Control Layer.
crypto	Crypto functions (AES, ECDH) that the Mesh uses. AES is primarily used in the `crypto::k_funcs` and in network/application layer encryption. ECDH is used for the provisioning key exchange.
device_state	Device State Manager used to storing device state and having an config client control it.
foundation	Foundation Layer. Handles Publication, Config, etc.
friend	Optional Bluetooth Mesh Friends feature.
interface	Network Input/Output Interface and Filter.
lower	Lower Transport Layer. Primarily handles 4 types of PDUs.
mesh	Common Bluetooth Mesh Objects/Structures.
models
net	Bluetooth Mesh Network Layer is BIG Endian
properties	Bluetooth Properties (From GATT).
provisioning	Provisioning Layer for Bluetooth Mesh Provisioning is Big Endian.
random	Random Number generation for the Mesh. Generalized over the rand Library so there's no hard dependencies.
reassembler	Transport Layer Reassembler.
relay	Optional Relay Feature
replay	Replay Cache based on a BTreeMap that keeps track of each ivi and seq per src address. Updating the IVIndex causes a 'Garbage Collection' like effect that will delete any cache entries for any 'too' old IVIndices.
segmenter
stack	Bluetooth Mesh Stack that connects all the layers together. See ['StackInternals'] for more.
timestamp	Timestamp module for keeping track of time. Different systems have different clock sources so this module generalizes over it. By default, it uses the `std::time::Instant` but it could use a crystal oscillator clock (for ARM) or some other source.
upper	Upper Transport Layer. Primarily focusing on segmentation and reassembly.
uuid	Universally Unique Identifiers or UUIDs.
