Friend node
：
The low power node can establish a friendly connection with the friend node. As the proxy node of the low power
node, when the data of the low power node is reached, it can be cached in the Friend node, waiting for the low power node to query
and obtain.
Proxy node:
A proxy node that accepts information through a bearer layer (broadcast bearer layer or GATT bearer layer) and
resends the message through another broadcast bearer layer or GATT bearer layer. It plays a key role in the process of non-mesh
low-power Bluetooth devices becoming members of the Bluetooth mesh network. The fundamental purpose of the proxy node is to
perform bearer layer conversion. It enables conversion from the broadcast bearer layer to the GATT bearer layer and vice versa.
Therefore, devices that do not support the broadcast bearer layer can send and receive various Bluetooth mesh messages through the
GATT connection. The E104-BT10N-IPX supports the proxy node function, and the mobile terminal APP can implement mesh
network control (the data compression package includes the APP related SDK for the customer to develop).
A single device supports only one role. In EBYTE solution, our module supports two roles: the provisioning node and the mesh
node. The provisioning node is the device responsible for networking. The mesh node is the repeater node that sends and receives data
and forwards data.
There are four connection methods in SIG_mesh
：
1
、
ADV
（
Not Relayed
）
:That is, there is no connection with the relay capability. This situation applies to the fact that two
nodes send and receive messages to each other, but without relay capability, data packets cannot be forwarded.
2
、
ADV
（
Lower power
）：
That is, a low-power broadcast connection. Used to send and receive data packets between the low
power node and the friend node. On this connection, the low power node will initiate a request to establish a connection with the
friendship, and query the friend node for its own data packet.
3
、
ADV Bearer
：
Broadcast forwarding connection. The broadcast message can be sent and received between the two nodes
based on the broadcast forwarding, and can be forwarded as a relay. (Our products work on this connection)
4
、
GATT Bearer
：
For nodes without ADVbearer capability, they can also participate in the MESH network, and send and
receive proxy PDUs on the GATT connection with other nodes through the proxy protocol.
Devices supported include provision and mesh.
Provision node
：
It is a special node and is the initiator of the entire network. Also known as gateway. It adds unnetworked
devices to the mesh network. The Provision node provides provision data to the unprovisioned device, including netkey, appkey, and
the unicast address corresponding to each element of the device.
Mesh nodes
：
plays role of node
、
relay node
、
friend node
、
proxy node. It is very convenient.
4.1.4 Model
There are many models in SIG MESH. There are three element addresses in the module. Each address can
be bound to multiple models. Each row in the table below is a model. The HSL model is specially bound with
three addresses for in the HSL model, you need to control the brightness, saturation, and color temperature.
