3. Basic Operation
3.1 Hardware design
It is recommended to use DC steady voltage power supply to supply power to this module, the ripple coefficient of
power supply is as small as possible, the module needs reliable grounding;
Note the proper connection of the power supply positive and negative poles. Reconnecting may result in permanent
damage to the module.
Check the power supply to ensure that permanent damage to the module occurs between recommended supply
voltages, if exceeded;
Please check the stability of the power supply. The voltage cannot fluctuate significantly and frequently.
Please check the stability of the power supply. The voltage cannot fluctuate significantly and frequently.
When designing power supply circuits for modules, it is often recommended to keep more than 30 percent of the
spare, which is advantageous for the whole machine to work steadily over a long period of time.

Modules should be kept as far away as possible from large parts of electromagnetic interference such as power
supply, transformers, high frequency walkers, etc.
High frequency digital, high frequency analogue and power lines must be avoided under the module. If we have to
go under the module, suppose that the module is welded to Top Layer and copper laid on the contact part of the
module (all copper laid and well grounded), we must go near the module digital part and follow the wire on Botom
Layer.
Assuming that modules are welded or placed in Top Layers, random paths in Botom Layers or other layers are also
wrong, affecting the stray and reception sensitivity of modules to varying degrees;
Assuming that there is a large amount of electromagnetic interference around the module, the performance of the
module can be greatly affected. According to the intensity of the interference, it is recommended to stay away from
the module.
Assuming that there are large electromagnetic interference lines around the module (high frequency digital, high
frequency analog, power supply) can also greatly affect the module's performance.
Keep away from the 2.4 GHz TTL protocol in some physical layers, e.g. USB 3.0;
The module must not be mounted inside the metal housing, which will greatly weaken the transmission distance.

1.As shown in the picture,the module can only connect the VCC,GND,TX and RX to perform the communication test.
2.PWM1, PWM2, PWM3 corresponding to SIGMESH HSL model;
3.DIO1 (PA0 boot corresponding to TLSR8253) and DIO2 (PA1 boot corresponding to TLSR8253) are switch volume
input guides that customers can access to and use according to their own needs.
4.The low power module can wake up via DI01, DIO2 and serial port after going to sleep.
4. Functional Introduction
The MESH network architecture is shown below
The biggest advantage of this module is that it can relay any data in the network. Any module can be relayed and
received at the same time. The module's data signal coverage is about 50 meters. The following is a functional schematic.

Interpreting the simulation application scene above:
The distance from Module A to Module C is 70 meters, beyond 50 meters of our module's transmission distance, so
module A cannot send data directly to module C. If a module B is placed between module A and module C, the data will
be relayed by B and then received by module C.
Module A needs to send data to the whole thing.The network, modules B, C, D, E need to receive data from A, then
module A will send the data at the broadcast address(0XFFFF).
If module A needs to specify data issuance, All you need to do is write the address of module E at the address in the data
format (see instruction format for details). But module E is 140 meters away from module A and cannot communicate the
data directly, but as long as these modules are on the same network, the data will be there.The following link reaches
module E, where A sends data to B, B to C, C to D, D to E
4.1 Basic Concept
4.1.1 NetKey
Network keys are used to protect network-layer communications.is a key generated by using a random number generator
that meets the core specifications.(See Mesh Profile 3.86)

Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd.
11
4.1.2 AppKey
Application keys are used to protect the keys of the upper transport layer.Generated using a compatible random
number generator. Application Key Identifier (AID) is used to identify application keys.(See Mesh Profile 3.86)
4.1.3 Device Role
The SIG MESH protocols have roles that are Node, Low Power Node, Relay Node, Friend Node, Proxy
Node.Related functions are described as follows:
Node: Edge node in the entire Mesh network that has the ability to receive and transmit data but does not have the
ability to relay
Low Power Node: Low power nodes that do not have to keep sending or listening to packets on broadcast channels
because of the presence of Friend Node. Just check if there is any data on Friend Node.
Relay Node: The core node of the network layer that extends network coverage. After receiving packets sent by other
nodes, determine whether forwarding is required based on the determination conditions of the network protocol.
Friend Node: Low power Node can set up a friendly connection with low power Node as a proxy node for low power
Node. When data from low power Node is reached, it can be cached waiting for low power Node to query and obtain.
Proxy Node: Proxy node that receives information through a load layer (broadcast load or GATT load) and resends
the message through another broadcast load or GATT load.It plays a key role in the non-Mesh low power Bluetooth
device becoming a member of Bluetooth Mesh network. The basic purpose of proxy node is to perform load layer
conversion.It enables the transition from broadcast load layer to GATT load layer, and vice versa.Therefore, devices that
do not support broadcasting can send and receive Bluetooth Mesh messages via a GATT connection.E104-BT12SPN
supports proxy node function and enables Mesh network control with mobile phone-side APP (the data compression
package contains APP-related SDKs for customer development).
A single device supports only one role. In the EBYTE scheme, our modules support three roles: provision node and
mesh node, LPN node, which is the device responsible for networking.
Four ways to connect SIG_mesh:
1. ADV (Not Relayed): Connection not capable of broadcasting.This applies when two nodes send and receive
messages to and from each other, but without relay capability, packets cannot be forwarded.
2. ADV (Lower Power): Low-power broadcast connection.Used to send and receive packets between low power
Node and Friend Node. On this connection, low power Node initiates a request to establish a connection to Friendship
and to query from Friend Node whether there is a packet of its own.

3. ADV Bearer: Broadcast forwarding connection.The two nodes can forward and forward broadcast messages
based on broadcasts, and can act as relay.Our product works on this connection.
4. GATT Bearer: Used for nodes that can participate in MESH networks without ADVbearer capabilities, sending
and receiving proxy PDUs over GATT connections via proxy protocol with other nodes.
The types of devices that our company supports are provision and mesh, lPN.
Provision node: A special Node node that initiates the entire network.Also called Gateway.It adds unstructured devices to
the Mesh network.The Provision node provides provision data to the unallocated device, including netkey, appkey, and
the unicast address corresponding to each of the devices' elements.
Mesh Node: Our Mesh node is a combination of four characters: Node, Relay Node, Friend Node and Proxy
Node.convenient and quick to use.
4.1.3.1 Moule
There are many models in SIG MESH. Our E104-BT10 module has three addresses. Each one can be bound to more
than one model. HSL's model has three addresses because it needs to control three things: brightness, saturation, and
color temperature.

4.1.3.2 Unicast,Element
An address corresponds to an element from the Model introduction above. We can call it an elemental address. It is
the unique address assigned to a Node node by a PROVISION device during a PROVISION process. Each Node device
in the same Mesh network may have multiple addresses.E104-BT12USP is a Provision device and E104-BT12NSP is a
Node device.

4.2.2 SIG Messages
The E104-BT12 module supports SIG Generic and Lighting HSL model control (see Mesh Profile and Mesh Model
introduction for relevant SIG message definitions).The SIG message format is as follows:
Send
Order（1byte）
Target address (2 bytes)
Sig mesh message
0xC1
Primary address of Target
device
Request
Receive
Order（1byte）
Target address (2 bytes)
Original address (2
bytes)
Sig mesh message
0x41
Primary address of Target
device
Source device master
address
Respond
For example: 1.Generic onoff control of Generic model:
Control the device whose main address is 0004, output
high level without delay
Request
09 C1 0004 8202 01000000
Respond
08 41 0004 0001 8204 01
Control the device whose main address is 0004, output low
level without delay
Request
09 C1 0004 8202 00000000
Respond
08 41 0004 0001 8204 00
2. Transparent transmission of information
E104-BT12 supports transparent transmission of user data. The maximum length of the serial port sub-packet is 60 bytes
(the maximum payload of a single packet in the bottom layer of the mesh is 8 bytes, and data larger than 8 bytes will be
automatically sub-packed and sent, due to the efficiency of the entire mesh network during the sub-packet sending
process. Not high, it is recommended to limit the data sent in a single time to less than 8 bytes), the data format is as
follows:
Send
Order（1byte）
Target address (2 bytes)
Data
0xC2
Primary address of Target
device
Valid data
Receive
Order（1byte）
Target address (2 bytes)
Original address (2
bytes)
Data
0x42
Primary address of Target
device
Source device master
address
Valid data
For example: Device 0001 sends the hexadecimal data of "00112233445566778899" to device 0004
