4 Detailed function
4.1 The term
Node:
Any device that is or can be part of the ESP-MESH network.
ROOT Node:
The node at the top of the network. The Mesh network has one and only one root node.
Child Node:
If node X is connected to node Y, and X is farther from the root node than Y (the number of connections crossed is
more), then X is called a child node of Y.
Node address:
The MESH network uses MAC address + IP address port. Any node has two MAC addresses: AP and STA.
The MESH network address is the AP MAC address, and the MAC address of the parent node is the AP's MAC
address.
The child node address is the STA MAC address.
The MAC address of the STA is stored in the Mesh routing table;Only the root node has an IP address, and other
nodes have no IP addresses.
MESH ID:
MESH ID is the identification of the Mesh network.
4.2 Tree topology

Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd. 12
4.3 Node type selection
E104-W07 supports three types of nodes: unconnected nodes, root nodes, ordinary nodes, and leaf nodes.
If the module uses the default node type (node   not connected to the network) MESH network is started, the
module automatically enumerates to generate the root node. If the specified module is the root node, the module will give
up automatic enumeration.
The module automatically enumerates the root node, based on the strongest router signal obtained from all nodes,
which is the root node.
In the MESH network, only the root node can access the socket master. Other nodes communicate with the external
network and can use the root node to forward data.
Leaf nodes are only generated during automatic networking. Manually specifying the node type does not support
specifying as a leaf node.
4.4 Mesh networking
The module supports two networking modes: manual networking and automatic networking.
4.4.1 Automatic networking
Automatic networking, without user intervention, automatically enumerate ROOT nodes after the module is
powered on, and automatically select the parent node. The user only needs to communicate after the networking is
completed. Automatic networking can avoid too deep network layers and too complicated routing.
In automatic networking, the node type can only be configured as an idle node.
4.4.2 Manual networking
For manual networking, users can specify the modules as ROOT nodes and ordinary nodes.
Note: Before the MESH network is officially built, it must be ensured that all nodes in the network have the same
configuration. Each node must be configured with the same MESH ID, router configuration, and softAP configuration.
4.5 Networking with and without routers
The so-called router network refers to whether the router is connected according to the node.
The module supports these two networking modes. No routing network does not need to specify the router ssid,
password. But the channel must be specified. If there is a router network, the channel may not be specified. If the
specified channel is different from the routing channel, or the channel is not specified, then the root node needs to scan
the full channel, so that it takes longer to connect to the router; if the correct channel is specified, join the router Time
will be soon.

4.6 MESH data flow
In the MESH grid, only the root node has the TCP/IP protocol stack, which means that only the base node can
connect to the Internet for communication. Only the root node supports TCP, UDP, and MQTT.
In use, ordinary nodes can send data to the root node, and the root node forwards the data to the Internet.
4.7 MQTT
For more MQTT knowledge, please refer to the Chinese website: http://mqtt.p2hp.com/ .
4.7.1 Quality Service Level QoS
QoS 0：Distribute once at most. The performance of the underlying network since the message was distributed. The
recipient can only receive the message once, or not even once.
QoS 1：Distribute at least once. The quality of service in this case ensures that the message reaches the recipient at
least once.
QoS 2：is distributed exactly once. This is the highest quality of service and is used in situations where lost and
duplicate messages are unacceptable. This quality of service will increase overhead.
4.7.2 Quality Service Level QoS
The client and server can store the session state so that they can reliably deliver messages across a series of network
connections. This is used to control the life cycle of the session state.
If CleanSession is set to 0, the server must resume communication with the client according to the current session
state (the client's unique identifier is used as the session identifier). If there is no drawing related to the unique identifier
of the client, the server must create a new session. The client and server must store the session after disconnecting
[MQTT-3.1.2-4]. When the session with CleanSession as 0 is disconnected, the server must also store all QoS1 and QoS2
messages related to the client's subscription as part of the session state [MQTT-3.1.2-5]. You can also choose to store the
QoS0 message.
If CleanSession is set to 1, the client and server must disconnect the previous session and start a new session. The
session exists as long as the network connection exists. The state data of a session must not be reused by subsequent
sessions [MQTT-3.1.2-6].

Inquire
AT+ROUTER?
+ROUTER: ["ssid"],["password"],[routerswitchdisable],["bssid"]
Set up
AT+ROUTER=[“ssid”],[“password”]
,<routerswitchdisable>,<“bssid”>
+OK success
+ERR:[NUM] error
Parameter
ssid
WIFI name. The maximum length of the string is 31 bytes
password
WIFI password. The string length is 8~63 bytes
routerswitchd
isable
0
Enable switching
1 (default)
No switching
-
——
bssid
Router MAC address. Fixed to 6 bytes
Description
1. Restart to take effect, save when power off;
2. The default value is all empty, or 0
3. If the router SSID is hidden, the BSSID must be specified;
4. In the actual application scenario, there are multiple routers/APs with the same SSID. At this time, the
BSSID must be specified, otherwise multiple MESH networks will appear, causing nodes to be unable to
communicate with each other.
5. If the BSSID is specified, but routerswitchdisable is not set, when the router with the specified BSSID is
still not found after several times, the entire network is allowed to switch to another router with the same
SSID. The new router may also be on a different channel.If the passwords of the new switching router and
the previous router are different, a mesh network may be established, but the root node will never connect
to the new switching router, which is a risk
Example
Get the current router settings:
AT+ROUTER?
Module response:
+ROUTER:"test","1357924680",0,"00:00:00:00:00:00"
Set the router name to: test01, the password to: 12345678, and no designated router MAC address:
AT+ROUTER="test01","12345678"
Set the router name as: test02, the password as: 12345678, and the designated router MAC as: 01:02:03:04:05:06;
AT+ROUTER="test02","12345678",0,"01:02:03:04:05:06"
Set the router name: test03, no password, no specified MAC
AT+ROUTER="test02"

Inquire
AT+MEID?
+MEID:["mesh id"]
Set up
AT+ MEID = ["mesh id"]
+OK success
+ERR:[NUM] error
parameter
mesh id
The identity of the Mesh network. It consists of 6 bytes.
XX:XX:XX:XX:XX:XX
Description
1. Restart to take effect, save when power off
2. Default value: "00:00:00:00:00:01"
3. MESH ID is the MESH network identification. Modules with different MESH IDs cannot join the
same network.
Example
Get the mesh ID:
AT+MEID?
Module response:
+MEID: "00:00:00:00:00:01"
AT+MEID=”00:00:00:00:00:22"
