1GENERAL INFORMATION ON MESH NETWORKS
Mesh networks
A mesh network is a network topology (wired or wireless) in which all hosts are connected “peer-to-peer” without a
centralized hierarchy, thus creating a net-type structure. With this architecture, every node can send, receive, and relay
data. This eliminates the presence of “backbone” points that can isolate parts of the network in case of malfunction. If
a host stops working, data simply takes another route to its destination. A mesh network can relay data via “flooding”
(broadcasting data so that it is received by all nodes within direct wireless range). It can also use predefined routes, in
which case the network must plan for uninterrupted connections or alternative routes.
Wirepas Mesh
The Wirepas Mesh protocol is a wireless network protocol that uses a multi-jump, self-organizing, and decentralized
design. Decentralized network topology enables extremely dense network deployment.
Wirepas focuses on providing a connectivity solution that is highly reliable, optimized, scalable, and easy to deploy.
This solution was specifically designed to meet two major challenges facing wireless mesh networks: network reliability
regardless of its size and density; and low energy consumption by router devices in the network.
Information about Wirepas Mesh technology is available here:

GATEWAY ELA Innovation MESH Gateway
The mesh sensor network comprises two different types of devices: sensor tags and one or more gateways. Each
element may be added to an existing network. Adding new devices to an existing network is made easier with automatic
connection and integration into the mesh network. Once connected, each element in the network can send its sensor
information to a gateway. Mesh connectivity between tags, and message forwarding, are handled automatically and
dynamically.
SENSOR TAG
A sensor tag is a tag in the BLUE PUCK MESH product line equipped with a sensor that periodically transmits its sensor
data to an MQTT broker. Connection between tags and the relaying of sensor information to the gateway is handled
automatically and dynamically in the Wirepas Mesh network.
GATEWAY
A software gateway links the BLUE Mesh tag network to the server. The gateway receives a stream of data sent by tags
and forwards it to an MQTT broker. The received data is then processed by an application to display and/or further
process sensor data.

4.2 OPERATING MODE
Sensor Tag in Autorole mode
The Sensor Tag is configured in a mode referred to as “Autorole”. This mode enables all tags in the network to manage
themselves. Each tag can send its sensor data over the network, and each tag can relay information flowing across the
network. Management is dynamic and automatic. The only constraint is for the tag to be at an acceptable connection
distance to one or more neighboring tags.
The gateway receives network data and transmits it to one or more back-end servers.
The example below shows the connection between tags, gateway(s), and back-end(s).
There are two ways to retrieve data:
•Connect to the Wirepas API and retrieve the data stream respecting the format required by Wirepas.
•Develop your own API and handle message collection yourself.
Sensor data must be retrieved from the various topics presented in the table on the next page.
Messages are received in a generic format described in Wirepas documentation and encoded in protocol buffer format:
https://developers.google.com/protocol-buffers.
Complete information related to message reception and encoding is provided in the following section of the Wirepas
GitHub:
https://github.com/wirepas/backend-apis/tree/master/gateway_to_backend
Sensor Data and MQTT topics
Data is sent by the gateway to a specific MQTT broker the server. The list of topics corresponding to the various sensors
in the BLUE MESH product line are provided in the following table.

Command field details:
[Class]: This parameter enables you to differentiate and address tag groups.
Sent commands are addressed to one or more Classes. It is important to know the tag class when sending commands.
[Type]: The type identifies the chosen functionality or parameter to modify.
* see complete list on next page
[Length]: Data size (length).
[Value]: Value to be updated or activation / deactivation data.
* If “Length” is greater than 1, the value must be written with the least significant byte first.

Information and good practices
•The class indicated in the following tables is provided as an example. You must enter the class corresponding to
your tags when sending commands. Possible values are from 0xF9 to 0xFF.
•The identifier 0x00FA1221 indicated in the following tables is provided as an example. You must enter the
identifier for your tag for an individual command addressed to a tag. For a general command addressed to all
tags, simply replace the identifier with 0x00000000.
•When [Value] is larger than 1 byte, bytes must be in order with the least significant byte first (little endian).
•A sent command is persistent in the network. Each tag in the network receives this command, and each new tag
entering the network also receives the command.
•A broadcast or unicast “ON” command to activate the LED and/or buzzer, either continuous or timed, must be
followed by an “OFF” deactivation command of the same type to cancel that same command.
•If a tag is configured for “TAG NRLS” Long-life Mobile Beacon, it will receive the command and apply it upon
wakeup. Its maximum standby time is equal to the configured data transmission period.
•No information is returned by tags in the network to know whether the command was properly received. You must
calculate and wait the necessary time to be sure that all your tags receive the command.
