Overview of SmartMesh
current and even heavily-burdened routing nodes, handling traffic from
dozens of neighbors, typically consume less than 200�A – over one hundred
times less than other mesh networking solutions.
for monitoring network health, providing alerts when network reliability is
at risk, which include when a node has a weak radio link or only a single link
back to the rest of the network.
where needed and wireless connectivity, routing redundancy and frequency
agility is handled by the network – no specialized RF skills or site surveys
Why does BLE mesh make sense to IoT and the Networked Society?
Short-range radio devices in a capillary network, such as BLE devices, can be connected to the Internet by a capillary gateway.Nevertheless, the short transmission range for such devices with a single-hop network topology prevents the use cases of IoT applications from running over a large number of devices.BLE mesh enables these use cases by providing peer-to-peer and robust multi-hop connectivity for a large number of local BLE devices.This way, IoT application data can be exchanged between any local BLE device and the Internet through the mesh network and a gateway.

What is the Bluetooth SmartMesh?
The Bluetooth SmartMesh is a communication protocol designed by CSR’s Robin Heydon, published in Summer 2013.CSR makes Bluetooth chips and the goal was to enable Bluetooth for home automation.Bluetooth typically relies on a point to point connection.which requires good signal strength.It is also difficult to communicate with many devices simultaneously.
Bluetooth Smart Mesh — why does it make sense for IoT?
Also known as Bluetooth Low Energy, Bluetooth Smart is an interesting short-range radio technology that could be used for connecting tiny devices into the Internet of Things.

How does the SmartMesh work?
As stated, the SmartMesh is just a communication protocol, which only relies on broadcast transmissions and listening for messages.It is very generic and does not require a Bluetooth radio as the transport layer.We call the transport the bearer.
What is BLE mesh?
In general, a wireless mesh network is a network built on a number of fixed and mobile nodes that provide a robust and multi-hop communication for peer-to-peer transmissions.There are some challenges in transforming a single-hop BLE network into a mesh.Take the topology as an example: most off-the-shelf BLE chipsets have Bluetooth version 4.0-compliant firmware implementation.However, version 4.0 inherently has a topology limitation towards peer-to-peer mesh networks: the supported topology called “Piconet” is a master-slave connection network that does not allow multi-hop communications.Since version 4.1, BLE topology introduced “Scatternet” which enables a master node of one or several slave nodes to simultaneously be a slave of another node.The Scatternet absolutely makes the multi-hop connection possible.Yet, it does not inherently change the Piconet-based asymmetric topology model, where a relay node can receive/relay a message in data channels only after establishing a master-slave connection with a corresponding transmitter/receiver.This challenge calls for innovative solutions to overcome these constraints.
Why BLE mesh?
Bluetooth Smart has some constraints when it comes to the network coverage, the transmission range and peer-to-peer communications, which all limit the use cases BLE is suited for.
