Abstract - We propose and discuss BE-Mesh-Bluetooth low Energy-Meshed network, a new paradigm for BLE BluetoothLow Energy that enables mesh networking among wirelessly interconnected devices, both in a single hop and multi-hop fashion.

We also prototype, as a proof of concept, an open source Android library that implements our communication paradigm and an Android application that allows the exchange of text messages across the mesh network. Last, we demonstrate how BE-Mesh enables Internet access sharing with the whole mesh from a single Internet-connected device.

Wireless mesh networks can handle individual nodes not working and are tolerant to environments such as forests and hills where data may not be able to go directly from one point to another.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This is a wireless mesh with a range of up to 1km between nodes. There are 16 nodes in each mesh, and all nodes use the same frequency. Each node can sample two analog voltages and shares these with the mesh.

The mesh is tolerant of faults with individual nodes, and data takes multiple paths to get to the destination. Nodes can also interface to the internet, and to other meshes that that been set up for a different frequency. Individual nodes may only be able to talk to a few nearby nodes. One problem with building meshes is complexity. This mesh simplifies things by using a synchronised clock, and much of the mesh protocol revolves around getting the clock working. Each node exchanges the time with nearby nodes.

If a node receives time data from a nearby node it notes the number of the node, and the number of the last node it received a time from, and takes the lower of the two. If node zero is in the mesh, then all the nodes ultimately synchronise to node zero's time. If node zero is shut down, then node 1 will take over this function. Nodes flash a led in time with their clock, and within a minute or so, all the nodes will be flashing in synch.

Once this is working, each node transmits only during its allocated time slot. This avoids data clashes and minimises errors. Each node collects its own data and adds a time stamp to this.

When a node transmits, it transmits the data for the entire mesh, including the time stamps. Any node that hears this data looks at the list, looks at its own list, and replaces any old data with newer data.

There are 16 nodes and each node has two analog values, making a total of 32 integer values to share through the mesh.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Works with SoftDevice S v8. This may be used as a basis for your own applications, or you could choose to do it yourself from scratch. In theory, the framework should be compatible with most SoftDevice based projects, but some restrictions to hardware and software modules apply, see Resource allocation for details.

This service may be accessed by external nodes, just as any other GATT service, through a connection established via the SoftDevice. See section GATT service for details about structure and access.

Note that the application controller requires the ble-sdk-arduino framework. This allows you to operate an Arduino along with an nRF51 dev kit in the mesh, making it easier to create mesh applications. Each nRF51 example project has a separate target named "nRF xxAA serial" that incorporates the serial interface with the rest of the project.

The framework is built to be compatible with most existing SDK example projects, and as of v0. Applications which already use this hardware module must be altered to use a different interrupt for mesh processing. A rebroadcasting mesh network works by flooding all messages to all nodes in the network through broadcasts. Each time a device receives a broadcast message from some other device in the mesh, it repeats the message, or rebroadcasts it, letting its neighbors hear the new message.

The neighbors rebroadcast the message to their neighbors, and the process is repeated until all devices in the mesh have received the message. This lets wireless devices talk to each other without being within direct radio range, as devices between them help relaying the messages. All nodes receive all messages that are transmitted within their range, and any node may update the mesh-global states. There is no hierarchy, and no directed data links.

The framework will attempt to allocate as much time as possible, in order to listen for other nodes' messages. All nodes in the mesh share a set of indexed data slots.

The data contained at each index is propagated through the mesh with version numbers, with the objective of synchronizing the same version of the data across all nodes in the mesh. Each time a node overwrites a value, it increments the version number, and all nodes that receive a broadcast message with a version number that is higher than the one in its database, will adapt this new version of the value.

The Trickle algorithm dynamically decides intervals at which a value will be broadcast by a node, based on how many consistent messages the node picks up, and when the last update to the state it manages was.

The Trickle algorithm dynamically adapts to node density and value update frequency. The framework provides each handle-value pair with one Trickle-instance an isolated version of the algorithmand utilizes a Least-recently-used cache- system to store the values. When a value falls out of the "data cache", the device stops retransmitting it, and when the value falls out of the larger "handle cache", the device also forgets which version of the value it saw last.

The application is responsible for advertising and managing the external connection, and the "BLE Gateway example" displays a way to achieve such behavior. Using the framework.
