In today’s tutorial: We’ll first take a step back and talk a little bit about interoperability and compatibility in Bluetooth mesh. Then, we’ll go through a demo of setting up a mesh network that includes a mix of off-the-shelf devices. Finally, we’ll go through the source code step-by-step and the changes needed to implement the functionality for this demo. Compatibility and Interoperability The power of having a standard like Bluetooth mesh that a certified device must comply to is: The ability to add devices from different manufacturers to any mesh network. The ability within the network for devices to interact with…
Now that we’ve covered the basics of Bluetooth mesh and also gone over how to run a simple example on the nRF52 platform, it’s time for us to dig deeper into the source code of each type of device/node involved in a mesh network. If you missed the previous posts in this series, you can find them all here: Bluetooth mesh tutorial (part 1): covering the basics as well as some of the different terminologies such as Nodes, Elements, States, Properties, Messages, Addresses, Publish/Subscribe, and Managed Flooding. Bluetooth mesh tutorial (part 2): covering terminologies such as Models, Scenes, Relay nodes, Proxy nodes, Friend nodes, Low power nodes, and the architecture of Bluetooth mesh.…
In the last post in this series on Bluetooth mesh (found here), we provided a high-level overview of the nRF5 SDK for Bluetooth mesh. We also listed the different examples provided as part of the Nordic SDK. The most complete of these examples is the lighting example, and this is the one we’ll go forward with demoing and explaining. In this week’s post, we’ll go over building and running this example and understanding the different parts within it. In the upcoming posts, we’ll get into the details of the source code for each device. Here’s a diagram showing the network…
