Such an approach ensures that different types of products can coexist in a mesh network without being affected by messages from devices they do not need to listen to. The act of sending a message is known as publishing. Based on the configuration, the mesh nodes select messages sent to specific addresses for processing. This technique is known as subscribing. A publisher node sends messages to those nodes that have subscribed to the publisher. Typically, mesh messages are addressed to group or virtual addresses. For example, look at figure 4. -![Figure 4](img/publish_subscribe.png) +![Publish and subscribe](img/publish_subscribe.png) ### Provisioning @@ -111,7 +111,7 @@ Provisioning is the process by which a Bluetooth device (unprovisioned device) j For this demo we are trying to understand the basics behind bluetooth mesh (picture below). -![Figure 5](img/demo.png) +![Demo set-up](img/demo.png) ### Difficulties @@ -121,13 +121,13 @@ After accidentally removing the bootloader in the dongle, it wasn't working prop To make example `nrf/samples/bluetooth/mesh/light` or `switch` work with the dongle a change is needed in the `.conf` file. -![Figure 6](img/bluetooth_dongle_problem.png) +![Dongle configuration](img/bluetooth_dongle_problem.png) After removing these two lines from the .conf file it will work exactly as you’d expect.
