Each virtual addres Bluetooth mesh networking implements a publish/subscribe message-oriented communication system. 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. - + ### Provisioning Provisioning is the process by which a Bluetooth device (unprovisioned device) joins the mesh network and becomes a Bluetooth mesh node. This process is controlled by a provisioner. A provisioner and the unprovisioned device follow a fixed procedure as defined in the Bluetooth Mesh Profile [4]. A provisioner is typically a smartphone running a provisioning application. For a more in-depth look at different aspects of provisioning see links number 13. ## Demo -For this demo we are trying too understand the basics behind bluetooth mesh( picture below). - +For this demo we are trying to understand the basics behind bluetooth mesh (picture below). + + ### Difficulties + There were three difficulties for this demo: making the dongle work, making Bluetooth work on the dongle, and lastly debugging with RTT. The main problem was making the dongle work. After accidentally removing the bootloader in the dongle, it wasn't working properly.
