Virtually all of us use Bluetooth. Headphones, speakers, beacons, hands-free devices, mice, laptops, tablets, smartphones, and hundreds of other similarly empowered devices. Bluetooth (BT) is also widely used in industry, smart cities, and building automation.
BT transceivers form wireless nodes for sensors and devices to be controlled. Most of those wireless links are either point-to-point or in a star network topology. Such connections work fine in small networks, but they have limitations if numerous nodes are needed. Those larger applications are often better served with a mesh network, a topology that wasn’t available to BT until recently. Now it’s possible to create large networks with BT.
