Concurrent Bluetooth Mesh and Bluetooth LE
All Bluetooth Mesh SoCs can run both Bluetooth Low Energy and Bluetooth Mesh concurrently. The radio time is time sliced and shared between the protocols. The scheduling is autonomous and connections are maintained. Leverage the interoperability of our Bluetooth LE stack and let a Bluetooth LE device, such as a smartphone, bridge into the Bluetooth Mesh network. The smartphone can then provision/commission in new nodes and interact with the mesh network.
