The Bluetooth Mesh standard actually is based on a Bluetooth 4.0 feature set (basic advertising and scanning), so really any BLE device can support it. The problem is that the software is complicated, so typically only newer devices have software support.
Many chip vendors have BT mesh implementations, including Nordic, TI, SiLabs, Cypress, Dialog, and ST.
