What do you mean by a Mesh beacon ? A beacon like eddystone/ibeacon or something else ?
Edit: If you are making a relay device used for Mesh, this would typically need to be a mains powered device like an LED light. A battery operated mesh device would need to be a GATT proxy.
We do not have reference designs for AC powered devices.
Are you looking for an AC powered relay device or something different ?
Edit:
The beacons/tags in the asset tracking use case can be battery powered. The relay devices if they are battery powered may need to limit their scan time which will impact the time needed to discover a beacon. Bluetooth Mesh v1.0 relay node is not very battery friendly, but you can consider the Fruity Mesh and evaluate the power needed for a relay node.
i am working on asset tracking with Mesh ... I want to spread out Relay devices and when some beacon passes the nearest Relay should capture the data and broadcast. The relay device may operate on 2 AA batteries
