Ble mesh v1.1 direct forwarding feature support

[Nagajans]

I would like to implement ble mesh direct forwarding feature in my code but i am not finding zephyr library for that. Is there any possibility to get link for zephyr direct forwarding feature code or library?

Hi, 

The current implementation does not support Bluetooth Mesh Directed Forwarding (MDF). See Subnet Bridge and Directed Forwarding.

This feature is really important to us to choose BLE mesh over zigbee and thread for our upcoming project. I would like to know when can we expect the support for Bluetooth Mesh Directed Forwarding (MDF) in Zephyr?

Please contact your regional sales manager or use the form of Sales related questions for the request/schedule/roadmap.

I raised query at sales team but i didnt get any reply so far but i wonder how they know software related release dates in zephyr for MDF feature support?

[Lorenzo Amicucci]

can you please elaborate the use case? numeber of nodes, topology, gateway vs no gateway, vendor model vs standard model, payloads, etc?
We see no real impact of MDF in some scenario. MDF provides an edge only in some specific use cases.

Thanks

We are a leading manufacturer of EC fans integrated into energy-efficient HVAC systems. In cleanroom environments, we may deploy up to 1,000 EC fans connected via a mesh topology with a central gateway. Our implementation currently uses a vendor-specific model with a maximum payload of 80 bytes, with potential plans to scale up to 256 bytes. We believe that the MDF (Mesh Directed Forwarding) feature will significantly help in reducing network traffic in such high-density deployments.
