Zephyr + nRF5 SDK for Mesh v3.1.0

[bwasim]

I've been going through the nRF Mesh SDK and want to integrate it with my Zephyr project.. Reading through the various blog posts and documentation, it seems that the Mesh SDK can only work with the nRF Soft Device, and so I won't be able to use it with Zephyr.. Is this correct ? Are there any future plans to integrate it with Zephyr RTOS ? 

I basically want to use the DFU part to update the firmware on the Mesh and my firmware is Zephyr based.. If I can't use this, what other alternatives are possible ?

Hi,

The nRF Mesh SDK is made to work with our Nordic Softdevice(s) so it's not compatible to be used with Zephyr. It's correct that the future plan is to have our mesh SDK integrated to the NCS SDK (which uses Zephyr) however I don't have a clear date on when it would be available (at least not in the next 3-4 months)

If you need Zephyr and mesh, you can have a look at the mesh implementation in Zephyr. We don't have much experience with this stack unfortunately.

Hi,

any news now about the integration of DFU into Zephyr?

OTA on mesh network is a fundamental feature for the production environment.

thank you

Hi Serra, 
Mesh DFU is still not supported in the implementation in NCS/Zephyr. 
Please be noted that you still can do normal BLE DFU on each mesh node, but it need to be done on each individual node. 

We hope a mesh DFU protocol will be included in the future Bluetooth Mesh specification release. This would help propelling the implementation and compatibility of DFU mesh.

Hi, for my project I switched to SDK Mesh 5, here is supported, right?

Is possible to port the proprietary protocol to NCS/Zephyr?

thank you

Yes, Mesh DFU is supported in nRF SDK for Mesh. 
I think it's possible to port the proprietary mesh DFU in this SDK to NCS/Zephyr. But there will be quite a lot of modification needed and we haven't tried that so I can't say for sure if it would work 100%.
