Provision Bluetooth Mesh Nodes at Factory

[WestCoastDaz]

Is it possible to provision Bluetooth Mesh nodes at the factory so they automatically join an existing network?  Our application is more industrial in nature and we don't want users to be required to use a Smart Phone to add nodes to the network.

I found this article put it's not completely clear https://devzone.nordicsemi.com/f/nordic-q-a/35393/automatic-meshing/135980#135980

Thanks in advance.

Hi Darren, 

Yes it's possible. But it's not recommended by Bluetooth spec to do "hardcoded" provisioning. Also you need to make sure all device key are generated randomly, avoid using one golden key for all devices. 

But I don't see any technical issue of doing that. Our current implementation all network information are stored in flash. You just need to flash that information when in production. Make sure you customized the data for each node. And you have a database of the nodes on the provisioner.
