Dear BLE mesh Experts,
We want to provision and operate a mesh network using an app that is running on various phones. The idea is to use a single phone during installation/provisioning. Once everything is set up, there will be multiple phones used at the same time to operate the mesh.
While playing around with a few nRF52840 dongles and the Nordic nRF Mesh app, I've noticed that the mesh is only accessible on the phone that provisioned it. A second phone was unable to see the mesh. What data needs to be copied from the provisioning phone over to another phone to enable the second phone to see and operate the mesh? Is it sufficient to just copy the Public, App and Net Keys? Is there anything else that needs to be shared between the phones?
How about the device keys? Do they also need to be shared between all phones? If the device keys aren't shared, would it still be possible for phone B to unprovision a node that was provisioned by phone A?
About proxy nodes:
We want the whole BT Mesh network and all its nodes to be invisible to any passerbys. There are no plans to ever enable any proxy nodes because they would reveal the mesh/nodes. There are also no plans to allow communication with the mesh through BT GATT. Considering this, it should be safe to remove the proxy model from the firmware. Do you have any objections? Are there any common use cases that depend on the availability of the proxy model?
About Android/iOS:
Is it possible to connect to two (or more) BT Meshes at the same time using Nordics IOS/Android-nRF-Mesh-Library? In other words: Would it technically be feasible to split one huge mesh network into various smaller meshes and connect to all of them at the same time? (assuming they are all in range.)
This whole BT Mesh topic is very new to me, so your advice is very much appreciated.
Thank you,
Michael.
