RE: Negotiating which device will act as provisioner

Hi Michael,

Bluetooth Mesh doesn't have a concept of flexible provisioners. There isn't a defined way on how to promote a device to be provisioner or when to switch role, etc.

What we would suggest is to have a button on the device that you can switch to ON to enable provisioner role on the device. If having a physical button could be a problem, you can think of using BLE (a phone) to set the command to the device.

Ideally it's the phone who should be the provisioner, however it's not supported for now. You would need to define proprietary GATT protocol on the phone to do provisioning via a node. I have an example of GATT+Mesh here (no provisioning though).

Do what you proposed also possible, but it won't guarantee that a device wouldn't accidentally enter provisioner mode if there is interference or range that blocks the provisioning beacons and then we end up having 2 or more independent provisioners (meaning 2 or more different networks).
