Is it possible to parallelize mesh node provisioning?

Is it possible to parallelize mesh node provisioning?

[Jiaquan He]

Hi All,

I’m working on a bluetooth mesh node provisioner based on BlueZ 5.54, and expecting to provision a bunch of devices (mesh nodes).

I’m just simply calling org.bluez.mesh.Management1.AddNode multiple times, but it seems that we can have only one prov-initiator at a time.

So is there any way to have multiple provisioning sessions at the same time? Or does it make sense to provision multiple nodes at the same time?

Thank you.

Regards,
Jiaquan

I’d just like to echo Inga’s discouragements regarding the security risks of Bulk un-manned “Just Works” style provisioning, but also to add that no, multiple provisioning “sessions” are not currently supported, and I do not see them as something we plan on supporting.
