Queries about Bluetooth Mesh

[CPC]

Hi there,

I am new to the Bluetooth mesh and I am learning about it. I have some questions about Bluetooth mesh. I hope you will help me with this.

Please pardon me, if the questions are basic.

1. What is the significance of virtual address?

2. What is the significance of IV index?

3. In which layer we can define that the message is acknowledged or unacknowledged?

Thanks in advance.
