Questions about BLE mesh provisionning/configuration process

[Arij]

Hi,

I have couple of questions about provisionning/configuration process:

1- I'm scanning with my phone and many ble devices show up (my devices and  neighbor devices for e.g), I want my devices to be authenticated with their UUID and show that they belong to my range before any provisioning and configuration happen , is that possible to make?

2- Is it possible to transmit provision/configuration informations about mesh nodes from provisioner to another node on the mesh?

3- When I decide to unplug my DK and stop this node from being in mesh network, is there any notification or information provided  by provisioner about it to other nodes?

Thank you in advance,

Hi Arij, 

1. What exactly did you mean by "they belong to my range" ? Did you mean RSSI  ? The UUID of a node can be found in the advertising packet. If you want to filter that out, you can just modify the app and only show the device with the required UUID. By spec, you can have authentication when provisioning by blinking an LED, displaying a number or NFC for example. In this demo you can find we do blinking to authenticate. 

 

2. Yes, it's possible. But it's not defined in spec, so there is no standard on how to send the data. You define it proprietary. We have the remote provisioning solution which is quite similar, not exactly the same though. 

3. No, but you can use heart beat to see if a node is active or not. The provisioner wouldn't play any role here except for setting the interval of the heart beat. It's upto each node to keep track of other nodes.

Thank you for your valuable response, Now it's clear and yes I meant RSSI for the first question :)

You are welcome. RSSI is already showed in our demo app when you do scanning :)
