How to use Subnet in Mesh

[rbagree]

I am looking for resources/documentations about implementing subnets in Mesh. The use-case I want to implement is:

1. Create two subnets: Subnet A and Subnet B.

2. Provision a node X (Let's say a temperature sensing node) which has network key of both Subnet A and Subnet B.

3. As a starting point Let's say Node X is connected to Subnet A and publish the temperature reading in Subnet A (using the Subnet A's network key)

4. I move the Node X from Subnet A to Subnet B. The Node X should be able to attach itself with Subnet B and start publishing the temperature reading using the Subnet B's network key.

Can someone point me to the relevant resources to implement the above use-case.

Let me try to rephrase my doubt: 
1. I have two subnets ( which implies I have 2 models ad 2 appkeys and 2 netkeys ...All this is fine and understood)
2. I have provisioned my temperature broadcasting node and have supply both the net keys during configuration.
3. I installed the node in room 1 (Subnet 1) and it is broadcasting its temperature reading using model 1 (bind to Subnet 1)
4. Now I only physically move the node from room 1 (subnet 1) to room 2(subnet 2). So how would the node understand that it has to broadcast using model 2 (bind to subnet 2) as the subnet 1 is not available?

In other words how would the node switch the model on its own?

Imp: The node is not subscribed to any topic. It is just broadcasting its temperature reading.

Hi Ravi, 

Thanks for the explanation. Now I understand what you want to do.  In your case, if you don't have a button to physically tell the node that it's being moved from room 1 to room 2, you would need to implement two client models on your node to send  acknowledgement messages to get response from other nodes in each subnet. Based on the RSSI on the response of other nodes, you detect that you are in room 1 or room 2.

It worked. Thank you for all your time and effort.

I'm happy to help :)  Glad that it worked.
