Bluetooth mesh combined with NFC

[HDuc]

Hi all,

I am learning about the combination between Bluetooth mesh and NFC. I would like to realize a simple exercise below.

Assuming that I have a mesh network with 4 elements already provisioned: 1 client (Button) and 3 servers (LED). In normal function, the client connects with all 3 servers. For example, when clicking a button on the client, the LED on all 3 servers are lits. An NFC Tag Reader is attached to the client, and 3 Tag antennas are attached to 3 servers. Every time, one server touches the client, they detect each other through NFC and at that time the client connects only with this server (Ex: When clicking a button on the client, only the LED on this server is lit, the LEDs on 2 others servers have no effect). After that, moving this server away from the Tag Reader of the client, they all return to the normal function the same as in the beginning.

So, I would like to know if I could realize the same procedures as described in BLE Pairing Using NFC. I think it can read the ID address through NFC, but after that, I do not know how to use this address to create a separate connection in the bluetooth mesh network. Or, are there other ways to do that.

Could you help me?
Many thanks in advance.

Hi,

In Mesh you can subscribe to group addresses to send a on/off message to a group of devices. So maybe you can send a group address to add to the subscription list of a device using NFC?

Hi Marjeris,

Thank you for your reply.

I have thought about that idea. But how they can understand the detected NFC field is from the right device and when extending to a multi-nodes mesh network, it may be difficult to choose a good group address.
