LPN nodes run under low power situation without friendship.

Hi support team,

We're planing to implement the scenario like this.  In the mesh network, there are a few LPN nodes (i.e., 10 nodes) and one server node(non-low power node). 

Each LPN node wakes up when the button is pressed and sends a short message to the server. 

I got the info from this page  "It has not entered the low power mode yet, as the friendship is not established."  We don't want to establish the friendship between LPN nodes and the server in our project. so my question:  Is there an available way for these LPN nodes to work under low power mode, but no friendship with the server?

Hi Young!

No, it is not possible to have an LPN without a friendship. All of the LPN's could be friends with the server, though that might take up some space as the server needs to save information about its friends. You could also do something similar to the EnOcean bridge, with all of your nodes simply being beacons.

However, with every node being LPN it doesn't sound like Bluetooth mesh is what you need. For mesh to pay off you would need at least one of the nodes to be connected to the power grid, as relay is the backbone of it. Are all of the nodes within reach of the server? In that case it sounds to me like some BLE beacons and a BLE scanner would be preferable.

Let me know if there is anything else!

Best regards,

Hi Elfving,

Thanks for your info about my question.  Yes, you're right. All of the nodes within the network can reach to the server. 

you mentioned "it sounds to me like some BLE beacons and a BLE scanner would be preferable.". For our scenario, could you give us more sugesstions aoub this?  which examples can we refer to?

Thanks.
