Bluetooth Mesh Heartbeat Subscription

[isundaylee]

When setting up Heartbeat Subscription for a node, a single unicast address is specified as the source. Does this mean that a node can only subscribe to heartbeat messages from a single other node? If so, is there a way for a single node to monitor the state/health of all other nodes in the mesh network? Thanks!

Hi,

Yes, a node can subscribe to heartbeat messages only from a single node.

If you want to monitor state/health of all other nodes in the mesh, you should use periodic health model status messages (current status/ fault status).
