I have an existing phone app (using the traditional GATT system), and I would like mesh-enable my products so that if the products can see each other, then the phone can connect to and control any node (so, not so much an automation system but a relay system for configuration messages).
1. Is there a good tutorial on how the mesh-proxy connection works in the firmware/phone side (does the proxy "broadcast" all the BLE Node addresses so it's truly transparent, or should I put in a GATT attribute for "I really want to connect with this node?" or?
... I understand how the pieces are relayed over-the-air, but I'm not sure how to configure the stack and the phone app.
2. Can I pre-share the Network Security Key for a "all nodes are part of the mesh out of the box"? I don't expect the factories that our sensors are in to be close to each other (and if they are, cutting nodes out would be just as easy as commissioning them in...
