There is also another bearer, used by the devices that cannot send and = receive advertising packets in controlled way, like mobile phones. This = bearer uses GATT connection to the mesh node that offers a service = called GATT Proxy. Such a node is able to receive mesh messages tunneled = over GATT connection and forward it to the mesh network using ADV = bearer. I'm not a BlueZ specialist but from what I can see, it supports just the = GATT bearer. So you can use it to talk to "real" mesh nodes, but not = really to be such a node.
