It specifically creates 4 new MGMT commands and 2 new MGMT events: MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of AD Types which will trigger Mesh Packet Received events MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound Mesh packets can be simultaneously queued, and what the currently queued handles are. MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet, with the number of times it should be sent, and the BD Addr to use. Discrete advertisments are added to the ADV Instance list. MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message request. MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh Advertisement packet, along with timing information. MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is no longer queued for delivery.
