Abstract: This application discloses systems, devices, and methods for indoor navigation and tracking with a mesh network. In one aspect, a navigation device includes a receiver configured to receive a locational signal from a node network. The locational signal identifies a respective node of the node network, and the node network is distributed throughout a physical space. The navigation device includes a memory storing a program and a processor in communication with the receiver and configured to execute the program to calculate a position of the navigation device from the identity of the respective node, determine a routing instruction from the position of the navigation device to a destination based on the position of the navigation device and a known mapping of the node network in the physical space, and update the position of the navigation device and the routing instruction as the navigation device moves through the physical space.

Abstract: In accordance with embodiments, methods for the recovery of security credentials of a Bluetooth mesh network are disclosed. A computing device of the Bluetooth mesh network receives user login information, and generates a network key of the Bluetooth mesh network based on the user login information. The computing device generates an application key of a first node to be provisioned based on user login information. A device key is generated using the unicast address of the first node and part of user credentials. The current sequence number is recovered by one of the four techniques depending on the characteristics of the network. The unicast addresses of the nodes are assumed to be sequential and later validated by sending messages. IV index is recovered using processes defined in the Bluetooth mesh standard. After recovery of the above parameters, the mesh network can operate normally using the aforementioned computing device.
