Bluetooth mesh routing with subnets

A method for handling a broadcast data packet using a network () including a plurality of nodes (NH, N, N, N, N, N, N), the method including: receiving, at a sending node, the broadcast data packet; checking, at the sending node, whether the broadcast data packet has been received at the sending node on a previous occasion, wherein if the sending node has not previously received the broadcast data packet the sending node enters a broadcast delivery mode, the broadcast delivery mode including: switching to a scan mode to listen for advertisements from other nodes in the network; starting a timer; wherein upon receipt of an advertisement from a neighbouring node the sending node sends an instance of the broadcast data packet to the neighbouring node and resets the timer.

Broadcast delivery techniques in a wireless network

A method and system for communicating with wireless messaging enabled door locks. The method includes advertising availability of the door lock via wireless messaging for a first period of time; triggering a message send event; determining a destination node; connecting to the destination node; sending the message to the destination node; and entering a low power state for a second period of time, wherein the second period of time is longer than the first period of time; wherein the destination node is chosen from a second door lock or a computing system.

Mesh networking using peer to peer messages for a hospitality entity

A method for data transfer includes establishing a first wireless connection between a transceiver and a handheld device, the transceiver initially operating in an peripheral role and the handheld device operating in a central role; switching a role of both the transceiver and the handheld device in response to establishing the first wireless connection, the transceiver module switching from the peripheral role to the central role, and the handheld device from the central role to the peripheral role; and establishing a second wireless connection between the transceiver and the handheld device subsequent to the switching.

Bluetooth&#x2122; low energy data transfer communication system and method

A method of operating an access control system including a plurality of access controls each operating as a node including: receiving a node information from one or more nodes of the access control system, the one or more nodes including an origination node and a destination node; determining one or more routes between the origination node and the destination node in response to the node information or a minimum hop distance between the originating node and the head node and a minimum hop distance between any intermediate routing node and the head node; receiving a reroute message indicating a failed node between the destination node and the origination node; and determining an alternate path from the origination node to the destination node around the failed node in response to the one or more routes.

Robust multipath routing methods in wireless network

A method for communicating data between Bluetooth Low Energy (BLE) devices () in a network () comprising multiple nodes, the method comprising: broadcasting data from a broadcasting node (); receiving the data at multiple receiving nodes (); transmitting an acknowledgement (ACK) packet from each of the receiving nodes () to the broadcasting node (), wherein each receiving node () waits for a waiting period before transmitting the ACK packet, and wherein the waiting period is a varying length of time for each receiving node ().

Method and system for broadcasting data in wireless network

A method and system for communicating with wireless messaging enabled door locks is disclosed. The method includes advertising availability of the door lock via wireless messaging for a first period of time; triggering a message send event; determining a destination node; connecting to the destination node via Bluetooth; sending the message to the destination node; and entering a low power state for a second period of time, wherein the second period of time is longer than the first period of time; wherein the destination node is chosen from a second door lock or a computing system.

A method for communicating data between Bluetooth Low Energy (BLE) devices in a network () including multiple nodes (). The method includes starting a scan mode at a first node () having data to send; and determining whether data to send has been transmitted to the first node from an upstream node or a downstream node. If the data to send was received from a downstream node, the first node begins a scan mode. If the data to send was received from an upstream node, the first node begins an ADV event.
