摘要： A method of enabling a publisher mesh node (101) to update a number of hops that is to be used for communication between said publisher mesh node (101) and a subscriber mesh node (102) in a wireless mesh network, wherein said method comprises the steps of periodically receiving (103, 104), by said subscriber mesh node (102), broadcasted messages from said publisher mesh node (101), wherein said broadcasted messages comprise a number of hops that said broadcasted messages may traverse in said mesh network, determining, by said subscriber mesh node (102), that one or more periodically broadcasted messages have not been received (105), transmitting, by said subscriber mesh node (102) in reply to said determination that one or more periodically broadcasted messages have not been received, a probe message to said publisher mesh node (101), wherein said probe message comprises a number of hops corresponding to a periodically broadcasted message that was received by said subscriber mesh node (102).

摘要： A method of sharing an established connection between a primary device in a network and one of a plurality of secondary devices. The method comprising the steps of receiving from an unconnected secondary device said plurality of secondary devices, an advertising packet for identifying said unconnected secondary device, sending, to said unconnected secondary device, a connection request based on said received advertising packet for establishing a connection between said unconnected secondary device and said primary device, said connection being shared among said unconnected secondary device and said one of said plurality of secondary devices, and transmitting, to secondary devices sharing an established connection, connection parameters, wherein said connection parameters define a time shared multiplexing scheme thereby facilitating sharing of said established connection. A complementary method and device for performing a method according to the present disclosure are also presented herein.

摘要： Embodiments support routing in a Bluetooth based mesh network (100) between a source node (121) and a destination node (124) via one or more intermediate nodes (122; 123). A first node (121; 122; 123) sends (901; 1001) a message to another, second node (122; 123; 124) of the mesh network (100), which second node (122; 123; 124) is neighbouring the first node (121; 122; 123) in said routing. The message being any one of the following: a unicast message being routed according to said routing, a group-cast message being routed according to said routing, and a route response, "RREP", message sent as part of creating a route for said routing. The first node (122; 123) listens (902; 1002) for a receipt acknowledging response sent by the second node (123; 124) in response to receipt of the sent message.

摘要： An advertising wireless device (110) broadcasts (202; 802) an advertising message over a wireless communication link (115). The advertising wireless device receives (203a; 803), from an advertisement responding device (120-1), a request message that was sent by the advertisement responding device (120-1) at a certain point in time in response to the broadcasted advertising message. Said certain point in time being randomized within a listening time period during which the advertising wireless device (110) listens for a response to the broadcasted advertising message and is able to receive the request message.
