Abstract

The present invention relates to a method and device for setting the role of a device in a Bluetooth mesh network. According to the present invention, a method and device are provided which: receive a write request message including settings information for setting the role of a first device from a control device; transmit a response message as a response to the write request; transmit an advertising message including role information set by the settings information to a second device; and transmit a first message including first information on the first device to the second device.

First claim

1 . A method for setting a role of a first device in a mesh network of Bluetooth, the method being performed by the first device and comprising:
receiving a write request message including setting information for setting the role of the first device from a control device; transmitting a response message in response to the write request; transmitting an advertising message including role information set based on the setting information to a second device; and transmitting a first message including first information related to the first device to the second device.

2 . The method of claim 1 , wherein if the second device performs a relay function, the first information includes first routing information for updating a routing table.

3 . The method of claim 2 , wherein the first routing information includes destination information of a message and device information indicating a next device transmitting the message according to the destination information.

4 . The method of claim 2 , further comprising:
transmitting a request message to request second information related to the second device to the second device; and receiving a second message including the second information in response to the request message, wherein the second information includes an ID indicating the second device.

5 . The method of claim 4 , wherein the second information includes second routing information for configuring a routing table.

6 . The method of claim 5 , wherein the second routing information includes destination information of a message and device information indicating a next device transmitting the message according to the destination information.

7 . The method of claim 1 , wherein if the second device does not perform a relay function, the first information is control information for controlling the first device.

8 . The method of claim 7 , further comprising steps of:
receiving a second message including second information related to the second device from the second device; and transmitting a response message in response to the second message, wherein the second information includes an ID indicating the second device.

9 . The method of claim 8 , further comprising:
transmitting the second message to at least one surrounding device.

10 . The method of claim 7 , further comprising:
receiving a request message to request network information related to the mesh network from the second device; and transmitting a response message including the network information in response to the request message, wherein the network information includes at least one of routing information related to a routing table of the second device or a network ID indicating the mesh network.

11 . The method of claim 1 , further comprising steps of:
receiving a read request message to request role information of the first device from the control device; and transmitting a response message including the role information in response to the read request message.

12 . A first device for setting a role of a device in a mesh network, the first device comprising:
a communication unit for communicating with an outside in a wired or wireless; and a processor functionally connected to the communication unit, wherein the processor is configured to: receiving a write request message including setting information for setting the role of the first device from a control device; transmitting a response message in response to the write request; transmitting an advertising message including role information set based on the setting information to a second device; and transmitting a first message including first information related to the first device to the second device.
