Method and device for transmitting/receiving data using Bluetooth mesh network

1. A method for a first device included in a Bluetooth mesh network to transmit and receive data through the Bluetooth mesh network, the method comprising:

listing addresses of one or more devices or one or more device groups qualified to transmit a message to the first device;

connecting with a second device excluded from the Bluetooth mesh network for setting an address of the first device,

wherein the second device performs a role as a control device to set an address to devices included in the Bluetooth mesh network;

receiving, from the second device, a first message for setting the address of the first device,

wherein the first message includes at least one of an address field including the address or a first response field for whether a response to the first message is requested,

wherein the address field includes at least one of a unicast address as a unique address allocated to the first device or a group address as an address of a group in which the first device is included, and

wherein the first message includes an index for a number of the first device in the group when the address field includes the group address;

setting the address to a source (SRC) characteristic of the first device; and

transmitting, to the second device, a first response message with respect to the message, when the response field represents a response request.

2. The method of claim 1 , wherein the first message is transmitted using a Bluetooth Generic Attributes Profile (GATT) protocol.

3. The method of claim 2 , wherein the step of connecting is performed based on a Bluetooth connection procedure with the second device, when the first message is transmitted using the Bluetooth GATT protocol.

4. The method of claim 3 , wherein the Bluetooth connection procedure includes:

transmitting an advertising message to the second device;

receiving a connection request message from the second device on the basis of the advertising message; and

performing an authentication procedure with the second device.

5. The method of claim 1 , further comprising:

transmitting a control message for controlling at least one device to the at least one device included in the mesh network,

wherein the control message includes at least one of a second response field indicating whether a response to the control message is requested, a source address field indicating an address of a device transmitting the control message, or a destination address field indicating an address of a device for receiving the control message.

6. The method of claim 5 , further comprising:

receiving a second response message from the at least one device, when the second response field indicates that a response is requested.

7. The method of claim 5 , wherein the destination address field includes one of a unicast address indicating a specific device and a group address indicating a group including one or more devices.

8. The method of claim 7 , wherein the control message is transmitted to the one or more devices, when the destination address field includes the group address.

9. The method of claim 1 , further comprising:

transmitting a notification message including status information of the first device to at least one device included in the mesh network.

10. The method of claim 1 , wherein the first message further includes an operation code instructing the first device to set the address.

11. The method of claim 1 , wherein the address is one of a first source device address indicating an address of a device transmitting a message and a destination device address indicating an address of a device receiving a message.

12. The method of claim 11 , further comprising:

receiving a second message including a second source device address indicating an address of a third device from the third device;

comparing the second source device address and the first destination device address, when the address is the first destination device address; and

dropping the second message, when the first destination device address is different from the second source device address.

13. A device, as a first device, for transmitting and receiving data through a Bluetooth mesh network, the device comprising:

a communication unit communicating with an exterior wirelessly or wiredly; and

a processor functionally connected to the communication unit,

wherein the processor is configured to:

list addresses of one or more devices or one or more device groups qualified to transmit a message to the first device;

connect with a second device excluded from the Bluetooth mesh network for setting an address of the first device,

wherein the second device perporms a role as a control device to set an address to devices included in the Bluetooth mesh network;

receive a first message for setting the address of the first device from a second device,

wherein the first message includes at least one of an address field including the address or a first response field indicating whether a response to the first message is requested,

wherein the address field includes at least one of a unicast address as a unique address allocated to the first device or a group address as an address of a group in which the first device is included, and

wherein the first message includes an index for a number of the first device in the group when the address field includes the group address;

set the address to a source (SRC) characteristic of the first device; and

transmit a first response message with respect to the message to the second device, when the response field indicates a response request.

14. The method of claim 1 , further comprising:

dropping one or more messages not transmitted from the addresses.
