In some implementations, an infrared signal can be sent to the bluetooth MESH device by an external stand-alone device as an infrared signal emitting source (external infrared device); the Bluetooth MESH equipment can be in the original Bluetooth MESH network, namely the working state can be at least an accessed state, and the Bluetooth MESH equipment can also have different working states, such as a relay state and a low power consumption state, according to different roles in the original Bluetooth MESH network; the broadcast state may be referred to herein as a beacon signal broadcast state (beacon), a bluetooth MESH Device in the broadcast state may be a PB-ADV-enabled, initialized, unconfigured Device in an unconfigured state and not in any configuring process, the Device may broadcast an unconfigured beacon signal (upnp Device beacon), a data frame of the beacon signal may generally include a beacon type, a Device UUID (universal Unique Identifier), an OOB (Out of Band) information, and a URI (Uniform Resource Identifier) hash code, and the beacon signal may be scanned by a configurator (e.g., a bluetooth MESH Device Provisioner serving as a configuration node, a node in a bluetooth MESH network, i.e., a bluetooth MESH Device in at least an accessed network state) to be reconfigured.
For example, the infrared receiving unit on the bluetooth MESH device may be a switch triggered by an external infrared signal, and when the infrared signal is kept received, the switch may be kept open or closed to drive and operate the reset terminal of the bluetooth MESH device, and after the operation timing is reached, the bluetooth part of the bluetooth MESH device enters a configurable state or an initialized state (for example, deleting a network configuration file that is stored). Further, for better security, the infrared signal may be a modulated data signal, and demodulating the infrared signal may include conventional processes such as decoding and decryption, and demodulated data of the infrared signal may be obtained after demodulation; the infrared signal interaction between the bluetooth MESH device and the external infrared device may be implemented by establishing a session and transmitting infrared protocol data (e.g., necoprotocol) in the session, and the infrared data frame may include a bootstrap code, a device code, a data code, a cyclic delay, and the like.

For the passive mode, after receiving the infrared signal in real time, performing a judgment (or verification), where the judgment is to determine whether the bluetooth device address of the bluetooth MESH device is consistent with the bluetooth device address in the demodulated data of the infrared signal, and when the judgment is consistent, performing switching of the working state of the bluetooth MESH device to a broadcast state, where any one bluetooth device address at least has a MAC address (Media Access control address). For the response mode, after handshaking with the external infrared device is successful (session establishment is completed), the external infrared device may encrypt and send information such as bluetooth device address in the session, specifically: sending an infrared feedback signal through the Bluetooth MESH equipment, wherein the Bluetooth MESH equipment is also provided with an infrared transmitting unit; receiving an infrared signal responding to the infrared feedback signal through the infrared receiving unit (the infrared signal can have information such as encrypted Bluetooth equipment address and control signaling conforming to an infrared communication protocol, and the control signaling can be used for triggering switching or resetting); and judging whether the Bluetooth equipment address of the Bluetooth MESH equipment is consistent with the Bluetooth equipment address in the demodulation data of the re-received infrared signal, if so, starting the step of switching the working state of the Bluetooth MESH equipment to the broadcasting state, and if not, returning to the step of receiving the infrared signal through the infrared receiving unit of the Bluetooth MESH equipment.

The infrared signal can be directly directed to one or more Bluetooth MESH devices to be reset; the infrared signal can also point to one or more Bluetooth MESH devices which do not need to be reset, and the demodulated data of the infrared signal is forwarded or relayed to one or more Bluetooth MESH devices which need to be reset by the Bluetooth MESH devices which receive the infrared signal, wherein the infrared signal can be forwarded by an infrared receiving and transmitting unit on each Bluetooth MESH device, and the demodulated data of the infrared signal can also be relayed or forwarded by the Bluetooth MESH devices in the Bluetooth MESH network through the MESH network.
For the infrared signal, there may be one infrared signal, or there may be multiple infrared signals simultaneously or multiple infrared signals sequentially, the infrared signal may be directly directed to one or more bluetooth MESH devices in the original bluetooth MESH network, and according to the difference in working state and the number of bluetooth MESH devices receiving the infrared signal, there may be one or more switching operations (or reset operations, which enable the bluetooth MESH device serving as a node in the original bluetooth MESH network to be removed from the original bluetooth MESH network): switching an accessed node state of the Bluetooth MESH equipment in the original Bluetooth MESH network to a broadcast state, switching a relay node state of the Bluetooth MESH equipment in the original Bluetooth MESH network to the broadcast state, and switching a low-power consumption node state of the Bluetooth MESH equipment in the original Bluetooth MESH network to the broadcast state. The Bluetooth MESH device can be used for non-contact connection configuration in a line of sight, has less pre-configuration requirements on the Bluetooth MESH device, and is simple to implement and low in cost.
As shown in fig. 3, each bluetooth MESH device in the bluetooth MESH network has an infrared transceiver unit IR, and a node ABCDEFHG (continuous letters indicate a plurality of nodes, and a node AB indicates a node a and a node B) is a general node (a single circle of a solid line circle), and the general node may be connected to the bluetooth MESH network through a broadcast bearer layer (ADVbearer) and/or connected to the bluetooth MESH network through a broadcast bearer layer after being relayed, such as a 100-type connection (short dashed double arrow, broadcast mode, non-relay type) and a 101-type connection (solid double arrow, broadcast mode, relay type); node QRS is a relay node (double-circle solid line circle), node IJKLM is a low-power consumption node (single-circle dotted short dashed line circle), node PO is a friend node of the low-power consumption node (double-circle outer thick inner thin solid line circle), node N is a node (single-circle dotted line circle) supporting establishment of a friend connection relation but not having an established friend relation, if node Q is connected through 101 type to provide relay for node ABCDERP, node O is connected through 102 type (long-segment dotted line double arrow) to provide response of polling for node LM, and general node T does not support establishment of a broadcast bearer layer, but can be connected to a bluetooth MESH network through node S through a GATT bearer layer (GATT bearer), if 103 type connection (double-solid line double arrow) is used; if the node K is in the passive infrared communication mode and the node HT is in the response infrared communication mode, the operator 104 may perform infrared communication handshake with the node HT through the external infrared device EID by means of 105-type connection (three solid lines and two arrows), the operator 104 may transmit 106 (single solid line and one arrow) infrared signals to the node K through the external infrared device EID in a unidirectional manner, after verification is completed, the node KHT may be removed from the bluetooth MESH network, and then a redistribution network operation is performed, a network role of the node KHT accessed to the bluetooth MESH network again may change, for example, the node K may no longer have a friendship relationship with the node P, the node K may also no longer be a low-power-consumption node, and the node K may be connected to the bluetooth MESH network through a broadcast bearer layer via a relay of the node P.
For the infrared signal, there may be one infrared signal, or there may be multiple infrared signals simultaneously or sequentially, the infrared signal may point to one or more bluetooth MESH devices in the relay node state in the original bluetooth MESH network, and the demodulated data of the infrared signal is forwarded to the bluetooth MESH device in the relayed node state by the bluetooth MESH device in the relay node state; and switching the accessed node state of the Bluetooth MESH equipment in the state of the relayed node to a broadcast state through the demodulated data. Because the infrared signal is a straight line sight distance transmission signal, the safety is realized, and the Bluetooth MESH equipment which is out of the infrared signal reachable range of the external infrared equipment can be switched and the distribution network operation can be performed by combining the relay node. Here, the method can be used for performing in-line-of-sight and non-in-line-of-sight contactless connection configuration, and the configurable range can extend to the whole coverage range of the bluetooth MESH network.
For forwarding demodulated data, the bluetooth MESH device in the relay node state may first determine whether the demodulated data includes the own bluetooth device address and the bluetooth device address of the general node relayed by itself or the node transmitting data through the GATT bearer layer (both nodes may be in the accessed node state or the relayed state), and if only includes the bluetooth device address of the general node relayed by itself or the node transmitting data through the GATT bearer layer, select to forward the demodulated data, and may send an infrared signal having the demodulated data to the bluetooth MESH device in the accessed node state through the infrared transceiver unit of the bluetooth MESH device in the relay node state, thereby completing the state switching of the bluetooth MESH device at the target node. In addition, the method can also be carried out by a mode of transmitting Bluetooth signals, in this case, the relayed accessed node is not required to be provided with an infrared transmitting and receiving unit, the bluetooth signal with the demodulated data can be transmitted to the bluetooth MESH device in the accessed node state by the bluetooth transceiving unit of the bluetooth MESH device in the relay node state, the bluetooth signal may comprise an acknowledgement message, in particular a confignode Reset, for resetting a node and removing the node from the accessed Bluetooth MESH network, the reset Bluetooth MESH device can feed back a status message responding to the confirmation message to the Bluetooth MESH device in the state of the relay node, since the bluetooth MESH device in the relay node state has communicated with the external infrared device, the infrared receiving and sending unit can be further configured to feed back the status message to the external infrared device; the demodulated data of the infrared signal can be a trigger action to trigger the bluetooth MESH device to send out a defined bluetooth signal, so as to realize a simple conversion, or can be effective data in the infrared signal or plaintext data demodulated (including decoding, decryption and other processes), and the plaintext data is modulated into a bluetooth signal by the control unit, so as to realize a conversion.
As for the infrared signal, there may be one infrared signal, or there may be a plurality of infrared signals simultaneously or in sequence, the infrared signal may point to one or more bluetooth MESH devices in the friendly node state in the original bluetooth MESH network, and poll the friendly bluetooth MESH devices through the bluetooth MESH devices in the low power consumption node state in the original bluetooth MESH network; responding the demodulated data of the infrared signal to the Bluetooth MESH equipment in the low-power-consumption node state through the friend Bluetooth MESH equipment; and switching the low-power consumption node state of the Bluetooth MESH equipment in the low-power consumption node state to a broadcast state through the demodulation data. Here, the method can be used for performing in-line-of-sight and non-in-line-of-sight contactless connection configuration, and the configurable range can extend to the whole coverage range of the bluetooth MESH network.
For completing the switching by demodulating data, the bluetooth MESH device in the Friend node state may first determine whether the demodulated data includes the own bluetooth device address and the bluetooth device address of the low power consumption node which is the Friend node, if only the bluetooth device address of the low power consumption node corresponding to the Friend node is included, and after a certain time, the bluetooth MESH device in the low power consumption node state has already performed polling (Friend Poll), then select to forward the demodulated data (the polled data may be used as a trigger condition, and a message in response to the polling may be unrelated to an infrared signal), and may send an infrared signal with the demodulated data to the bluetooth MESH device in the low power consumption node state through the infrared transceiver unit of the bluetooth MESH device in the Friend node state, thereby completing the state switching of the bluetooth MESH device at the target node, wherein, the bluetooth device address may be an address in a bluetooth MESH network. In addition, the method can also be carried out by a mode of transmitting Bluetooth signals, in this case, an infrared receiving and transmitting unit of the low-power consumption node is not required, the bluetooth signal may be used to respond to polling of the low power node, the bluetooth signal with the demodulated data may be issued to the bluetooth MESH device in the low power node state by the bluetooth transceiving unit of the bluetooth MESH device in the friend node state, the bluetooth signal may comprise an acknowledgement message, in particular a confignode Reset, for resetting a node and removing the node from the accessed bluetooth MESH network, the reset bluetooth MESH device may feed back a status message in response to the acknowledge message to the bluetooth MESH device in the state of the friend node, since the bluetooth MESH device in the friend node state has communicated with the external infrared device, the infrared transceiver unit may be further configured to feed back the status message to an external infrared device.
As shown in fig. 4, it can be defined as in fig. 3, the external infrared device EID of the operator 200 is located outside the line-of-sight range of the node LMGT at this time, the external infrared device EID of the operator 200 can perform infrared communication with the node OS, if a network reconfiguration operation is to be performed on the node L, first, the external infrared device EID of the operator 200 can send data to the node O through a 105-type connection, after polling of the node L, the node O can forward the data to the node L through the 105-type connection or forward the data to the node L through a 102-type connection, for example, a bluetooth MESH device corresponding to the node G cannot establish a normal 101-type connection with the node O due to being in a free state, and may be disconnected from the bluetooth MESH network, at this time, the external infrared device EID of the operator 200 can send data to the node O through the 105-type connection, the node O determines that the node G address exists, optionally, the state of the node G is additionally verified through a bluetooth heartbeat data packet, if the normal feedback of the node G is successfully obtained, after the node O replies to the external infrared device EID, the operation and maintenance person 200 may determine whether to perform the reset, and the node O may not reply, and when the node O does not successfully receive the heartbeat after time out, the node O may directly send an infrared signal to the node G, so that the node G is reset, and the switching operation is completed.
For the bluetooth MESH devices in the bluetooth MESH network, each bluetooth MESH device may be respectively provided with an infrared transceiving unit, at least one bluetooth MESH device may be provided with an infrared transceiving unit, or some bluetooth MESH devices may be provided with infrared transceiving units; for the target bluetooth MESH network, the bluetooth MESH devices performing connection configuration relative to the original bluetooth MESH network are the same bluetooth MESH network, that is, the bluetooth MESH devices needing connection configuration belong to the bluetooth MESH network access configuration again, and the method and the device can be applied to a scene that the bluetooth MESH devices need to be initialized and configured again in a non-contact manner when the bluetooth MESH devices are in the abnormal state free network connection state.
In some scenes, only one bluetooth MESH device in one bluetooth MESH network is provided with an infrared receiving and transmitting unit, infrared communication is carried out between the bluetooth MESH device and external infrared devices, infrared communication data are transmitted in the bluetooth MESH network through bluetooth communication, and the configurable range can be expanded; in some other scenarios, an internal infrared device for processing infrared communication data may be independently arranged within the coverage of the bluetooth MESH network, and a control unit of the internal infrared device may perform any wireless protocol data interaction with a control unit of any bluetooth MESH device in the bluetooth MESH network, but the internal infrared device does not belong to the bluetooth MESH network.
As shown in fig. 5, the definitions of fig. 3 can be extended, each bluetooth MESH device in the bluetooth MESH network can be located within the line of sight (mutual light reachable) of the internal infrared device, because in reality, when performing peer-to-peer infrared communication, the network address and the installation position of the bluetooth MESH device may need to be known, the internal infrared device IID can record the address information and the installation position of the bluetooth MESH device on each node, and then the operation and maintenance person 300 needs to reset any node in the bluetooth MESH network and only needs to perform infrared communication with the internal infrared device IID through the external infrared device EID, thereby realizing convenient and fast non-contact bluetooth MESH device switching and distribution network operation.
The connection configuration between the Bluetooth MESH equipment and the target Bluetooth MESH network is executed, the Bluetooth MESH equipment works depending on the Bluetooth MESH network, and the step of accessing the Bluetooth MESH network is roughly divided into: broadcast (beacon), invite (Invitation), exchange Keys (Exchanging Public Keys), Authentication (Authentication), Distribution of the Provisioning Data, etc. For example, a configurator node (Provisioner) scans whether a beacon signal broadcasting device UUID and OOB information exists, if the beacon signal has OOB information, the OOB information is acquired, the configurator node performs invite and function selection operations through PDU, if the OOB information does not exist, the configurator node directly jumps to the invite and function selection operations, then judges whether a public key in the OOB information is used, if the public key is used, starts to exchange the public key, and performs ECDH (Elliptic Curve Diffie-Hellman key exchange, which is an anonymous key consensus protocol) calculation, if the public key is not used, the ECDH calculation is directly performed, then authentication interaction is performed according to a selected public key authentication method, and after authentication (if the public key is used), the configurator node can acquire PDU containing configuration data including encrypted and authenticated network key, Index, identification, PDU integrity check value, etc.
The infrared signal is a linear line-of-sight transmission signal, can shield a far-end stealing signal in an indoor environment, has certain safety characteristic, and after the infrared signal enters a broadcasting state, the configuration of the Bluetooth MESH equipment depends on a Bluetooth MESH protocol, so that the safety is ensured;
the embodiment of the invention provides a scheme without using physical contact operation, can carry out distribution network operation in a severe environment which cannot contact Bluetooth MESH equipment and under a scene which is inconvenient to contact, is more convenient for the connection configuration of the equipment, and is compatible with a Bluetooth MESH connection technology, while the existing Bluetooth MESH equipment needs to be in contact operation to switch the connection state.
