Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that, the communication method of the present application is executed by a gateway device in a bluetooth Mesh network, and meanwhile, any one of the relay device and the bluetooth device needs to join a local area network through the gateway device, where the local area network may specifically be a piconet, and the piconet is a network topology established between the bluetooth devices.
The Bluetooth device related to this application is specifically Bluetooth Low Energy (BLE) device.
Referring to fig. 1, fig. 1 is a schematic flow chart diagram of an embodiment of a communication method of the present application, where the method includes:
s110: and receiving the broadcast message which is forwarded by at least one relay device in the local area network and is sent by the Bluetooth device.
Specifically, after monitoring the broadcast message sent by the bluetooth device, the relay device in the local area network sends the monitored broadcast message to the gateway device. Generally speaking, in view of the characteristics of the bluetooth Mesh network, all relay devices in the local area network can listen to the broadcast message sent by the bluetooth device.
The relay device may be some devices that are usually powered on in the local area network.
In an application scenario, after receiving a broadcast message, a relay device determines whether a bluetooth low energy device sending the broadcast message is a device in a local area network (which may be determined according to an MAC address of the bluetooth device), if not, the relay device directly ignores the broadcast message, if so, the relay device forwards the broadcast message to a gateway device, and after receiving the broadcast message, the gateway device performs step S120.
In another application scenario, after receiving the broadcast message, the relay device directly forwards the broadcast message to the gateway device, that is, the relay device only performs a relay function at this time, and then the gateway device determines whether the bluetooth device sending the broadcast message is a device in the lan, if not, the gateway device directly ignores the broadcast message, and if so, the relay device performs step S120.
S120: the broadcast message is parsed.
Specifically, after parsing the broadcast message, the gateway device obtains the type of the broadcast message, where the type of the broadcast message at least includes a message to be replied and a message that does not need to be replied.
When the broadcast message is a reply-free message, the gateway does not perform any processing, namely for the Bluetooth device, no reply packet is received any more subsequently, so that for the Bluetooth device, the Bluetooth device can sleep immediately after sending the broadcast message, thereby reducing power consumption.
When the broadcast message is a message to be replied, step S130 is executed.
S130: and when the broadcast message is a message to be replied, determining the relay equipment corresponding to the Bluetooth equipment in the local area network.
Specifically, in the multiple relay devices in the local area network, not all the relay devices correspond to the bluetooth device that sends the broadcast message, and therefore when the broadcast message is a message to be replied, the relay device corresponding to the bluetooth device is determined, where one or multiple relay devices corresponding to the bluetooth device may be used.
S140: and sending the reply message to the corresponding relay equipment so as to forward the reply message to the Bluetooth equipment by using the corresponding relay equipment.
Specifically, after determining the relay device corresponding to the bluetooth device, the gateway device only sends the reply message to the corresponding relay device, and then the relay device that receives the reply message forwards the reply message to the bluetooth device.
That is to say, when the gateway device replies, it is not necessary for all the relay devices to forward the reply message, and only the relay device corresponding to the bluetooth device is needed.
As shown in fig. 2, in the existing bluetooth Mesh network, data transmission and reception cannot be performed between bluetooth devices, and power consumption is increased due to overhead (the relay device needs to perform data transmission and reception with the bluetooth devices according to a certain period) in the Mesh protocol; in addition, in an actual bluetooth product, an IOT soc scheme module is often used, which is low in cost and high in integration level, but because the chip resource is limited, one relay device can only support a limited number of bluetooth devices (the bluetooth device can only establish fragnship with the relay device to realize data transceiving), and networking cannot be realized when the maximum connection number of the bluetooth device is exceeded, so that in some scenes, the bluetooth device cannot find the relay device and is continuously offline, and meanwhile, the bluetooth device regularly finds the relay device, which also increases power consumption.
By the method of the embodiment, the connection relationship between the relay device and the bluetooth device is specified by the gateway device, so that the relay device and the bluetooth device do not need to maintain the connection relationship all the time, that is, the relay device and the bluetooth device do not need to receive and transmit data according to a certain period, the power consumption of the local area network can be reduced, and the number of the bluetooth devices establishing the connection relationship with the relay device can be unlimited under the specification of the gateway device.
In an application scenario, the message to be replied includes a real-time reply message (that is, the message to be replied needs to be replied immediately) and a delayed reply message (that is, the message to be replied may be replied after being delayed), and the step S140 of sending the reply message to the corresponding relay device specifically includes: if the broadcast message is a real-time reply message, immediately sending the reply message to the corresponding relay equipment; and if the broadcast message is a delayed reply message, acquiring appointed time carried by the broadcast message, and sending the reply message to the corresponding relay equipment when the appointed time is reached.
Specifically, referring to fig. 3, fig. 3 is a frame format of a broadcast message sent by a bluetooth device according to this embodiment, where a Response type field indicates whether the broadcast message is a reply-free message or a real-time reply message or a delayed reply message in a message to be replied, for example, when data written in the Response type field is 01, the broadcast message is a real-time reply message, when the written data is 02, the broadcast message is a delayed reply message, and when the written data is 03, the broadcast message is a reply-free message; meanwhile, the ReceiveDelay field represents the carried appointed time, wherein the appointed time can be a specific time point, and the time point can be a time point for sending the reply message by the gateway device, or the appointed time can also be a duration, and the duration can be a duration from sending the broadcast message by the bluetooth device to receiving the reply message.
It can be understood that, when the appointed time in the ReceiveDelay is one time, if the broadcast message is a reply-free message or a real-time reply message, the appointed time in the ReceiveDelay is equal to zero, and if the broadcast message is a delayed reply message, the appointed time in the ReceiveDelay is greater than zero.
The gateway equipment analyzes the broadcast message after receiving the broadcast message, immediately sends the reply message to the corresponding relay equipment when reading the Response type field in the broadcast message to represent that the broadcast message is a real-time reply message, acquires the appointed time in the ReceiveDelay field when reading the Response type field in the broadcast message to represent that the broadcast message is a delayed reply message, and then sends the reply message to the corresponding relay equipment after the appointed time is reached.
Different from the application scenario, in another application scenario, after the gateway device resolves that the broadcast message is a delayed reply message and further obtains the appointed time carried by the broadcast message, the gateway device immediately sends the reply message and the appointed time I to the corresponding relay device, and then the relay device sends the reply message to the bluetooth device again when the appointed time is reached.
In the two application scenarios, the appointed time is selected for data transceiving, so that data packet loss can be reduced, and the Bluetooth device can immediately enter a dormant state after sending the broadcast message which is the delay reply message, and then awaken after reaching the appointed time, so that the power consumption of the Bluetooth device can be reduced.
In an application scenario, the step of sending the reply message to the corresponding relay device in step S140 specifically includes: acquiring an appointed channel carried by a broadcast message; and sending the reply message and the appointed channel I to the corresponding relay equipment so as to forward the reply message to the Bluetooth equipment on the appointed channel by using the corresponding relay equipment.
Specifically, with continuing to refer to fig. 3, a ReceiveChannel field in the broadcast message represents an agreed channel, when the gateway device parses the broadcast message, if the broadcast message is a message to be replied, the gateway device acquires the agreed channel in the ReceiveChannel field, then sends the reply message and the agreed channel to the corresponding relay device, and the subsequent relay device sends the reply message to the bluetooth device on the agreed channel, where the agreed channel may be one of channels 37, 38, and 39.
In the application scenario, an appointed channel is selected for data transceiving, and data packet loss can be reduced.
It should be noted that, when the broadcast message does not carry the agreed channel, and when the relay device sends the reply message to the bluetooth device, the reply may be performed on all three channels 37, 38, and 39, or one channel may be arbitrarily selected from among the three channels 37, 38, and 39 for reply.
In an application scenario, the step S130 of determining a relay device corresponding to the bluetooth device in the local area network includes: acquiring the received signal strength of the broadcast message received by at least one relay device in step S110; and searching for the relay equipment with the maximum received signal strength in at least one relay equipment, and determining the relay equipment with the maximum received signal strength as the relay equipment corresponding to the Bluetooth equipment.
Specifically, the relay device corresponding to the maximum received signal strength (rssi) specification of the received broadcast message is closest to the bluetooth device that sent the broadcast message, so that the relay device having the maximum received signal strength of the received broadcast message is determined to be the relay device corresponding to the bluetooth device, and it can be ensured that the subsequent relay device can smoothly and quickly send the reply message to the bluetooth device.
That is, at this time, one relay device corresponding to the bluetooth device is present in step S130.
In another application scenario, in order to save the time for determining the relay device corresponding to the bluetooth device, the step S130 of determining the relay device corresponding to the bluetooth device in the local area network includes: and searching the relay equipment corresponding to the Bluetooth equipment in the local area network in a binding list which is preserved in advance.
Specifically, a binding list is pre-stored in the gateway device, and after receiving the broadcast message in step S110, the relay device corresponding to the bluetooth device that sends the broadcast message is directly searched in the binding list.
In one application scenario, there is only one relay device corresponding to a corresponding bluetooth device in the binding list. That is, at this time, one relay device corresponding to the bluetooth device is present in step S130.
The binding relationship between the relay device and the bluetooth device may be recorded in the binding list by recording the binding relationship between the MAC address and the MAC address, which may be specifically referred to in table 1 below.
Table 1 binding list
As can be seen from the above binding list, there is only one relay device corresponding to the corresponding bluetooth device, and for the relay device, there may be one or more bluetooth devices corresponding to it.
In an application scenario, the establishment mode of the binding list comprises the following steps:
(a) when the Bluetooth device joins the local area network, the broadcast message which is forwarded by all the relay devices in the local area network and is sent by the Bluetooth device is received.
(b) And searching for the relay equipment with the maximum received signal strength for receiving the broadcast message in all the relay equipment.
(c) And establishing a binding relationship between the relay equipment with the maximum received signal strength and the Bluetooth equipment, and storing the binding relationship in a binding list.
Specifically, when the gateway device finds a new device, it is determined whether the new device is an unpaired bluetooth device or a relay device that is not networked, if so, the new device is added into the lan, and after the addition is successful, the gateway device notifies all relay devices and MAC addresses of all bluetooth devices to all relay devices.
Meanwhile, if the equipment added into the local area network is Bluetooth equipment, the Bluetooth equipment also can send a broadcast message, the broadcast message can be monitored by all the relay equipment in the local area network, then all the relay equipment can forward the received broadcast message to the gateway equipment, then the gateway equipment searches the relay equipment with the maximum received signal intensity in all the relay equipment, the searched relay equipment is the relay equipment closest to the newly added Bluetooth equipment, and then the binding relationship between the relay equipment and the newly added Bluetooth equipment is established in the binding list.
Considering that the relative position between the relay device and the bluetooth device may change, that is, for the same bluetooth device, the relay device closest to the same bluetooth device may not be the same as the relay device over time, the binding relationship of the binding list also needs to be updated, and therefore in an application scenario, after step S130, the method further includes: in step S110, the relay node searches for the relay device with the highest received signal strength that receives the broadcast message, and then updates the relay device corresponding to the bluetooth device in the binding list to the relay device with the highest received signal strength.
That is, after determining a relay device corresponding to the bluetooth device according to the saved binding list at step S130, the binding list is updated for determining a corresponding relay device next time when the broadcast message is received.
It should be noted that, in other embodiments, if it can be ensured that the relative position between the relay device and the bluetooth device is not changed, the binding list may be updated only when a new bluetooth device joins the lan, and not updated at other times.
Or in other embodiments the binding list may also be updated manually by the user installing a new device, i.e. for a newly networked bluetooth device it is not necessary to send a broadcast message.
It can be understood that, when the gateway device needs to actively send a message to a certain bluetooth device, it also determines a relay device corresponding to the bluetooth device, and then sends the message to the corresponding relay device, so as to forward the message to the bluetooth device by using the corresponding relay device.
