Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The existing Bluetooth locks with partial models can not be connected for a long time, and if the problem is improved by adopting a method of waking up a system by touching keys and then broadcasting like many existing Bluetooth locks, the convenience of the Bluetooth is lost; if such a problem is improved by reducing the broadcasting interval, power consumption may be increased. Therefore, an object of the present invention is to provide a bluetooth connection method, apparatus, bluetooth device and system, which achieve a compromise between bluetooth power consumption and convenience by obtaining terminal address information when a terminal scan request is received and reducing a broadcast interval when the terminal address information is consistent with pre-stored address information.
The following embodiments can be applied to the bluetooth connection system shown in fig. 1, where the system shown in fig. 1 includes a bluetooth device 10, a terminal 20 communicatively connected to the bluetooth device 10, and a cloud server 30 communicatively connected to the terminal 20, the bluetooth device 10 communicates with the terminal 20 by bluetooth, the bluetooth device 10 at least has a bluetooth module for sending and receiving bluetooth signals, the terminal 20 communicates with the cloud server 30 by mobile, the bluetooth device 10 can indirectly communicate with the cloud server 30 by using the terminal 20 as an intermediary, the cloud server 30 is used for managing the bluetooth device 10 and the terminal 20, for example, the cloud server 30 can be used for managing the device address, unlock password, authorized user information, etc. of the terminal, the terminal 20 can log into the cloud server 30 by APP, public number and/or applet to establish a communication connection with the cloud server 30, the terminal 20 may also manage the bluetooth device 10 through APP, public numbers and/or applets.
It should be noted that the configuration shown in fig. 1 is not intended to limit the bluetooth connection system, and in other embodiments, the bluetooth connection system may include fewer or more components than those shown, or some components may be combined, or a different arrangement of components may be used.
Example one
Referring to fig. 2, a bluetooth connection method according to a first embodiment of the present invention is shown, which is applied to a bluetooth device, where the bluetooth device can be implemented by software and/or hardware, and the method includes specific steps S01-S04.
In step S01, broadcasting is performed through a first preset broadcasting interval.
It should be noted that bluetooth is a communication protocol based on data packets and having a master-slave architecture, and bluetooth generally sends a broadcast packet at a preset time interval so that peripheral devices can search for and connect to the bluetooth. The broadcast interval is the interval for transmitting the broadcast packet by the bluetooth, and the shorter the broadcast packet transmission interval time is, the more frequent the broadcast packet transmission is represented, and the lower the broadcast interval is.
Specifically, the first preset broadcast interval may be a maximum broadcast interval during which bluetooth is satisfied with operation, for example, bluetooth may transmit broadcast packets at an interval of 1 second, so that it may be ensured that bluetooth is in a low power consumption state during a time other than bluetooth broadcast. Taking the Nordic nRF52810 bluetooth chip as an example, if broadcast packets are sent at 1 second intervals, when the broadcast packet data is 3 bytes and the transmission power is 0dBm, the power consumption of the broadcast is only 15 uA.
Step S02, receiving a scanning request sent by the terminal, where the scanning request carries terminal address information.
It should be noted that, according to the bluetooth standard, in the bluetooth connection process, when the terminal monitors the "broadcast packet" of the bluetooth device, the terminal sends the "scan request packet", and after receiving the "scan request packet", the bluetooth device replies a "scan response packet", and the whole process is as shown in fig. 3. The scan request packet includes the address of the bluetooth device of the scanner, i.e., the terminal, as shown in fig. 4. Based on this, the terminal address information can be directly extracted from the scan request transmitted from the terminal.
And step S03, judging whether the terminal address information is consistent with the pre-stored address information.
When the terminal address information is judged to be consistent with the pre-stored address information, executing step S04; and when the terminal address information is judged to be inconsistent with the pre-stored address information, not acting and continuing to broadcast at a first preset broadcast interval.
Specifically, the pre-stored address information is address information recorded on the bluetooth device, and is generally terminal address information of an authorized user, and the pre-stored address information may be recorded in the bluetooth device in a manner that the authorized user registers by himself, or the bluetooth device may record the terminal address information by himself after the bluetooth device is successfully connected to the terminal for the first time, or the bluetooth device may authenticate the address information of the terminal through the cloud terminal after the bluetooth device is successfully connected to the terminal for the first time, and record the terminal address information by himself after the bluetooth device is successfully authenticated.
Step S04, adjusting the first preset broadcast interval to a second preset broadcast interval, and performing broadcasting, where the second preset broadcast interval is lower than the first preset broadcast interval.
It should be noted that, after the address matching is successful, the terminal currently sending the scanning request is characterized as an authorized user terminal, and in order to accelerate the subsequent bluetooth connection speed, the broadcast interval is reduced from the first preset broadcast interval to the second preset broadcast interval, so that the broadcast packet is sent more frequently. The second preset broadcast interval may be any interval value smaller than the first preset broadcast interval, for example, the second preset broadcast interval may be a broadcast interval obtained by multiplying the preset first broadcast interval by a preset ratio (e.g., 60%).
To sum up, the bluetooth connection method in this embodiment, through obtaining the terminal address information when receiving the scanning request of the terminal, and when the terminal address information is consistent with the address information that prestores, reduce the broadcast interval, so that the terminal can connect the bluetooth fast, both can improve the problem that the bluetooth of some models can not be connected for a long time like this, and still guaranteed the convenience of bluetooth, because the broadcast of low interval only lasts when initiating the connection, and not all be in the broadcast of low interval all the time, the low-power consumption of bluetooth has been guaranteed, thereby has realized giving consideration to between bluetooth power consumption and the convenience.
Example two
Referring to fig. 5, a bluetooth connection method according to a second embodiment of the present invention is shown, which is applied to a bluetooth device, where the bluetooth device can be implemented by software and/or hardware, and the method specifically includes steps S11 to S17.
In step S11, broadcasting is performed through a first preset broadcasting interval.
Step S12, receiving a scanning request sent by the terminal, where the scanning request carries terminal address information.
And step S13, judging whether the terminal address information is consistent with the pre-stored address information.
When the terminal address information is judged to be consistent with the pre-stored address information, executing step S14; and when the terminal address information is judged to be inconsistent with the pre-stored address information, not acting and continuing to broadcast at a first preset broadcast interval.
Step S14, adjusting the first preset broadcast interval to a second preset broadcast interval, and performing broadcasting, where the second preset broadcast interval is lower than the first preset broadcast interval.
And step S15, detecting whether the connection between the Bluetooth device and the terminal is successful within the preset time.
When it is detected that the bluetooth device and the terminal are not successfully connected within the preset time, step S16 is executed, and when it is detected that the bluetooth device and the terminal are successfully connected within the preset time, a preset action after the connection is successfully performed may be executed, for example, when the bluetooth device is a bluetooth lock, if the terminal is successfully connected with the bluetooth lock within the preset time, the bluetooth lock may execute an unlocking action.
Step S16, adjusting the second broadcast interval to the first preset broadcast interval, and performing broadcasting.
It should be noted that, when the bluetooth device and the terminal are not successfully connected within the preset time (e.g. 5s), in order to ensure low power consumption of the bluetooth, the broadcast interval of the bluetooth is reset to the first preset broadcast interval, so that the bluetooth operates in the low power consumption state.
In some optional embodiments of the present invention, when it is detected that the bluetooth device and the terminal are not successfully connected within the preset time, the following steps may be further performed:
and adjusting the second broadcast interval to a third preset broadcast interval, and broadcasting, wherein the third preset broadcast interval is lower than the second preset broadcast interval, namely when the connection is not successful after overtime, the broadcast interval is continuously reduced, so that the connection between the Bluetooth equipment and the terminal is successful as soon as possible. In specific implementation, the broadcast interval may be reduced according to a preset adjustment ratio, for example, when the connection is not successful for the first timeout, the broadcast interval is reduced by 5% and broadcasting is continued, and if the connection is not successful for the second timeout, the broadcast interval is reduced by 5% and broadcasting is continued until the adjustment times reach the set times or the broadcast interval reaches a preset minimum broadcast interval.
In summary, compared with the first embodiment, after the broadcast interval is decreased to the second broadcast interval, the present embodiment monitors whether the connection between the bluetooth device and the terminal is successful within the preset time, and if the connection is not successful, the broadcast interval is adjusted back to the first broadcast interval, so that the bluetooth is in the low power consumption state.
Further, the method may further include:
sending an authentication request to a cloud end, wherein the authentication request carries terminal address information;
when the authentication is successful, the terminal address information is stored;
and when the authentication fails, disconnecting the connection, adjusting the second broadcast interval to the first preset broadcast interval, and broadcasting.
Specifically, in implementation, after the bluetooth device is connected to the terminal, the bluetooth device sends an authentication request including terminal address information to the cloud, the cloud determines whether the terminal is an authorized user according to the terminal address information, if the terminal is determined as an authorized user, the authentication is successful, the bluetooth device stores the terminal address information by itself and keeps bluetooth connection, so that the bluetooth device can be successfully connected to the terminal subsequently, if the terminal is determined as an unauthorized user, the authentication is failed, the bluetooth device is disconnected, and the broadcast interval is adjusted back to the first broadcast interval, so that the bluetooth device is ensured to be in low power consumption.
Further, the pre-stored address information includes fixed address information and variable address information, and the method may further include:
when the terminal address information is inconsistent with the pre-stored address information, judging whether the storage amount of the pre-stored address information exceeds a preset amount;
and if so, replacing the terminal address information with the variable address information.
The terminal address information and the pre-stored address information can be judged whether to be consistent when the terminal address information is stored.
The fixed address information may be address information of a fixed user, for example, a terminal address of an administrator, the variable address information may be changeable address information, for example, a terminal address of a temporary user, when the storage amount of the address information of the bluetooth device is excessive, the variable address information may be replaced with the current terminal address information to store the current terminal address information, and the variable address information selected for replacement may be variable address information that is used less frequently or used earliest. In specific implementation, the address information recorded by the bluetooth device can be stored in the list, and the address information can be arranged according to the sequence of the use times from high to low or the use sequence, so that the speed of subsequently replacing the variable address information can be increased, and the response speed is increased.
EXAMPLE III
In another aspect, the present invention further provides a bluetooth connection apparatus, please refer to fig. 6, which shows a bluetooth connection apparatus according to a third embodiment of the present invention, and the bluetooth connection apparatus is applied in a bluetooth device, where the bluetooth device can be implemented by software and/or hardware, and the apparatus includes:

and an interval adjusting module 14, configured to adjust the first preset broadcast interval to a second preset broadcast interval when it is determined that the terminal address information is consistent with the pre-stored address information, and perform broadcasting, where the second preset broadcast interval is lower than the first preset broadcast interval. And in addition, when the terminal address information is judged to be inconsistent with the prestored address information, the terminal does not act and continues to broadcast at a first preset broadcast interval.
It should be noted that bluetooth is a communication protocol based on data packets and having a master-slave architecture, and bluetooth generally sends a broadcast packet at a preset time interval so that peripheral devices can search for and connect to the bluetooth. The broadcast interval is the interval for transmitting the broadcast packet by the bluetooth, and the shorter the broadcast packet transmission interval time is, the more frequent the broadcast packet transmission is represented, and the lower the broadcast interval is.
Specifically, the first preset broadcast interval may be a maximum broadcast interval during which bluetooth is satisfactory to operate, for example, bluetooth may send broadcast packets at intervals of 1 second, so that it may be ensured that bluetooth is in a low power consumption state in a time other than bluetooth broadcast, and taking a Nordic nRF52810 bluetooth chip as an example, if broadcast packets are sent at intervals of 1 second, when broadcast packet data is 3 bytes and transmission power is 0dBm, power consumption of broadcast is only 15 uA.
It should be noted that, according to the bluetooth standard, in the bluetooth connection process, when the terminal monitors the "broadcast packet" of the bluetooth device, the terminal sends the "scan request packet", and after receiving the "scan request packet", the bluetooth device replies a "scan response packet", and the whole process is as shown in fig. 3. The scan request packet includes the address of the bluetooth device of the scanner, i.e., the terminal, as shown in fig. 4. Based on this, the terminal address information can be directly extracted from the scan request transmitted from the terminal.
Specifically, the pre-stored address information is address information recorded on the bluetooth device, and is generally terminal address information of an authorized user, and the pre-stored address information may be recorded in the bluetooth device in a manner that the authorized user registers by himself, or the bluetooth device may record the terminal address information by himself after the bluetooth device is successfully connected to the terminal for the first time, or the bluetooth device may authenticate the address information of the terminal through the cloud terminal after the bluetooth device is successfully connected to the terminal for the first time, and record the terminal address information by himself after the bluetooth device is successfully authenticated.
It should be noted that, after the address matching is successful, the terminal currently sending the scanning request is characterized as an authorized user terminal, and in order to accelerate the subsequent bluetooth connection speed, the broadcast interval is reduced from the first preset broadcast interval to the second preset broadcast interval, so that the broadcast packet is sent more frequently. The second preset broadcast interval may be any interval value within the rated broadcast interval of bluetooth, which is smaller than the first preset broadcast interval, for example, the second preset broadcast interval may be the rated broadcast interval of bluetooth or a broadcast interval obtained by multiplying the rated broadcast interval by a preset ratio (e.g., 60%).
To sum up, bluetooth connecting device in the middle of this embodiment, through acquireing terminal address information when the scanning request of receiving the terminal, and when terminal address information is unanimous with the address information that prestores, reduce the broadcast interval, so that this terminal can link up the bluetooth fast, the problem that the bluetooth long-time connection of part model can not be gone up both so, and still guaranteed the convenience of bluetooth, simultaneously because the broadcast of low-interval only lasts when initiating the connection, and not all be in the low-interval broadcast always, bluetooth power consumption has been guaranteed, thereby compromise between bluetooth power consumption and the convenience has been realized.
