Detailed Description
The core of the application lies in providing the Bluetooth equipment and the Bluetooth state switching method and device thereof, so as to effectively improve the connection speed of the Bluetooth equipment with the control terminal after disconnection, and ensure the performance stability of the Bluetooth equipment.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all 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.
Currently, in actual use, the situation that a bluetooth device such as a TWS speaker is disconnected from a control terminal such as a mobile phone may occasionally occur, including active disconnection, and sudden disconnection caused when the placement position of the bluetooth device exceeds an effective communication distance or a bug occurs in an internal program. In the prior art, for disconnected bluetooth devices, the recovery, i.e., the reconnection, of the connection between the disconnected bluetooth devices and the control terminal often takes a certain time, so that the efficiency is low, and the user experience is poor. In view of this, the present application provides a bluetooth state switching scheme for a bluetooth device, which can effectively solve the above problems.
Referring to fig. 1, an embodiment of the present application discloses a bluetooth state switching method for a bluetooth device, where the bluetooth device includes a master device and a slave device connected based on a bluetooth link, and the method includes:
s101: the main device generates a first switching command after detecting that the Bluetooth connection with the control terminal is disconnected, so that the Bluetooth state of the main device is switched into a connectable state.
It should be noted that the master device is a device that performs various logic judgments and function control, and the bluetooth connection and communication with the control terminal (such as a mobile phone, a bracelet, etc.) are also handled by the master device. A slave device is a device that follows the master device for the same operation. For example, when the master device performs a shutdown operation after being determined by the logic processing, the slave device will also perform the shutdown operation following the master device.
After the bluetooth device is connected with a certain control terminal, in order to guarantee the working performance of the bluetooth device and reduce power consumption, the bluetooth device usually sets the bluetooth state to a non-connectable state. In the non-connection state, the Bluetooth chip does not send out connection broadcast, and does not respond or reply when other control terminals attempt to perform Bluetooth connection.
Therefore, in the application, after the bluetooth connection between the master device and the control terminal is disconnected, the master device generates a first switching command to switch the bluetooth state of the master device to a connectable state. In the connectable state, the Bluetooth chip continuously sends out connection broadcast, and when the control terminal tries to connect, the Bluetooth chip responds and replies, thereby realizing quick connection back with the control terminal.
It should be added that the switching of the bluetooth state of the bluetooth device may be managed by means of a state machine. In addition, the bluetooth status only specifically relates to whether the bluetooth device is connectable, and in practical applications, those skilled in the art may further enrich the setting based on the above content according to actual needs, for example, the bluetooth device may be specifically set to be in a non-discoverable and non-connectable state during the successful bluetooth connection between the bluetooth device and the control terminal, and after the bluetooth device is disconnected from the control terminal, the bluetooth device is switched to be in the non-discoverable and connectable state based on the first switching command.
S102: the master device sends a first switching command to the slave device so that the slave device performs Bluetooth state switching.
As described above, the slave device should perform a corresponding operation following the master device, so the master device sends a first switch command to the slave device so that the slave device is also switched to the connectable state.
S103: the slave equipment acquires the actual Bluetooth state of the master equipment and judges whether the actual Bluetooth state is a connectable state or not; if not, the process proceeds to S104.
S104: the slave device sends a first switching command to the master device, and updates and acquires the actual Bluetooth state of the master device until the actual Bluetooth state acquired by updating is a connectable state.
It should be noted that, since the master device is different from the slave device and needs to be responsible for many logical processes and function control, the internal program process is complicated. Therefore, in some special cases, the master device may not actually execute the first switch command, i.e., does not actually switch the bluetooth status to the connectable status, which still affects the connection back efficiency between the bluetooth device and the control terminal.
In view of the foregoing situation, in the bluetooth state switching method provided in the embodiment of the present application, a monitoring mechanism for the slave device to switch the bluetooth state of the master device is specifically set: the slave device requests the master device to acquire the actual Bluetooth state of the master device, and checks the actual Bluetooth state of the master device to judge whether the master device is in a connectable state.
If the actual bluetooth state of the master device is indeed the connectable state, it indicates that the bluetooth state is switched normally, and at this time, the fast connection back with the control terminal can be realized. If the actual bluetooth state of the master device is not the connectable state, the slave device will send a first switching command to the master device, so that the master device performs the bluetooth state switching operation corresponding to the first switching command again. When the actual bluetooth state of the master device is indeed switched to the connectable state, the slave device stops updating and verifying the actual bluetooth state of the master device and the related operation of sending the first switching command.
It should be noted that, the first switch command in this application means a command that can cause the command receiving side to switch the bluetooth state to the connectable state, and the sender and the receiver of the command are not particularly limited.
The method for switching the Bluetooth state of the Bluetooth equipment provided by the embodiment of the application comprises the following steps: the method comprises the steps that after the main device detects that the Bluetooth connection with a control terminal is disconnected, a first switching command is generated so that the Bluetooth state of the main device can be switched to a connectable state; the master device sends a first switching command to the slave device so that the slave device can carry out Bluetooth state switching; the slave equipment acquires the actual Bluetooth state of the master equipment and judges whether the actual Bluetooth state is a connectable state or not; if not, the slave device sends a first switching command to the master device, and updates and acquires the actual Bluetooth state of the master device until the actual Bluetooth state acquired by updating is a connectable state.
Therefore, the Bluetooth state switching method of the Bluetooth device provided by the application monitors and verifies the Bluetooth state switching of the master device by using the slave device, effectively ensures that the master device is timely switched to a connectable state after being disconnected with the control terminal, further effectively improves the back connection efficiency of the Bluetooth device after being disconnected with the control terminal, and ensures the Bluetooth connection stability of the Bluetooth device.
Referring to fig. 2, an embodiment of the present application discloses another bluetooth state switching method for a bluetooth device, where the bluetooth device includes a master device and a slave device connected based on a bluetooth link, and the method includes:
s201: after detecting that the Bluetooth connection with the control terminal is disconnected, the main device inquires a Bluetooth pairing record of the main device and the control terminal in a preset FLASH.
S202: the master device judges whether a record of successful Bluetooth pairing exists; if yes, entering S203; if not, the process proceeds to S209.
S203: the master device generates a first switching command so as to switch the Bluetooth state of the master device to a connectable state; the process proceeds to S204.
Specifically, in this embodiment, after the master device is disconnected from the control terminal, the switching command is generated according to whether a record that the bluetooth pairing with the control terminal is successful is stored in the preset FLASH. If the record of successful Bluetooth pairing is reserved in the preset FLASH, the connection state is switched to be in a connectable state through a first switching command.
S204: the master device sends a first switching command to the slave device so that the slave device can switch the Bluetooth state; the process proceeds to S205.
S205: the slave equipment judges whether a preset time length passes or not; if yes, entering S206; if not, the process returns to S205.
Specifically, in this embodiment, the slave device may update and acquire the actual bluetooth state of the master device every preset time period to check until the updated and acquired actual bluetooth state is the connectable state.
S206: the slave device acquires the actual Bluetooth state of the master device; the process proceeds to S207.
S207: the slave equipment judges whether the actual Bluetooth state is a connectable state or not; if not, the process proceeds to S208.
S208: the slave device sends a first switching command to the master device; the process proceeds to S205.
S209: the master device generates a second switching command so as to switch the Bluetooth state of the master device into a non-connectable state; the process proceeds to S210.
Specifically, in this embodiment, if there is no record of successful bluetooth pairing in the preset FLASH (some bluetooth devices may be provided with a mechanism for automatically clearing the record after disconnection), it is not necessary to switch to the connectable state, and therefore, the master device may switch to the non-connectable state by using the second switch command.
Similarly, the second switch command in the present application means a command that can cause the command receiver to switch the bluetooth state to the non-connectable state, and it also does not specifically limit the sender and receiver of the command.
S210: and sending a second switching command to the slave device so as to switch the Bluetooth state of the slave device to the non-connectable state.
