And under the condition of receiving the reconnection Bluetooth broadcast, disconnecting the connection with the first terminal, and sending a second Bluetooth broadcast, wherein the reconnection Bluetooth broadcast is sent by a second terminal, the second Bluetooth broadcast comprises second state information, and the second state information is used for indicating that the Bluetooth equipment is in a waiting connection state.
Specifically, the bluetooth device may detect a broadcast sent by a peripheral terminal, and if receiving a reconnected bluetooth broadcast, may disconnect the bluetooth connection with the current first terminal, and send out a second bluetooth broadcast, where the second bluetooth broadcast includes second state information to indicate that the bluetooth device is in a wait connection state, so as to notify the second terminal to connect.
In an alternative embodiment, the first bluetooth broadcast includes a first connection identifier of the bluetooth device, and the reconnected bluetooth broadcast includes a second connection identifier;
in the case of receiving a reconnected bluetooth broadcast, the method further comprises:
judging whether the received second connection identifier is consistent with the locally stored first connection identifier;
and if the connection is consistent with the first terminal, triggering the step of disconnecting the connection with the first terminal.
First, a first bluetooth broadcast sent by a bluetooth device may include a first connection identifier of the bluetooth device, such as a physical address of the bluetooth device; the terminal receiving the first bluetooth broadcast can obtain the first connection identifier, and can send out a reconnected bluetooth broadcast to the bluetooth device under the selection operation of the user, and the reconnected bluetooth broadcast can also include the first connection identifier of the bluetooth device so as to be accurately connected to the bluetooth device. The connection identifier included in the transmission of the reconnected Bluetooth broadcast is described by a second connection identifier.
Specifically, when the bluetooth device in the connected state receives the bluetooth broadcast a, it may be determined whether the bluetooth broadcast is a reconnected bluetooth broadcast for itself through the second connection identifier, that is, if the received second connection identifier is consistent with the locally stored first connection identifier, the step of disconnecting the connection with the first terminal may be triggered; if the received second connection identifier is inconsistent with the locally stored first connection identifier, it indicates that the currently received bluetooth broadcast a is not a reconnected bluetooth broadcast for the bluetooth device, and the connection with the first terminal may not be disconnected.
Through the steps, the Bluetooth device in the connected state can judge the detected Bluetooth broadcast, the connection with the current terminal is disconnected when the reconnection Bluetooth broadcast aiming at the Bluetooth device is detected, preparation is made for reconnection to a new terminal, the detected Bluetooth broadcast can be ignored when the reconnection Bluetooth broadcast aiming at the Bluetooth device is not detected, and the disconnection with the current terminal under the unnecessary condition is avoided.
In an optional embodiment, the method further comprises:
and under the condition that the time length for sending the second Bluetooth broadcast reaches the first preset time length, if the second Bluetooth broadcast is not connected, switching to sending a third Bluetooth broadcast.
Wherein the third bluetooth broadcast may include third status information indicating that the bluetooth device is in an unconnected state. If the bluetooth device detects that the duration for sending the second bluetooth broadcast reaches the first preset duration and is not connected all the time, it may be determined that the bluetooth wait connection is overtime, and does not wait for the connection of the second terminal, and switch to send the third bluetooth broadcast, that is, switch from the wait connection state to the unconnected state, and at this time may be connected by any terminal (which may include the second terminal), and execute the connection mode in this state, which is not described herein again.
In an optional implementation manner, in the case of receiving the reconnected bluetooth broadcast, before disconnecting the connection with the first terminal, the method further includes:
sending a disconnection notice to the first terminal, wherein the disconnection notice is used for prompting that the Bluetooth connection with the first terminal is to be disconnected;
and if a confirmation instruction for the disconnection notification is received or the feedback information for the disconnection notification is not received within a second preset time, triggering the step of disconnecting the first terminal.
The bluetooth device may notify the first terminal before disconnecting from the first terminal. Specifically, a disconnection notification may be sent to the first terminal, and the disconnection is performed after the bluetooth device is prompted to disconnect the bluetooth connection to the first terminal. Optionally, the disconnection notification may be a message prompt such as a notification bar displayed on the first terminal, which is not limited herein.
Alternatively, the disconnection may be performed only after confirmation by the first terminal, i.e. after the first terminal receives the disconnection notification, the user may choose to confirm the disconnection or refuse the disconnection. If the disconnection is confirmed, the first terminal sends a confirmation instruction to the Bluetooth device, and the Bluetooth device can disconnect the Bluetooth connection with the first terminal; if disconnection is refused, the first terminal sends a refusing instruction to the Bluetooth device, and the Bluetooth device can not disconnect the Bluetooth connection with the first terminal. Optionally, if the bluetooth device does not receive the feedback information of the disconnection notification within the second preset time period, that is, the first terminal does not make any feedback, the step of disconnecting the connection with the first terminal may be triggered.
Through the steps, the user can receive a prompt before the Bluetooth equipment disconnects the terminal, and can also select whether disconnection is allowed or not, so that some situations that other terminals are not expected to be connected to the Bluetooth equipment can be avoided.
103. And receiving a connection request, and judging whether the connection request comes from the second terminal.
If the terminal detects the second bluetooth broadcast, that is, the terminal determines that the bluetooth device is in the connection waiting state through the state information therein, a connection request may be sent to the bluetooth device. The bluetooth device may receive the connection request and determine whether the connection request comes from the second terminal, and if so, may perform step 104; if not, step 104 may not be executed, and the connection of the second terminal may be continuously waited for.
In an alternative embodiment, the reconnected bluetooth broadcast further includes a first connection password; in the case that the second connection identifier received by the bluetooth device is consistent with the locally stored first connection identifier, the method further includes:
saving the first connection password;
the connection request includes a second connection password; judging whether the connection request comes from the second terminal, including:
judging whether the second connection password is consistent with the first connection password or not; if so, the connection request comes from the second terminal, and if not, the connection request does not come from the second terminal.
Specifically, the reconnected bluetooth broadcast sent by the terminal to the bluetooth device may include a first connection password, and optionally, the connection password may include, but is not limited to, a random 6-bit password, a physical address of the terminal, or other unique identification of the terminal. If the bluetooth device detects a reconnected bluetooth broadcast, under the condition that the received second connection identifier is consistent with the locally stored first connection identifier, the first connection password can be stored so as to be verified when a subsequent terminal sends a connection request, and specifically, whether the connection password in the connection request is consistent with the connection password in the reconnected bluetooth broadcast is judged, so that whether the terminals requesting connection before and after verification are the same terminal is verified, and the connection is performed only when the terminals are the same terminal, so that the connection to other terminals is avoided. The connection password included for issuing the reconnected Bluetooth broadcast is distinguished by a second connection password.
For example, the second terminal scans a second bluetooth broadcast (waiting for connection state) sent by the bluetooth device, initiates a connection request, and can send a second connection password again, so that the bluetooth device is compared with the first connection password stored during the reconnection of the bluetooth broadcast, and the bluetooth device is successfully reconnected after the information that the bluetooth device is successfully compared is obtained.
104. If receiving the connection request from the second terminal, establishing Bluetooth connection with the second terminal, and executing the step of sending the first Bluetooth broadcast.
If it is determined that the connection request is from the second terminal, a connection may be established with the second terminal, and a first bluetooth broadcast may be sent out after the connection is established with the second terminal, which indicates that the bluetooth device is in a connected state, and on this basis, bluetooth connection switching may be performed again, that is, step 102 to step 104 may be repeatedly performed, which is not described herein again.
If the connection request does not come from the second terminal, the connection request may not be made with the terminal (referred to as a third terminal herein) that sent the connection request; optionally, the bluetooth device may also display the prompt information, and select whether to connect with the third terminal through manual operation.
The device operating in the Master device mode is called a Master device (Master), and can search surrounding devices and select a Slave device (Slave) to be connected to connect. The Bluetooth module working in the slave mode can only be searched by the host and can not actively search, and the slave device can also transmit and receive data with the host device after being connected with the host. In the use process of a common Bluetooth device, a terminal (APP) is used as a Master, the Bluetooth device is used as a Slave, the function of the APP for controlling the Bluetooth device is realized, however, after the Bluetooth device is connected by the APP, other APPs are not allowed to be connected with the Bluetooth device to control the Bluetooth device, most of the devices are near the Bluetooth device in actual scene application, and the APP cannot be used for discovering and controlling the devices.
The bluetooth connection switching method in the embodiment of the application is applied to bluetooth equipment and can send out a first bluetooth broadcast, wherein the first bluetooth broadcast comprises first state information, and the first state information is used for indicating that the bluetooth equipment is in a connected state; under the condition of receiving the reconnection Bluetooth broadcast, disconnecting the connection with the first terminal and sending out a second Bluetooth broadcast; the reconnection Bluetooth broadcast is sent by a second terminal, the second Bluetooth broadcast comprises second state information, and the second state information is used for indicating that the Bluetooth equipment is in a waiting connection state; if a connection request from the second terminal is received, Bluetooth connection is established with the second terminal, the step of sending the first Bluetooth broadcast is executed, the Bluetooth equipment can be switched from one terminal to another terminal without the need of operating the Bluetooth equipment by a user, and convenient and quick Bluetooth connection switching is achieved.
For example, when the mobile phone a is connected to the bluetooth device, the mobile phone B is allowed to disconnect the bluetooth device from the mobile phone a without manually operating the bluetooth device and the mobile phone a, so that the mobile phone B is connected to the bluetooth device. In addition, when the terminal scans the broadcast of the Bluetooth device, the connection state of the current Bluetooth device can be known.
