S101a: when the master device acquires the slave device to connect with the master device, the master device reads the identity identifier of the slave device.

It should be noted that the identity of the slave device may be a physical address (MAC, Media Access Control) or a serial number, and the MAC address or the serial number is a unique identifier of the slave device, so the master device can pass such an identity. The identification completes the authentication of the slave device.

S102a: when the master device acquires that the slave device is disconnected from the master device by the connection, the master device pairs with the slave device by using the read identity of the slave device to implement wireless connection.

It should be noted that, in the embodiment of the present invention, pairing refers to establishing a wireless transmission channel between two devices to establish a data transmission link. It can be understood that the pairing belongs to the prior art and will not be described in detail herein.

However, the pre-pairing process provided by the present invention is not prior art, and pre-pairing refers to the identity authentication or identification of the master device to the slave device before the formal pairing, in preparation for formal pairing.

A method for automatically implementing a wireless connection between devices provided by an embodiment of the present invention. When the master device detects that a slave device is connected, the slave device requests the pairing, and then reads the identity of the slave device. When it is detected that the slave device is disconnected, the slave device has been unplugged, and the master device is paired with the slave device through the identity of the slave device that has been read to implement a wireless connection. Obviously, the method provided by the present application can automatically complete the method by detecting the connection state between the slave device and the master device. Wireless connection from the device. There is no need for the user to operate many steps to achieve pairing as in the prior art. This can release the user's multi-step operation on the master device and the slave device, and the user only needs to perform the plug-in operation of the slave device and the master device at one time, and the operation is convenient and simple.

Method Embodiment 2:

Referring to FIG. 1, FIG. 1 is a schematic diagram of Embodiment 2 of a method for automatically implementing wireless connection between devices provided by the present invention.

The method for automatically implementing a wireless connection between devices provided by this embodiment includes:

S101: The master device detects a level of the USB interface of the own device;

It should be noted that when the USB interface of the master device is not plugged into any device, that is, when the USB interface is in a floating state, the level of the USB interface is generally high; when a device is plugged into the USB interface of the master device, USB The level of the interface will change, for example from high to low, as long as the USB interface is plugged into the device, the low level of this interface will remain for a while. Of course, when the main device is plugged into the charger, as the time increases, the USB interface will have a charging pulse signal from the power source. The case where the main device is charged is not included in the embodiment of the present invention.

S102: When the level of the USB interface is at a first level and is maintained for a first predetermined time period, reading an identity of a slave device connected to the master device by using the USB interface; determining an identity of the slave device Whether it has been stored, if it is stored otherwise;

For example, the first level is a low level. If the low level of the USB interface is maintained for the first predetermined time period, the USB interface is plugged in from the device, and the master device can read the identity of the slave device, if not previously The identity is stored and stored.

S103: when the level of the USB interface changes from the first level to the second level, and the second level remains for the second predetermined time period, the master device turns on its own wireless control switch, and passes the already The stored identity of the slave device completes pairing with the slave device; the first level is opposite to the level state of the second level.

It should be noted that the wireless control switch in the embodiment of the present invention may be a Bluetooth switch or a WIFI switch, but is not limited to these two types.

When the master device detects a level jump and the jump becomes the second level for a second predetermined period of time, it indicates that the slave device is disconnected from the master device by the connection. It should be noted that the Bluetooth switch or the WIFI switch is only turned on when the master device needs to detect the level jump and the jump to the second level for the second predetermined time period. The master device does not simply detect that the USB interface is at the second level. Turn on the Bluetooth switch or WIFI switch straight. For example, the USB interface of the master device may remain at the second level when not accessed from the device. However, in this case, the master device does not turn on the Bluetooth switch or the WIFI switch.

For example, if the second level is a high level and the high level is maintained for a second predetermined period of time, then the slave device to which the master device USB interface is plugged in has been unplugged. Next, the master device needs to turn on the Bluetooth switch or the WIFI switch to complete the pairing with the slave device.

It should be noted that the first predetermined time period and the second predetermined time period are both predetermined time periods, and the two may be equal or not equal.

In summary, the method for automatically implementing wireless connection between devices provided by the present invention, the master device only needs to detect the level of its own USB interface, and can determine whether there is a slave device plugged in. When it is determined that there is a slave device plugged in, , indicating that the slave device is requesting pairing, then reading and storing the identity of the slave device completes the pre-pairing. When it is detected that the level of the USB interface changes to another level and remains for a predetermined time, the slave device has been unplugged, and the master device turns on its own Bluetooth switch or WIFI switch to automatically complete the pairing. Obviously, the method provided by the present application can automatically complete the Bluetooth pairing or WIFI pairing with the slave device by detecting the level change of the USB interface of the master device. There is no need for the user to operate many steps to achieve pairing as in the prior art. This can release the user's operation, and the user only needs to insert and remove the slave device and the master device at one time, which is convenient and simple.

It should be noted that, for the method provided by the embodiment of the present invention, the slave device needs to be plugged together with the master device through the data line, and then pulled out, and the master device detects the change of the level of the USB interface of the master device during the plugging and unplugging process; This data line only transmits signals, does not transmit current, and the master recognizes a level change. Therefore, the data line is different from the power line when charging the master device. Or the master device and the slave device can be directly plugged together without any data lines, and the interfaces of the two are matched to each other.

After the master device reads the identity of the slave device, the identity of the slave device can be stored together, so that the next time the same slave device is connected to the master device, the master device reads the identity of the slave device and determines that the slave device has been saved. With this identity, you no longer have to save the slave identity. It can be understood that, of course, the master device can read and save the identity of the slave device each time.

Referring to FIG. 3a, the figure is a flowchart of Embodiment 4 of a method provided by the present invention.

S301a: Obtain, from the device, whether the slave device is disconnected from the master device;

It should be noted that, in this embodiment, the slave device may not need to read and store the MAC code and the serial number of the master device, that is, the slave device does not need to authenticate the master device.

S302a: If yes, the slave device turns on its own wireless control switch to implement a wireless connection with the master device.

It should be noted that the wireless control switch in the embodiment of the present invention may be a Bluetooth switch or a WIFI switch, but is not limited to these two types.

In the method provided by the embodiment, when the slave device and the master device are wirelessly connected, the slave device only needs to determine whether it is disconnected from the master device. When the slave device is disconnected from the master device, the master device automatically turns on its own wireless device. Control the switch to achieve a wireless connection to the primary device. The process of implementing a wireless connection from a device is simpler than that of a master device. The slave device may not need to read the identity of the master device, and the slave device may not need to perform any action when connected to the master device. This is simpler than the multi-step operation of implementing wireless connections in the prior art.

It should be noted that the third predetermined time period may be the same as the first predetermined time period and the second predetermined time period, or may be different.

The predetermined level is a level state in which the USB interface of the slave device is not plugged together with the master device. That is, the slave device detects the level of its own USB interface. When it is at a predetermined level, it indicates that the slave device has been unplugged from the master device, and the slave device turns on its own Bluetooth switch or WIFI switch.

The slave device only needs to detect the level of its own USB interface to a predetermined level and maintain the third predetermined time period, and turn on its own Bluetooth switch or WIFI switch.

It should be noted that, in the method provided by the foregoing embodiment, the master device determines the connection state between the slave device and the master device by detecting the level of the USB, and the method provided in another embodiment of the present invention is: A predetermined sequence of numbers. The master device can determine whether the slave device is connected to the master device by reading the sequence of digits.

As long as the USB interface is plugged into the device, the low level of this interface will remain for a while. Of course, when the main device is plugged into the charger, as the time increases, the USB interface will have a charging pulse signal from the power source. The case in the embodiment of the present invention does not belong to the charging of the master device.

For example, the first level is a low level. If the low level of the USB interface is maintained for the first predetermined time period, the USB interface is plugged in from the device, and the master device can read the identity of the slave device, if not previously The identity is stored and stored.

For example, if the second level is a high level and the high level is maintained for a second predetermined period of time, then the slave device to which the USB interface is plugged in has been unplugged, and the pre-pairing process has been completed. Next, you need to turn on the Bluetooth switch or WIFI switch to complete the pairing with the slave device.

It should be noted that the first predetermined time period and the second predetermined time period are both predetermined time periods, and the two may be equal or not equal.

It should be noted that the third predetermined time period may be the same as the first predetermined time period and the second predetermined time period, or may be different.

The predetermined level is a level state in which the USB interface of the slave device is not plugged together with the master device. That is, after the slave device has been unplugged from the master device, the slave device detects the level of its own USB interface. When it is at a predetermined level, it indicates that the pre-pairing is completed, and turns on its own Bluetooth switch or WIFI switch.

It should be noted that, in this embodiment, the slave device does not need to read and store the MAC code and the serial number of the master device, that is, the slave device does not need to authenticate the master device. The slave device only needs to detect the level of its own USB interface to a predetermined level and maintain the third predetermined time period, and turn on its own Bluetooth switch or WIFI switch.

In summary, in the system provided by the present invention, the master device only needs to detect the level of the USB interface, and can determine whether there is a slave device. When it is determined that the slave device is plugged in, it indicates that the slave device is requesting pairing. Then read and store the identity of the slave device to complete the pre-pairing. When it is detected that the USB level changes to another level and remains for a predetermined time, it indicates that the slave device has been unplugged, and the master device turns on its own Bluetooth switch or WIFI switch to automatically complete the pairing. Obviously, this application provides The system, the master device can automatically complete the Bluetooth pairing or WIFI pairing with the slave device by detecting the level change of its own USB. There is no need for the user to operate many steps to achieve pairing as in the prior art. This can release the user's operation, and the user only needs to insert and remove the slave device and the master device at one time, which is convenient and simple.
