Detailed ways

The principles and spirit of the present invention are described below with reference to a few exemplary embodiments. It is to be understood that the embodiments are presented only to enable those skilled in the art to understand the invention. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Those skilled in the art will appreciate that embodiments of the present invention can be implemented as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of full hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

In accordance with an embodiment of the present invention, a method and apparatus for pairing wireless devices and computing devices are presented.

The principles and spirit of the present invention are explained in detail below with reference to a few representative embodiments of the invention.

It should be noted that the following embodiments of the present disclosure use the server (SERVER) and the client (CLIENT) to respectively represent one and the other of the control device and the controlled device, but are not limited thereto. For example, in the case of a multi-device, It includes a control device (such as a remote control) and a plurality of controlled devices (such as a drone). The server corresponds to the control device, and the client corresponds to the controlled device. For another example, in a scenario where multiple devices are controlled, including a controlled device (such as a drone) and multiple control devices (such as a remote controller), the server corresponds to the controlled device, and the client corresponds to the control. device. In an embodiment, the control device and the controlled device may determine whether the server or the client corresponding to the following embodiment is determined by burning corresponding firmware or installing corresponding software according to different application scenarios.

For the sake of versatility, the following embodiments of the present disclosure describe the pairing process by the server and the client, without limiting whether the two are control devices or controlled devices, respectively.

FIG. 1 is a flowchart of a pairing method of a wireless device according to an embodiment of the present disclosure. The method of this embodiment can be applied to a server to be paired with a plurality of clients. As shown in FIG. 1, the method of this embodiment includes the following steps S101-S103.

In step S101, the server enters the pairing state and pairs with the current client.

In this step, the server and all clients to be matched enter the pairing state. Taking the application scenario of the drone as an example, the drone itself can enter the pairing state by pressing the button, and the remote controller can enter the pairing state through the application (App) or the shortcut button.

In an embodiment, the step S101 for the current client's pairing process is shown in FIG. 2, and may include the following steps S201-S203.

In step S201, the server receives the pairing request sent by the current client.

When the server enters the pairing state with the current client, the two parties communicate using the agreed frequency, bandwidth, device ID, and scrambling code, and the client searches for the server. After the client confirms the search to the server, the pairing process starts. First, the client sends a pairing request to the server. In one embodiment, the pairing request carries, but is not limited to, the device type and device ID of the current client.

In this embodiment, since there are multiple clients to be paired with the server at the same time, it may happen that the server receives the pairing request sent by other clients in the process of pairing with the current client. In order to avoid interference with the pairing of the server and the current client, in an embodiment, in this step S201, the server can immediately start a timer (TIMER) when receiving the pairing request sent by the current client, in the timer If the pairing request of other clients is received within the preset time length, it will be directly ignored until the current pairing process is completed or the timer expires before the new pairing request sent by the next client can be received and processed.

In step S202, the server sends a pairing setting to the current client.

After receiving the pairing request sent by the current client, the server sends the corresponding pairing settings to it. In one embodiment, the pairing settings carry, but are not limited to, the device type of the server, the device ID, the device number assigned to the current client, and the link key with the current client.

In step S203, the server receives the pairing confirmation of the current client feedback to complete the pairing with the current client.

After receiving the paired device sent by the server, the current client will return a pairing confirmation to the server to complete the pairing. In one embodiment, the pairing confirmation carries, but is not limited to, its own device ID and the device number assigned to itself by the server extracted from the paired device.

In step S102, after the server completes pairing with the current client, the server automatically enters the pairing state again to pair with the next client.

In the related art, after the server completes pairing with a certain client, the pairing state is ended and the normal working state is entered. In the working state, for example, it is ready to receive the user's operation and issue corresponding control commands to the paired client. In this embodiment, after the server completes pairing with the current client, it will automatically enter the pairing state again and prepare to pair with the next client. The pairing process with the next client can directly refer to the embodiment of step S101, for example, the next client is regarded as the current client to perform the pairing process of steps S201-S203.

In step S103, the server ends the pairing state and enters the working state according to the user operation or system configuration, or after pairing with multiple clients.

In the related art, the server ends the pairing state and enters the working state after completing the pairing with a certain client. In this embodiment, the server is determined according to the user operation or system configuration or is determined to be associated with all the clients to be paired. After the pair completes the pairing, it ends the pairing state and enters the working state. For example, after the user determines that all the clients to be paired have been paired, the user can manually reset the server to enter the normal working state. For another example, the server automatically resets to the normal working state when it determines that the number of the paired clients reaches the upper limit of the connected devices allowed by itself. For another example, when the server does not receive a new pairing request within a predetermined period of time (and thus can determine that all clients are paired), the server automatically resets to a normal working state.

FIG. 3 is a flowchart of a pairing method of a wireless device according to another embodiment of the present disclosure. The method of this embodiment can be applied to a server that has been paired with a plurality of clients. As shown in FIG. 3, the method of this embodiment includes the following steps S301-S303.

In step S301, the server saves and presents a list of a plurality of clients.

In one embodiment, the server may store pairing information of multiple clients and provide them to the server users in the form of a list. Taking a multi-machine application scenario of the drone as an example, the remote control device can present the above list to the user through its own screen or through a corresponding application. The client list may include, for example, a corresponding client device ID and a device number assigned by the server to each client, thereby facilitating the user to operate on the specific client through the list.

In step S302, the server receives an operation of the user on the at least one client in the list.

The user may select one or more clients in the list presented by the server to perform various operations, such as but not limited to deletion operations, selected operations, and rename operations, etc., and enter different subsequent steps according to different operation types. .

In step S303, the corresponding at least one client is deleted in the broadcast enabled access device according to the deletion operation of the user, so that the at least one client cannot find the server.

The user can select one or more clients in the list to delete according to actual needs. For example, if the server connected to the device reaches the upper limit, the user may select one or more clients in the list. In order to prevent the deleted client from subsequently attempting to access the server and causing interference to other devices, in one embodiment, the server may broadcast the access device information that allows access (ie, pairing), for example, by means of encrypted communication. (such as including the device ID and device number), and delete one or more clients selected by the user. In this way, after receiving the broadcasted device information, the deleted client finds that it is not in the allowed access device, for example, by deleting the server device ID saved by itself. The way to achieve subsequent can not be found on the server.

In step S304, the corresponding at least one client is controlled according to the selected operation of the user, so that the at least one client responds to prompt the user.

In the related art, in a scenario of controlling multiple devices, even if a user selects a certain device of the terminal through the control device, the selected object cannot be known in time. For example, in a scenario where multiple drones are controlled by one remote controller, when the user switches the selected drone, it may only know which drone is selected after re-entering the instruction of the specific flight operation. This creates a situation where the danger cannot be handled in a timely manner. In this embodiment, after the user selects one of the clients through the list, the server can automatically issue an instruction to the client, so that the client makes a specific response, such as by flashing, buzzing, or performing a specific flight. Actions (such as rotation, rising), etc., to achieve the effect of prompting the user. According to the embodiment, in an application scenario of a multi-device such as a drone, the operator can quickly locate the target device from the plurality of controlled devices to implement precise control.

In step S305, at least one client in the list is renamed according to the user's rename operation.

According to specific needs, the user may also perform a rename operation for one or more clients in a list provided by the server, for example, according to the color, shape and the like characteristics of the client or according to the user preference, different clients are given different names. Thereby facilitating subsequent operations such as selected control.

As described above, steps S301-S305 involve the communication between the server and the plurality of clients after the matching is completed. In an embodiment, an uplink message (such as a response message) sent by multiple clients to the server may implement multiple access communication by using related technologies such as time division, frequency division, and code division; and the server to the client may broadcast and The method of on-demand broadcasts downlink messages (such as control messages). For example, the downlink broadcast data sent by the server is formed by grouping the corresponding client identifier (for example, the device number assigned by the server) for the data of each client, and the client is based on the identity of the packet in the data of the packet. The broadcast data is extracted to its own data and discarded to other clients' data. Further, for example, in a controlled multi-machine scenario of the drone, the remote controller can selectively control all the drones or control one or several drones, and accordingly, the remote controller broadcasts to the drones. The flight control command carries the device number of the target drone. Only the selected drone can extract the corresponding flight control command from the broadcast data in response to the joystick operation of the remote controller, while the unmanned drone is suspended. Stop or perform an automatic flight.

In addition, the communication between the server and the client in the above embodiment is described by taking the direct encrypted communication between the two as an example, but the disclosure is not limited thereto. In an embodiment, both the server and the client are provided with a network access device (such as a wireless network card or a 3G/4G communication module), so that the two can be connected via a public network (such as the Internet or a 3G/4G mobile data network) and A private server (such as a server provided by a device manufacturer) completes the pairing process, and the pairing information can be stored and completed through the above-mentioned private server, thereby protecting the privacy of the user and ensuring the security of the device.

It should be noted that, although the various steps of the method of the present disclosure are described in a particular order in the drawings, this does not require or imply that the steps must be performed in the specific order, or that all the steps shown must be performed. Achieve the desired results. Additionally or alternatively, certain steps may be omitted, multiple steps being combined into one step execution, and/or one step being decomposed into multiple step executions and the like.
