Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flowchart of a working method of a bluetooth device simulator according to an embodiment of the present invention, where an execution subject of the flowchart is the bluetooth device simulator in the implementation of the present invention. Referring to fig. 1, the working method of the bluetooth device emulator provided in this embodiment may include the following steps:
and S101, connecting with a host through a USB and carrying out USB soft disconnection with the host.
In this embodiment, the soft disconnection and the soft connection respectively refer to disconnection and connection of USB interface communication with a host through software configuration, and a physical connection between a USB interface of the bluetooth device emulator and the host exists all the time in a process of switching between the soft disconnection and the soft connection.
And step S102, establishing Bluetooth communication connection with the Bluetooth equipment.
In this embodiment, the bluetooth device includes, but is not limited to, electronic devices such as a usb key, a smart phone, an audio device, and a tablet computer with specific bluetooth functions. Establishing a bluetooth communication connection with a bluetooth device specifically includes:
the Bluetooth device simulator opens a Bluetooth searching function and detects whether a target Bluetooth device exists in the Bluetooth communication range of the Bluetooth device simulator;
if the target Bluetooth equipment exists, sending pairing request information to the target Bluetooth equipment;
receiving response information returned by the target Bluetooth equipment according to the pairing request information;
performing identity authentication on the target Bluetooth equipment according to the response information;
and if the verification is passed, establishing Bluetooth communication connection with the target Bluetooth equipment.
Preferably, in this embodiment, before sending the pairing request information to the target bluetooth device, the method may further include:
if the target Bluetooth equipment exists, judging whether the target Bluetooth equipment is accessed into the Bluetooth equipment simulator for the first time according to the equipment type of the target Bluetooth equipment;
if the Bluetooth device simulator is connected to the Bluetooth device simulator for the first time, entering the step of sending pairing request information to the target Bluetooth device;
if the target Bluetooth device is not connected to the Bluetooth device simulator for the first time, when the target Bluetooth device enters the Bluetooth communication range of the Bluetooth device simulator, the Bluetooth device automatically establishes Bluetooth communication connection with the target Bluetooth device.
Preferably, in this embodiment, after sending the pairing request information to the target bluetooth device, if response information that allows establishing bluetooth communication connection and is sent by the target bluetooth device is received, the bluetooth device simulator establishes bluetooth communication connection with the target bluetooth device, where the response information carries identification information used for authentication, and after receiving the response information, the target bluetooth device performs authentication on the target bluetooth device according to the identification information used for authentication carried by the target bluetooth device, and if the authentication passes, it indicates that the target bluetooth device allows establishing bluetooth communication connection with the bluetooth device simulator.
And step S103, carrying out USB soft connection with the host.
In this embodiment, when detecting that a new target bluetooth device establishes a bluetooth communication connection, the bluetooth device emulator is in soft connection with the host to "access" the new bluetooth device to the host, so that the host detects that a new device is plugged into the USB interface.
And step S104, responding to the USB standard request sent by the host, and returning the USB information of the Bluetooth equipment to the host.
Preferably, in this embodiment, the USB information may be fixed in the bluetooth emulator in advance, or may be dynamically matched.
When the USB information is dynamically matched, after step S102, the method further includes:
acquiring USB configuration information of the Bluetooth equipment;
before the returning the USB information of the Bluetooth device to the host, the method comprises the following steps:
and determining the USB information according to the USB configuration information.
Specifically, the USB configuration information may be key information such as USB protocol type, VID, PID, and the like, and other information may be dynamically matched inside the bluetooth emulator according to the key information. Therefore, the problem of poor performance caused by directly acquiring all USB information can be avoided.
In this embodiment, after the bluetooth device emulator performs the USB soft connection with the host, since the bluetooth device emulator requests to return the USB information of the bluetooth device to the host according to the USB standard of the host, the host recognizes the bluetooth device emulator as the bluetooth device. This enables the host and the bluetooth device to communicate data directly using the same protocol. Preferably, in this embodiment, the host includes, but is not limited to, a computer or other terminal device.
Step S105, receiving the instruction sent by the host, forwarding the instruction to the Bluetooth device, receiving the response data of the Bluetooth device, and forwarding the response data to the host.
In this embodiment, after the bluetooth device establishes the USB soft connection with the host through the bluetooth device emulator, the host may implement operation control on the bluetooth device through the bluetooth device emulator, and in this process, the working principle of the bluetooth device emulator is specifically as follows:
receiving an operation instruction issued by the host through the USB interface, and sending the operation instruction to the Bluetooth equipment through a Bluetooth channel;
and receiving response information of the Bluetooth equipment through the Bluetooth channel, and returning the response information to the host through the USB interface.
As can be seen from the above, in this embodiment, the USB is connected to the host through the USB, and the USB is in soft disconnection with the host; establishing Bluetooth communication connection with a Bluetooth device; carrying out USB flexible connection with the host; responding to the host to send a USB standard request, and returning USB information of the Bluetooth equipment to the host; the method comprises the steps of receiving an instruction sent by a host, forwarding the instruction to the Bluetooth device, receiving response data of the Bluetooth device, and forwarding the response data to the host, so that the Bluetooth device simulator can simulate the functions of pulling out and inserting the Bluetooth device into and out of the host through a USB interface through USB soft disconnection and USB soft connection, and for the host, the simulation method is basically consistent with the effect of directly inserting and pulling the Bluetooth device into and out of the host through the USB interface, so that host operation software can work without changing or changing a little, the upgrading cost is low, and the stability and the compatibility of a host system are basically not influenced; in addition, the invention also realizes the automatic switching of the Bluetooth equipment and improves the mass production efficiency.
Fig. 2 is a flowchart illustrating a method for operating a bluetooth device simulator according to another embodiment of the present invention. Referring to fig. 2, with respect to the previous embodiment, the working method of the bluetooth device emulator provided in this embodiment further includes:
and step S206, when the completion of the operation is detected, carrying out USB soft disconnection with the host computer, and destroying the Bluetooth communication connection with the Bluetooth equipment so as to establish Bluetooth communication connection with other Bluetooth equipment again.
Preferably, in this embodiment, the detecting that the job is completed includes:
and when an operation completion instruction sent by the host is received or when the Bluetooth communication connection with the Bluetooth equipment is detected to be disconnected, the operation is completed.
Preferably, in this embodiment, before establishing the bluetooth communication connection with the bluetooth device, the method further includes:
and acquiring the unique identifier of the Bluetooth device to be connected.
In this embodiment, since the unique identifier of the bluetooth device to be connected is obtained before establishing the bluetooth communication connection with the bluetooth device, when a plurality of bluetooth devices are directly placed in the bluetooth connection range of the adaptor, the bluetooth device emulator selects the next target bluetooth device to be connected according to the order of the sizes of the identifier numbers of the plurality of new bluetooth devices. Therefore, the Bluetooth device simulator can accurately and automatically connect the next Bluetooth device, otherwise, the old Bluetooth device is disconnected, and the old Bluetooth device is possibly connected when the Bluetooth device is reconnected. Specifically, the unique identifier may be a serial number, and according to a serial number rule, a serial number of a next bluetooth device may be obtained from serial numbers of a batch of bluetooth devices with consecutive serial numbers according to a serial number of a current bluetooth device, where the first serial number may be a serial number of a bluetooth device to which a host issues a command configuration, or may be a serial number of a bluetooth device to which a first connection is set when the host is powered on.
In addition, since the implementation manners of step S201 to step S205 in this embodiment are completely the same as the implementation manners of step S101 to step S105 in the previous embodiment, detailed descriptions thereof are omitted here.
Therefore, it can be seen that the working method of the bluetooth device simulator provided by this embodiment can also enable the bluetooth device simulator to simulate the functions of "pulling out" and "plugging in" the bluetooth device to the host through the USB interface by means of USB soft disconnection and USB soft connection, and for the host, the effect of the simulation method is substantially the same as that of directly plugging in and pulling out the bluetooth device to the host through the USB interface, so that the host working software can work without modification or minimal modification, the upgrade cost is low, and the system stability and compatibility of the host are not affected basically; in addition, the invention also realizes the automatic switching of the Bluetooth equipment and improves the mass production efficiency.
