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 present application. It will be apparent, however, to one skilled in the art that the present application 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 application with unnecessary detail.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It should also be understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
Furthermore, in the description of the present application and the appended claims, the terms "first," "second," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise.
The first embodiment is as follows:
currently, the bluetooth serial number of the application device is usually determined by obtaining an effective serial list before and after the terminal device performs bluetooth pairing. However, when the serial port is not normally closed, the serial port number corresponding to the serial port still exists in the valid serial port list of the terminal device, and the serial port number corresponding to the serial port is actually an invalid serial port number, so that the serial port number of the bluetooth-to-serial port cannot be accurately determined by the serial port numbers in the valid serial port lists before and after bluetooth pairing.
In order to solve the above technical problem, an embodiment of the present application provides a communication method, which is applied to a terminal device, such as a PC (personal computer). In the method, after the terminal device and the application device are successfully paired, the Bluetooth address of the application device is obtained, the corresponding friendly name is obtained according to the Bluetooth address of the application device, the corresponding serial port number is determined according to the friendly name, and finally the terminal device and the application device communicate according to the determined serial port number. The friendly name corresponds to the Bluetooth address and the serial port number of the application device respectively, so that the serial port number determined according to the method is the serial port number corresponding to the Bluetooth address of the application device, namely, the serial port number of the application device at the terminal device can be accurately determined through the method, and therefore the terminal device can be ensured to be in Bluetooth communication with the application device through the determined serial port number successfully.
The following describes a communication method provided in an embodiment of the present application with reference to the drawings.
Fig. 1 shows a flowchart of a communication method provided in an embodiment of the present application, which is applied to a terminal device, where the terminal device may be a PC, and the following details are described as follows:
and step S11, acquiring the Bluetooth address of the application equipment successfully paired with the terminal equipment.
In this embodiment, after the PC is successfully paired with the application device by using the bluetooth name of the application device, the bluetooth address of the application device may be obtained.
In some embodiments, the PC may obtain a Bluetooth Address (BT _ Address) of the application device through a microsoft Bluetooth device-like communication interface.
And step S12, searching the corresponding friendly name according to the Bluetooth address of the application device. The friendly name is one of device information of an application device on a PC, and includes a lot of hardware information of the application device.
In this embodiment, the friendly name of the application device is obtained by setting the parameter of the microsoft PC driver function to a specified value. For example, the parameters of the drive function, setupsigetdeviceregistratiyperproperty, are set to SPDRP _ FRIENDLYNAME for acquisition.
And step S13, determining the serial port number of the application device on the terminal device according to the friendly name.
In this embodiment, the corresponding serial number is obtained by analyzing the value of the friendly name.
And step S14, communicating with the application device according to the serial port number of the application device in the terminal device.
In this embodiment, the PC performs bluetooth communication with the application device according to the determined serial number.
In the embodiment of the application, the friendly names respectively correspond to the bluetooth address and the serial port number of the application device, so the serial port number determined according to the method is the serial port number corresponding to the bluetooth address of the application device, but not the serial port numbers corresponding to other application devices. That is, the serial port number of the application device at the terminal device can be accurately determined by the method, so that the terminal device can successfully perform Bluetooth communication with the application device through the determined serial port number. Meanwhile, the friendly name is searched only through the Bluetooth address of the application equipment, and the addresses in the two effective serial port lists are not required to be matched, so that the speed of determining the serial port number can be increased, and the starting time of the diagnosis application program software installed on the terminal equipment is prolonged.
Example two:
fig. 2 shows a schematic flowchart of another communication method provided in this embodiment, and in this embodiment, the step S12 is mainly detailed, and the step S21, the step S25, and the step S26 are respectively the same as the step S11, the step S13, and the step S14, and are not described again here.
And step S21, acquiring the Bluetooth address of the application equipment successfully paired with the terminal equipment.
Step S22, determining all the device information currently used by the terminal device.
In this embodiment, all the device information currently used by the terminal device may be at least one of the following: plug and Play (PNP), Small Computer System Interface (SCSI), Universal Serial Bus (USB), bluetooth, and other communication device information.
In some embodiments, a microsoft PC driver function (e.g., setupigeretdeviceinfililist) may be used to create a device information block list for the current PC, and a microsoft PC driver function (e.g., setupigegtclassdevexex) may be used to add the requested device information to the created device information block list, such that the device information block list contains device information for all devices currently in use in the current PC.
Step S23, determining target device information in the all device information according to the bluetooth address of the application device, where the target device information is device information of the application device in the terminal device.
In this embodiment, if one of the pieces of device information includes the bluetooth address of the application device, it is indicated that the piece of device information is device information of the application device in the PC, that is, target device information.
Step S24, finding the friendly name in the target device information.
In this embodiment, the friendly name in the target device information is obtained by setting the parameter of the microsoft PC driver function to a specified value.
And step S25, determining the serial port number of the application device on the terminal device according to the friendly name.
And step S26, communicating with the application device according to the serial port number of the application device in the terminal device.
In the embodiment of the application, the target address is the same address as the bluetooth address of the application device in all the device information being used by the terminal device, so that the device information of the application device can be determined as one device information being used by the terminal device as long as the terminal device can determine the target address, and the device information being used by the terminal device corresponds to the friendly name, so that the friendly name corresponding to the bluetooth address of the application device can be found subsequently.
In some embodiments, the step S23 includes:
and A1, selecting one piece of unselected device information from all the device information, and if the currently selected device information contains a character string used for indicating that the device is a Bluetooth device, extracting the target address of the corresponding device from the currently selected device information.
Wherein a string of "bthennum" may be employed to indicate whether a device is a bluetooth device.
In this embodiment, the device information may be arranged first, the device information may be selected one by one according to a sequence from the front to the back, and the target address of the device corresponding to the device information may be extracted from the selected device information. Of course, the device information may be selected one by one in a back-to-front order, as long as it is ensured that the selected device information is not selected.
And A2, if the extracted target address of the device is the same as the Bluetooth address of the application device, determining that the currently selected device information is the target device information.
A3, if the currently selected device information does not contain a character string for indicating that the device is a bluetooth device, or the target address is not the same as the bluetooth address of the application device, returning to the step of selecting an unselected device information from all the device information and the subsequent steps until the target device information is determined, or until all the device information is selected.
In the above-mentioned a1 to A3, the device information may be a value of a device instance path, and at this time, a microsoft PC driver function (e.g., setupigegtdevice instance id) may be used to obtain a value of the device instance path, and determine whether the value of the "device instance path" includes a character string "BTHENUM", and if so, the device is a bluetooth device; otherwise, indicating that the device is not a bluetooth device, return to step a 1. For example: assuming that "bthenun" indicates that the corresponding device is a bluetooth device, as shown in fig. 3, if the value of the obtained device instance path is "bthenun \ 00001101-.
In the above-mentioned a 1-A3, because what needs to obtain is the serial number of the bluetooth to serial port of the application device at the terminal device, therefore, after judging that a device is a bluetooth device, just extract the address of the bluetooth device, can avoid extracting the address of the non-bluetooth device, thereby can improve the speed of determining the target address.
In some embodiments, the extracting the target address of the corresponding device from the currently selected device information in the step a1 includes:
and A11, searching the character which is the same as the preset first character from the currently selected device information, and searching the character which is the same as the preset second character.
The first character and the second character are different characters. As shown in fig. 4, the first character may be set to "&" and the second character may be set to "_". The address between these two characters is denoted as a specific bluetooth address. For example: the device instance path is BTHENUM \ 00001101-.
And A12, taking a character string between the character which is the same as the preset first character and the character which is the same as the preset second character as the target address of the equipment to be extracted.
In this embodiment, a first character and a second character are set in advance, and a character string corresponding to a target address of a device is between the first character and the second character. Therefore, when the target address of the equipment needs to be extracted, the target address of the equipment can be extracted by directly searching the character which is the same as the preset first character and searching the character which is the same as the preset second character, and therefore the required target address of the equipment can be extracted quickly and accurately. In some embodiments, the character string between the character identical to the preset first character and the character identical to the preset second character does not include the character identical to the preset first character and does not include the character identical to the preset second character.
In this embodiment, it is considered that there may be a plurality of first characters and/or a plurality of second characters in the value of the device information, and therefore, only the character string between two adjacent first characters and second characters is extracted, and the accuracy of the extracted target address of the device can be further ensured. Referring to fig. 4, only a character string between the marked "&" and the marked "_" is extracted as a target address of the device.
In some embodiments, the step S25 (or step S13) includes:
and B1, resolving the friendly names to obtain corresponding resolution results.
B2, if the analysis result includes the designated character string, determining the designated character string and all characters following the designated character string as the serial number of the application device in the terminal device.
The specified character string may be a character string including COM.
In this embodiment, whether the analysis result includes a COM string is queried, and a COMXX string is obtained. Referring to fig. 5, assuming that the analysis result of the friendly name is "standard serial over bluetooth link (COM3)", since the analysis result includes a COM character string, "COM" and all characters "3" following the "COM" are set as the serial number of the application device in the terminal device.
In some embodiments, if the COM string is not contained in the parsing result, the procedure returns to step a1 to continue checking the next device.
In some embodiments, after the step S25 (or step S13) above, the method includes:
and storing the serial port number into a configuration file.
In this embodiment, because the serial number is maintained in the configuration file, when the subsequent terminal device communicates with the application device, the corresponding serial number can be directly read from the configuration file, thereby improving the efficiency of communication between the terminal device and the application device.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
