Detailed implementation manners

[0020] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system architectures, technologies, etc. are presented in order to provide a thorough understanding of the embodiments of the present application. However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from hindering the description of the present application.

[0021] In order to illustrate the technical solutions described in the present application, the following will be described through specific embodiments.

[0022] With the progress of technology, Bluetooth technology plays an increasingly important role in the field of wireless communication. It is known for its simplicity, allowing devices to conveniently transfer files as long as they are within a suitable distance from each other without network support. However, Bluetooth transmission also faces challenges in some cases. For example, when the devices are far apart or the signal quality is poor, the transmission may be interrupted.

[0023] For example, when a user attempts to update the firmware of a certain device using Bluetooth technology through a mobile phone application, if the transmission is aborted due to unstable signal or insufficient battery power of the mobile phone, the user will have to re - establish the connection and start the transmission from the beginning. This not only prolongs the data transmission time but also reduces the transmission efficiency.

[0024] Therefore, the embodiments of the present application propose a data breakpoint transmission method, as Figure 1 shown in the schematic diagram of the implementation scenario of this method. In the implementation scenario of data breakpoint transmission, it includes a data breakpoint transmission device 1 and a data receiving device 2.

[0025] Among them, the data breakpoint transmission device 1 can include intelligent devices such as mobile phones, tablets, servers, etc. The data receiving device can include devices such as inverters or other embedded devices that need to perform firmware upgrades. The data transmission link between the data breakpoint transmission device 1 and the data receiving device 2 can include, for example, a Bluetooth link, a Wifi link, etc.

[0026] The data breakpoint transmission device 1 includes data to be transmitted 10 and a record file 11. The data to be transmitted can be divided into at least two arrays according to the data group capacity, and each array corresponds to a mapping identifier. In the record file 11, the data to be transmitted with the added mapping identifier can be written. When the data breakpoint transmission device 1 sends the data to be transmitted to the data receiving device 2, when the data receiving device 2 receives an array including the mapping identifier, it will send a response message to the data breakpoint transmission device 1. The data breakpoint transmission device 1 updates the breakpoint identifier in the record file 11 according to the mapping identifier included in the response message. After the transmission of the data to be transmitted is interrupted, the array with the breakpoint identifier as the mapping identifier can be found according to the breakpoint identifier in the record file 11, so that the data to be continued to be transmitted can be sent reliably and effectively, improving the efficiency and reliability of data transmission.

[0027] Figure 2 FIG. 4 is a schematic flowchart of an implementation of a data breakpoint transmission method provided by an embodiment of the present application, which is described in detail as follows: In S201, the data to be transmitted is obtained.

[0028] The data to be transmitted in the embodiment of the present application may include, for example, firmware upgrade data, parameter configuration data, etc.

[0029] The data to be transmitted in the embodiment of the present application may be data in the BIN file format for firmware upgrade. The BIN file is in binary format and can directly contain the original data of the firmware without going through compression or encoding processing, thereby effectively improving the accuracy and integrity of the firmware file during transmission and writing.

[0030] When obtaining the data to be transmitted, the data identification information of the data to be transmitted can be obtained. For example, when the data to be transmitted is a BIN file for firmware upgrade, since the BIN file is used for firmware upgrade, the version information of the BIN file upgrade can be used as the data identification information. By using the version information of the data to be transmitted as the data identification information, different versions of firmware upgrade data can be effectively distinguished, which is beneficial to improving the identification degree of the data to be transmitted.

[0031] In S202, a cache of a mapping set is created according to the data to be transmitted, and the mapping set includes the mapping identifier of the data to be transmitted and the array corresponding to the mapping identifier.

[0032] Wherein, the array is generated according to the data to be transmitted.

[0033] In order to facilitate the resumption of transmission of the data to be transmitted, in the embodiment of the present application, the data to be transmitted can be sequentially segmented according to a predetermined array capacity to obtain at least two arrays formed by dividing the data to be transmitted. Among them, the array capacity is smaller than the capacity of the data to be transmitted.

[0034] For at least two arrays obtained by partitioning, mapping identifiers can be added to the arrays according to the order of the arrays in the data to be transmitted. The mapping identifier is the identifier mapped to the array. The position of the array can be quickly located according to the mapping identifier.

[0035] For example Figure 3 As shown in the figure, assume that the size of the BIN file of the data to be transmitted is 10,000 bytes, and the capacity of a single array is 1,000 bytes. For the data to be transmitted, it can be read starting from the first byte. After reading 1,000 bytes, the first array, i.e., array 1, is obtained. It can be set that array 1 corresponds to the mapping identifier 1. Then, starting from the 1,001st byte, after reading 1,000 bytes, the second array, i.e., array 2, is obtained. It can be set that array 2 corresponds to the mapping identifier 2. Read sequentially backward according to this method until the last byte of the data to be transmitted, such as the 10,000th byte of the data to be transmitted, and set the last array, i.e., array 10, to correspond to the mapping identifier 10. According to the established correspondence between the arrays and the mapping identifiers, a mapping set is obtained, that is, a set of arrays and mapping identifiers.

[0036] The mapping set in the embodiment of the present application can be stored in the cache in the form of key-value pairs. For example, for the mapping identifier 0, it can be used as the key, and the data from the 1st byte to the 1,000th byte corresponding to the mapping identifier 0 is used as the value. The correspondence between the mapping identifier and the array is cached in the form of key-value. For the correspondence between other mapping identifiers and arrays, it can also be cached in the form of key-value. Caching the correspondence between the mapping identifier and the array in the form of key-value pairs enables quick access to the array through the key, which is beneficial to improving the data access efficiency.

[0037] In S203, a record file is created according to the data to be transmitted, a breakpoint identifier is set in the record file, and the mapping set is written into the record file.

[0038] To facilitate recording the current sending progress, a record file can be created according to the data to be transmitted in the embodiment of the present application. The name of the record file can include the version information of the data to be transmitted. For example, the version information of the file to be transmitted can be directly used as the name of the record file, thereby establishing the relationship between the record file and the data to be transmitted. Without limitation, the relationship between the record file and the data to be transmitted can also be established according to other identification information of the file to be transmitted, including, for example, the summary information of the file to be transmitted. For example, the summary information of the file to be transmitted can be directly used as the name of the record file.

[0039] The record file in the embodiments of the present application is used to record mapping identifiers and arrays. The position of the array in the record file and the position of the mapping identifier in the record file can be determined according to the preset array capacity size. The record file can be a file in TXT text format, etc. As Figure 4 shown, when the mapping identifier occupies one byte and the length of the array is m bytes, if the position of the first mapping identifier is the a-th byte (a is a natural number, and the first a bytes can be set as breakpoint identifiers), then the position of the n-th mapping identifier is the (a + (m + 1) * (n - 1))-th byte, and the position of the first character of the array corresponding to the n-th mapping identifier is a + 1 + (m + 1) * (n - 1).

[0040] The record file in the embodiments of the present application includes breakpoint identifiers (TAGs), and the breakpoint identifier can be the latest identifier of the array that has been successfully sent. Due to different data sending protocols, the number of breakpoint identifiers can include one or at least two.

[0041] For example, when the array sending protocol is the stop-and-wait protocol, one breakpoint identifier can be set. When the array sending protocol is the sliding window protocol, the number of breakpoint identifiers can be determined according to the number of arrays included in the sliding window. For example, when the number of arrays in the sliding window protocol is 3, the number of breakpoint identifiers can be set to 3, which are respectively used to record the sending status of the 3 arrays in the sliding window.

[0042] In S204, send the array of the data to be transmitted, and update the breakpoint identifier in the record file according to the response message indicating successful sending.

[0043] When sending data, data blocks can be generated according to the arrays. A data block can include a single array and the mapping identifier corresponding to the array. When sending data, the data blocks can be sent in order according to the order of the mapping identifiers.

[0044] After the data block is sent to the data receiving device, the data receiving device will return a response message. The response message includes the mapping identifier of the array and an identifier indicating whether the reception is successful. When it is detected that the data block corresponding to the mapping identifier has been successfully received, the mapping identifier can be updated in the breakpoint identifier in the record file, indicating that the array corresponding to the mapping identifier has been successfully sent and received.

[0045] The sending methods of the data to be transmitted in the embodiments of the present application can include the stop-and-wait protocol and the sliding window protocol. Among them, the stop-and-wait protocol is to send one data block each time until the data is successfully received, that is, after receiving the response message indicating successful sending, update the breakpoint identifier to the mapping identifier of the data block, and send the next data block.

[0046] For example, the initialized breakpoint identifier is 0. After sending the first data block, if a response message indicating successful transmission is received, the breakpoint identifier can be updated to the mapping identifier of the first data block, indicating that the first data block has been successfully sent. If a data interruption occurs at this time, based on the current breakpoint identifier, the first data block can be searched backward from the breakpoint identifier, and the second data block is determined as the data block to be continuously transmitted.

[0047] The number of data blocks sent each time in the sliding window protocol is the number of data blocks included in the sliding window. If there are 3 data blocks included in the sliding window, 3 breakpoint identifiers can be set. After the data block with the smallest mapping identifier in the currently sent 3 data blocks is successfully received, the sliding window is slid backward. The step size of the sliding window is determined according to the smallest mapping identifier of the data blocks that have not been successfully sent in the current sliding window, so that the data blocks sent in the sliding window start from the smallest mapping identifier, and the newly sent data blocks are determined according to the sliding window length.

[0048] For example Figure 5 As shown, the data blocks sent in parallel for the first time are 1, 2, and 3. If response messages indicating successful transmission of data blocks 1, 2, and 3 are received, the breakpoint identifiers initialized to 0 are updated to 1, 2, and 3 respectively, and the sliding window is slid backward by 3 steps to send data blocks 4, 5, and 6. If only a response message indicating successful transmission of data block 1 is received after sending data blocks 1, 2, and 3, then one of the breakpoint identifiers is updated to 1, and the other two breakpoint identifiers remain 0. At this time, the smallest mapping identifier of the data blocks that have not been successfully sent is 2. Starting from 2 and with a window length of 3, data blocks 2, 3, and 4 are determined as the currently being sent data blocks. When a response message indicating successful transmission of data block 2, 3, or 4 is received, the smallest identifier in the breakpoint identifiers is updated to the currently successful response identifier. For example, after data blocks 2 and 3 are successfully sent, the two breakpoint identifiers with a value of 0 in the breakpoint identifiers are updated to 2 and 3 respectively. At this time, the smallest mapping identifier of the data blocks that have not been successfully sent is 4, so data blocks 4, 5, and 6 are determined as the currently sent data blocks. If the transmission is successful, for example, data block 5 is successfully sent, then the smallest breakpoint identifier 1 is updated to 5, and it is determined that the mapping identifier of the data blocks that have not been successfully sent is still 4. At this time, the currently sent data blocks are not updated temporarily. At this time, if the transmission is interrupted, based on the 2, 3, and 5 recorded in the breakpoint identifiers, the smallest mapping identifier of the data blocks that have not been successfully sent can be determined. The first missing identifier found in the increasing direction starting from the smallest identifier of the breakpoint identifiers is the mapping identifier to be continuously transmitted. For example, if the breakpoint identifiers only record 2, 3, and 5, and the first missing consecutive identifier is 4, then the array corresponding to the mapping identifier 4 is determined as the data to be continuously transmitted.

[0049] In S205, after the interruption of the transmission of the data to be transmitted, according to the breakpoint identifier in the record file, find the corresponding mapping identifier in the mapping set in the record file, and find and transmit the data to be continued according to the mapping identifier.

[0050] According to the response message after the data block is sent, the value of the breakpoint identifier can be updated in real time, and the mapping identifier corresponding to the latest successfully sent data block is updated to the breakpoint identifier. If the transmission is interrupted, the data to be continued can be determined according to the breakpoint identifier, and the breakpoint resume transmission can be performed according to the determined data to be continued, so as to reduce the probability of data duplicate transmission and improve the data transmission efficiency.

[0051] In addition, in the embodiment of the present application, when it is determined that the transmission of the data to be transmitted is interrupted, if the response message indicating successful reception is not received within a specified duration, the transmission can be repeated a specified number of times, for example, three times can be repeated. If the response is still not successful after repeating the specified number of times, it can be determined that the transmission of the data to be transmitted is interrupted, and the data to be continued can be determined according to the breakpoint identifier saved in the record file.

[0052] In addition, after the data to be continued is determined according to the mapping identifier in the embodiment of the present application, if the reconnection is successful, the cache can be searched first to determine whether the data can be paired by key (key) - value (value) in the cache, and the array corresponding to the mapping identifier of the data to be continued is searched. If so, the data block generated by the array in the cache is directly used for resume transmission. If the array corresponding to the mapping identifier of the data to be continued cannot be found in the cached data, the mapping identifier and the array in the record file, and the key - value pair data of the cached mapping identifier and the array can be cached, so that the data to be continued can be quickly located in the key - value pair cache according to the breakpoint identifier.

[0053] When all the data to be transmitted is successfully transmitted, the record file can be deleted, such as deleting the text file including the breakpoint identifier and the mapping set, etc., so as to release the storage space.

[0054] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution is prior or posterior. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
