Detailed Description
The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
In order to further explain the data transmission method, the device upgrading method and the computer readable storage medium in the embodiments of the present invention, the application scenarios of the data transmission method, the device upgrading method and the computer readable storage medium in the embodiments of the present invention are further described below.
The first device in the embodiment of the present invention may be a mobile phone terminal with a bluetooth transmission function, a tablet terminal, or other terminal devices with a bluetooth transmission function and used for managing or controlling the second devices, which is not limited in this aspect of the present invention, and the first device may be used for performing a corresponding control operation on one or more second devices, for example, upgrading the second devices. The second device in the embodiment of the present invention, that is, the foregoing bluetooth device, may specifically be an internet of things device having a bluetooth transmission function, for example, an intelligent sound box, an intelligent television, an intelligent refrigerator, an intelligent washing machine, an intelligent toothbrush, or other terminal devices that can be controlled by the first device, which is not limited in this invention.
Fig. 2 is a schematic diagram of a scenario of upgrading a bluetooth device according to an embodiment of the present invention, as shown in fig. 2, a first device in an embodiment of the present invention may download or store a corresponding second device upgrade package from a server in advance, or download the second device upgrade package from the server in real time during an upgrade process, and send the second device upgrade package to the second device for the second device to upgrade through bluetooth transmission.
In an exemplary embodiment, the second device is a smart speaker and the first device is a cell phone equipped with an APP for controlling the smart speaker. After a user inquires that the intelligent sound box can be upgraded through the intelligent sound box control APP on the first device, the upgrade package is downloaded to the mobile phone from the server through wireless communication or WiFi, and after Bluetooth connection is established between the mobile phone and the intelligent sound box, the upgrade package is split into a plurality of fragments to be sequentially transmitted to the intelligent sound box for the intelligent sound box to upgrade.
The data transmission method, the device upgrade method, and the computer-readable storage medium in the embodiments of the present invention are described in detail below.
Example 1
The present embodiment provides a data transmission method, applied to a first device, and fig. 3 is a flowchart (a) of the data transmission method provided according to an embodiment of the present invention, as shown in fig. 3, where the data transmission method in the present embodiment includes:
s102, the first device sends a plurality of first data packets to the second device according to the user instruction.
It should be further noted that, the plurality of first data packets are segments of an upgrade packet obtained by the first device, and the plurality of first data packets are part of segments of the upgrade packet, for example, for an upgrade packet with a size of 102.4KB, the plurality of first data packets may be split into 200 segments with a size of 512B, and each segment is a data packet in this embodiment. In the step S102, the first device may select a plurality of fragments, such as 20 fragments, from the 200 fragments, and send the plurality of fragments as the first data packet to the second device.
It should be further noted that, in step S102, the first device may send the plurality of first data packets sequentially. Similarly, in step S106 described below, the first device transmits a plurality of second data packets sequentially.
S104, the first device sends a query message to the second device to query the second device for the first data packet failed to receive.
In an optional embodiment, in step S104, sending the query message to the second device includes:
sending a query message to the second device to instruct the second device to return a confirmation message according to the query message; the acknowledgement message is used for indicating the second device to receive the failed first data packet.
It should be further noted that, in this embodiment, an identifier may be allocated to each segment during splitting the upgrade package into several segments, for example, each segment is identified by a segment sequence number. In the above optional embodiment, after receiving the query information sent by the first device, the second device may query the first data packet that fails to be received by itself, and generate a confirmation message to return to the first device.
Specifically, the confirmation message may carry an identifier of the first data packet that the second device receives successfully, so that after the first device receives the confirmation message, the first data packet that the second device receives successfully can be determined by a screening manner; alternatively, the second device may directly carry the identifier of the first data packet that fails to be received in the acknowledgement message, which is not limited in the present invention.
S106, the first device sends a second data packet to the second device, wherein the second data packet comprises at least one of the following: the second equipment receives the failed first data packet and the data packet to be sent; alternatively, the transmission operation is stopped.
It should be further noted that, in the step S106, the second data packet may be determined according to different scenes. In an example, in a case where there is a data packet to be transmitted, and the query information indicates that there is a first data packet that the second device fails to receive, the second data packet includes the data packet to be transmitted, and the first data packet that fails to receive. In another example, there is a data packet to be transmitted, and the query information indicates that there is no case of the first data packet failed to be received by the second device, the second data packet including the data packet to be transmitted. In another example, where there is no data packet to be transmitted and the query information indicates that there is a first data packet that the second device failed to receive, the second data packet includes the first data packet that failed to receive. In another example, the transmitting operation is stopped in a case where there is no data packet to be transmitted and the inquiry information indicates that there is no first data packet that the second device fails to receive.
In an optional embodiment, in step S106, the first device sends the second data packet to the second device, including:
selecting a first data packet which fails to be received by a second device from the plurality of first data packets as a second data packet; selecting one or more data packets from a plurality of data packets to be transmitted as second data packets;
the second data packet is sent to the second device.
It should be further noted that in the above alternative embodiment, after the first device learns that the second device fails to receive the first data packet, the first device may retransmit the first data packet to the second device in the next transmission process. For example, the first device still keeps transmitting 20 packets to the second device each time, the first device defines the packets identified as 1 to 20 as the first packet to be transmitted to the second device in step S102, the second device fails to successfully receive the packets identified as 18 and 19 in practice, the first device may define the packets identified as 18 and 19 as the second packet in step S106, and the selected packets identified as 21 to 38 in the packets to be transmitted as the second packet to be transmitted to the second device.
In an alternative embodiment, the number of the first data packets is the same as the number of the second data packets except for the case that the number of the data packets to be transmitted is insufficient, that is, the number of the plurality of data packets transmitted to the second device by the first device at a time is the same.
According to the data transmission method in the embodiment of the invention, after a plurality of first data packets are sent to the second device according to the user instruction, a query message is sent to the second device to query the second device for the first data packet failed to be received, so that the second data packet is sent to the second device, wherein the second data packet comprises at least one of the following components: the second equipment receives the failed first data packet and the data packet to be sent; alternatively, the transmission operation is stopped. Therefore, in the process of transmitting the data packets to the second device for device upgrading, the first device determines which data packets are failed to receive in a query message mode, and the second device does not need to respond to each data packet/upgrading packet segment, so that the response time of the second device is not generated in the process, the transmission efficiency is improved obviously, and unnecessary network resources are prevented from being occupied. Therefore, the invention can solve the problem that in the related technology, the Bluetooth equipment needs to respond to each upgrade package segment in the upgrading process so as to cause overlong upgrading time, thereby achieving the effect of obviously improving the transmission efficiency of the upgrade package in the upgrading process of the Bluetooth equipment.
In addition, the data transmission method in this embodiment can ensure complete transmission of data by actively querying the first device to the second device on the premise of improving transmission efficiency.
In an optional embodiment, in step S102, the sending a plurality of first data packets to the second device according to the user instruction includes: according to a user instruction, N first data packets are sent to second equipment, wherein N is a positive integer; in the step S102, before the N first data packets are sent to the second device according to the user instruction, the method further includes:
determining the value of N according to the volume of the upgrade package, a maximum transmission unit (Maximum Transmission Unit, MTU) preset between the first device and the second device and a preset query period;
the first data packet and the second data packet are fragments of an upgrade packet.
In an optional embodiment, the determining the value of N according to the volume of the upgrade package, the preset maximum transmission unit MTU between the first device and the second device, and the preset query period includes:
determining the transmission times between the first equipment and the second equipment according to the volume of the upgrade package and the MTU between the first equipment and the second equipment, and splitting the upgrade package into a plurality of data packages according to the transmission times;
and determining the value of N according to the number of the data packets and the query period.
It should be further noted that, the file size or the file length of the upgrade package is set as S, and the MTU between the first device and the second device may be negotiated during bluetooth connection, and set as M; the above-mentioned inquiry period can be represented by a preset progress inquiry stage value, that is, the preset inquiry position is located in the percentage of the total transmission progress of the upgrade package, and is set to P, and an inquiry is performed once per P (percentage) of the total transmission progress of the upgrade package. Thus, the above N should satisfy:
N＝(S/M)*P。
for example, the size of the upgrade package is 102.4KB, i.e. s=102.4kb, and the MTU negotiated between the first device and the second device is 512B, so that it can be determined that the first device can transmit a file with a size of 512B to the second device at most at a time, and therefore, the upgrade package needs to be split into 102400/512, i.e. 200 fragments, and each fragment forms a data package. On this basis, a query is made according to the user setting the P to 10%, i.e., 10% of the total transmission progress of the upgrade package per completion.
Thus, the value of N can be determined to be (102400/512) 10%, that is, N is 20, so that it can be determined that the first device sends a query message to the second device to perform a query every time the first device sends 20 data packets to the second device.
To further illustrate the workflow of the data transmission method in the embodiment of the present invention, the following description is given by way of an exemplary embodiment:
example embodiment 1
Fig. 4 is an interaction schematic diagram of a first device and a second device according to an exemplary embodiment of the present invention, where, as shown in fig. 4, the first device is a mobile phone, the second device is a bluetooth device, and a user performs an upgrade operation of the second device through a corresponding APP in the mobile phone. The mobile phone downloads the upgrade package to the local from the server in advance, and establishes Bluetooth connection with the Bluetooth device. The size of the upgrade package is 102.4KB, and the MTU negotiated between the mobile phone and the Bluetooth device is 512B, so that the upgrade package can be split into 200 data packages for sequential transmission. In the upgrading process, the data transmission flow between the mobile phone and the Bluetooth device is as follows:
s1, 20 data packets with the identifiers of 1 to 20 are selected by a mobile phone and sent to Bluetooth equipment one by one;
s2, actively sending a query message to the Bluetooth device by the mobile phone so as to read a data packet which is specifically received successfully by the Bluetooth device from the Bluetooth device;
s3, if the Bluetooth device receives all 20 data packets in the step S2, the mobile phone selects 20 data packets with the identifiers of 21 to 40 again and sends the 20 data packets to the Bluetooth device one by one; if in step S2, the bluetooth device only receives 15 data packets with the identifiers of 1 to 15, the mobile phone selects 20 data packets with the identifiers of 16 to 35 and sends the 20 data packets to the bluetooth device one by one;
s4, repeating the steps S1 to S3 until the data of the upgrade package are completely sent.
