Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements 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 following further explains application scenarios of the data transmission method, the device upgrading method, and the computer-readable storage medium in the embodiments of the present invention.
The first device in the embodiment of the present invention may be a mobile phone terminal, a tablet terminal, or another terminal device that has a bluetooth transmission function and is capable of managing or controlling the second device, and the present invention is not limited to this. The second device in the embodiment of the present invention, that is, the 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 respect.
Fig. 2 is a schematic view of a scenario of bluetooth device upgrade according to an embodiment of the present invention, as shown in fig. 2, a first device in the 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 a second device through bluetooth transmission for upgrading the second device.
In an exemplary embodiment, the second device is a smart speaker, and the first device is a mobile phone installed with an APP for controlling the smart speaker. After the user inquires about the smart sound box through smart sound box control APP on the first equipment and can upgrade, the upgrade package is downloaded to the mobile phone from the server through wireless communication or WiFi, and after the mobile phone is connected with the smart sound box through Bluetooth, the upgrade package is split into a plurality of fragments which are sequentially sent to the smart sound box, so that the smart sound box can be upgraded.
The following describes a data transmission method, an apparatus upgrading method, and a computer-readable storage medium in the embodiments of the present invention in detail.
Example 1
The present embodiment provides a data transmission method applied to a first device, and fig. 3 is a flowchart (one) of a data transmission method provided according to an embodiment of the present invention, as shown in fig. 3, 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 fragments of the upgrade package acquired by the first device, and the plurality of first data packets are partial fragments of the upgrade package, for example, for an upgrade package with a size of 102.4KB, the plurality of first data packets may be split into 200 fragments with a size of 512B, and each fragment is a data packet in this embodiment. In step S102, the first device may select a plurality of segments, for example, 20 segments, from the 200 segments, and send the selected segments as the first data packet to the second device.
It should be further noted that, in step S102, the first device may sequentially transmit the plurality of first data packets. Similarly, in step S106, the first device transmits a plurality of second packets sequentially.
S104, the first device sends an inquiry message to the second device to inquire the second device to receive the failed first data packet.
In an optional embodiment, in step S104, the sending a query message to the second device includes:
sending a query message to the second equipment to indicate the second equipment 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, in the process of splitting the upgrade package into a plurality of fragments, an identifier may be allocated to each fragment, for example, each fragment is identified by a fragment 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 whose reception is failed, 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 is successfully received by the second device, so that after receiving the confirmation message, the first device may determine, in a screening manner, the first data packet that is failed to be received by the second device; alternatively, the second device may also directly carry the identifier of the first data packet with failed reception in the acknowledgement message, which is not limited in this embodiment of 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 failed to receive, the second data packet includes the data packet to be transmitted and the first data packet that failed to receive. In another example, there is a data packet to be transmitted, and the query information indicates that there is no situation where the first data packet failed to be received by the second device, and the second data packet includes the data packet to be transmitted. In another example, in a case 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, in a case where there is no data packet to be transmitted and the query information indicates that there is no first data packet that the second device failed to receive, the transmission operation is stopped.
In an optional embodiment, in step S106, the sending, by the first device, the second data packet to the second device includes:
selecting a first data packet which fails to be received by the 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;
and sending the second data packet to the second device.
It should be further noted that, in the above optional embodiment, after knowing that the second device receives the first data packet that fails, the first device may resend the first data packet to the second device in the next sending process. For example, the first device still keeps sending 20 data packets to the second device each time, then in step S102, the first device defines the data packets identified as 1 to 20 as the first data packet to be sent to the second device, and the second device fails to receive the data packets identified as 18 and 19 successfully, then the first device may define the data packets identified as 18 and 19 as the second data packet in step S106, and at the same time, defines the data packets identified as 21 to 38 selected from the data packets to be sent as the second data packet to be sent to the second device.
In an alternative embodiment, the number of first data packets is the same as the number of second data packets except for the case where the number of data packets to be transmitted is insufficient, i.e. the number of data packets transmitted by the first device to the second device at a time is the same.
By the data transmission method in the embodiment of the present invention, after sending a plurality of first data packets to the second device according to the user instruction, an inquiry message may be sent to the second device to inquire about the first data packet that the second device failed to receive, so as to send a second data packet to the second device, where the second data packet includes at least one of: 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 sending the data packets to the second device by the first device for device upgrading, the first device determines which data packets are failed to be received in a mode of inquiring messages, and the second device does not need to respond to each data packet/upgrading packet fragment, so that the time for responding by the second device is not generated in the process, the transmission efficiency is obviously improved, and unnecessary network resources are avoided being occupied. Therefore, the invention can solve the problem that in the related technology, the upgrading time is too long because each upgrading packet fragment needs to be responded in the upgrading process of the Bluetooth equipment, thereby achieving the effect of remarkably improving the transmission efficiency of the upgrading packet 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 second device by the first device, on the premise of improving the transmission efficiency.
In an optional embodiment, in the step S102, the sending a plurality of first data packets to the second device according to a user instruction includes: sending N first data packets to second equipment according to a user instruction, wherein N is a positive integer; in step S102, before sending the N first data packets 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 (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 the upgrade packet.
In an optional embodiment, the determining the value of N according to the volume of the upgrade package, the maximum transmission unit MTU preset between the first device and the second device, and the preset polling 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 to S, and the MTU between the first device and the second device may perform negotiation during bluetooth connection, and is set to M; the query period may be represented by a preset progress query phase value, that is, the preset percentage of the query position in the total transmission progress of the upgrade package is set as P, and the query is performed once every time P (percentage) of the total transmission progress of the upgrade package is completed. Thus, N should satisfy:
N＝(S/M)*P。
for example, if the size of the upgrade package is 102.4KB, that is, S is 102.4KB, and the MTU negotiated between the first device and the second device is 512B, it may be determined that the first device can transmit a file with a size of 512B to the second device at most each time, and therefore, the upgrade package needs to be split into 102400/512, that is, 200 fragments, each of which constitutes one data package. On the basis, according to the fact that the user sets the P to be 10%, namely, 10% of the total transmission progress of the upgrade package is inquired once.
Thus, it can be determined that N is (102400/512) × 10%, i.e. N is 20, and thus it can be determined that the first device sends an inquiry message to the second device for one inquiry every 20 packets sent 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 made with an exemplary embodiment:
example embodiment 1
Fig. 4 is an interaction diagram of a first device and a second device provided according to an exemplary embodiment of the present invention, and as shown in fig. 4, in the exemplary embodiment, the first device is a mobile phone, the second device is a certain bluetooth device, and a user performs an upgrade operation on the second device through a corresponding APP in the mobile phone. The mobile phone downloads the upgrade package from the server to the local in advance, and establishes Bluetooth connection with the Bluetooth equipment. 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 divided into 200 data packages to be transmitted sequentially. In the upgrading process, the data transmission process between the mobile phone and the Bluetooth device is as follows:
s1, the mobile phone selects 20 data packets with the identifiers of 1 to 20 and sends the data packets to the Bluetooth equipment one by one;
s2, the mobile phone actively issues an inquiry message to the Bluetooth device so as to read the data packet successfully received by the Bluetooth device from the Bluetooth device;
s3, if in step S2, the bluetooth device has received all 20 data packets, the mobile phone selects again 20 data packets labeled 21 to 40 to issue to the bluetooth device one by one; if in step S2, the bluetooth device only receives 15 data packets identified as 1 to 15, the mobile phone selects 20 data packets identified as 16 to 35 and issues the data packets to the bluetooth device one by one;
and S4, repeating the steps S1 to S3 until the upgrade package data is completely transmitted.
