As shown in fig. 1, the system architecture 100 according to this embodiment may include a server 101, a terminal device 102, a bluetooth device 103, and a network 104. The network 104 serves as a medium for providing a communication link between the server 101 and the terminal apparatus 102. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The terminal device 102 and the bluetooth device 103 may communicate via BLE.

A user may use a terminal device 102 to interact with the server 101 over the network 104 to receive or send messages or the like. The server 101 may be a server that provides an upgrade service of the bluetooth device 103. The terminal device 102 may have a communication client application installed thereon, and may download upgrade data for upgrading the bluetooth device 103 from the server 101.

Terminal device 102 may be a variety of electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablets, laptop portable computers, desktop computers, and the like.

It should be noted that the device upgrade method provided by the embodiment of the present disclosure may be generally executed by the terminal device 102 or the bluetooth device 103. Accordingly, the device upgrading apparatus provided by the embodiment of the present disclosure may be generally disposed in the terminal device 102 or the bluetooth device 103.

It should be understood that the number of terminal devices, bluetooth devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, bluetooth devices, networks, and servers, as desired for implementation.

According to the embodiment of the disclosure, the terminal device can obtain upgrade data for upgrading the Bluetooth device from the server, and the method of the embodiment of the disclosure is used for interaction between the terminal device and the Bluetooth device to complete upgrading of the Bluetooth device. The first device described in the methods of fig. 2, 3A to 3C, 4, 5A and 5B below may be implemented, for example, as the terminal device described above, and the second device may be implemented, for example, as the bluetooth device described above. The methods described below in fig. 2, 3A-3C, 4, 5A, and 5B may be implemented as a communication protocol that may be adapted for upgrading of various bluetooth devices.

Fig. 2 schematically shows a flow chart of a device upgrade method according to an embodiment of the present disclosure.

As shown in fig. 2, the method is applied to a first device, and includes operations S210 to S260.

In operation S210, a bluetooth low energy based connection is established with a second device.

In operation S220, device version information of the second device is obtained.

In operation S230, upgrade data is determined based on the device version information of the second device, the upgrade data including at least one upgrade file.

In operation S240, upgrade capability information of the second device is obtained, where the upgrade capability information includes information describing whether or not the upgrade of the second device needs to be restarted.

In operation S250, if the upgrade capability information indicates that the upgrade of the second device needs to be restarted, controlling the second device to be restarted, and scanning the second device until the connection is reestablished with the second device.

In operation S260, the at least one upgrade file is transmitted to the second device.

According to the embodiment of the disclosure, the first device determines the required upgrade data according to the device version information of the second device, the first device may prepare a plurality of upgrade data in advance, determine one upgrade data from the plurality of upgrade data after obtaining the device version information, or obtain the required upgrade data from the server after obtaining the device version information.

The upgrade data may be stored in the server side in the form of a compressed OTA file, for example, and the developer may optionally compress one or more upgrade files into one compression package according to the requirement. In the compressed package, an instruction file may be stored, for example, in the form of json (JavaScript Object notification), in which an upgrade file description is described, including an upgrade address, an upgrade file name, a check value, and the like of the file.

Because the bluetooth chips manufactured by different manufacturers are different, equipment comprising certain bluetooth chips can be upgraded only by restarting, for example, the equipment enters a bootloader program after being restarted, and equipment comprising other bluetooth chips can be upgraded without restarting. The method of the embodiment of the disclosure comprises the following steps: obtaining upgrading capability information of the second equipment, and directly transmitting upgrading data under the condition of not needing to be restarted; and under the condition that the second equipment needs to be restarted, controlling the second equipment to be restarted, reestablishing connection with the second equipment after the second equipment is restarted, and starting to transmit the upgrading data after the second equipment is reconnected. Therefore, the method of the embodiment of the disclosure can adapt to equipment upgrading of various hardware, and improves the compatibility of the protocol.

The method provided by the embodiment of the disclosure supports full scale upgrade and delta scale upgrade. When the upgrade data includes only one upgrade file, the upgrade file is used to replace the original version data as a whole, i.e., full upgrade. When the upgrade data includes a plurality of upgrade files, the upgrade files may be selectively upgraded, i.e., delta upgraded, according to the condition of the second device.

Delta upgrades in embodiments of the present disclosure are described below in conjunction with FIG. 3A.

Fig. 3A schematically illustrates a flow chart of transmitting the at least one upgrade file to the second device according to an embodiment of the present disclosure.

As shown in fig. 3A, the method includes operations S311 to S313.

In operation S311, file identification information of a first upgrade file is transmitted to the second device, where the first upgrade file is used to upgrade a first module to a first version.

In operation S312, feedback information sent by the second device is received, where the feedback information includes information about whether a current version of the first module in the second device is lower than the first version.

In operation S313, if the feedback information indicates that the current version of the first module in the second device is lower than the first version, the first upgrade file is transmitted.

According to the embodiment of the disclosure, when a plurality of upgrade files exist, the judgment can be performed one by one. For example, file identification information of the first upgrade file may be sent to the second device, asking the second device to return feedback information. The first upgrading file is used for upgrading the first module in the second equipment, and the second equipment is required to feed back whether the first upgrading file can be used for upgrading the current first module. For example, the first upgrade file is used to upgrade the first module to a first version, and if the current version of the first module in the second device is a second version lower than the first version, the first upgrade file can be used to upgrade the first module in the second device to start transmitting the first upgrade file. If the current version of the first module in the second device is the first version or a third version higher than the first version, the first upgrade file cannot be used for upgrading the first module in the second device. At this time, the first upgrade file is not transmitted any more, but the next upgrade file is searched for a similar judgment.

Under the condition that the data volume of the upgrade file is too large, if the verification is not needed to be retransmitted after the upgrade, a large amount of time is wasted. In order to solve the problem, the method of the embodiment of the present disclosure further provides a method for checking in segments in the process of transmitting the upgrade file, so that once the situation that the check fails occurs, the whole file does not need to be retransmitted.

Fig. 3B schematically illustrates a flow chart of transmitting the at least one upgrade file to the second device according to an embodiment of the present disclosure.

As shown in fig. 3B, the method includes operations S321 and S322.

Dividing the upgrade file into a plurality of parts, calculating a check value of each of the plurality of parts,

in operation S322, the plurality of parts and the check value of each of the plurality of parts are transmitted to the second device.

According to the embodiment of the present disclosure, for example, a segment may be made every 4K, the check value of the segment is calculated, when a segment is transmitted, the check value of the segment is also transmitted, and the second device may perform a check according to the check value to determine whether the segment is correctly transmitted, and no data loss occurs. The checking method may be, for example, Cyclic Redundancy Check (CRC).

During the upgrade process, the situation that the upgrade is terminated due to abnormal disconnection may occur. To solve this problem, the method of the embodiment of the present disclosure adopts a breakpoint resuming method to avoid repeated transmission of data.

Fig. 3C schematically illustrates a flowchart of transmitting the at least one upgrade file to the second device according to an embodiment of the present disclosure.

As shown in fig. 3C, the method may further include operations S331 to S333 based on the foregoing embodiment.

In operation S331, if the connection with the second device is interrupted during the transmission of the at least one upgrade file, the effective data length received by the second device is acquired after the reconnection.

In operation S332, a retransmission position is determined based on the valid data length.

In operation S333, the at least one upgrade file is continuously transmitted from the resume location.

According to an embodiment of the present disclosure, after reconnection, the second device sends the received effective data length to the first device. After the first device obtains the effective data length, the continuous transmission position can be determined according to the effective data length, and the upgrade file is continuously transmitted from the continuous transmission position, so that repeated data transmission is avoided.

After the upgrade data is transmitted and received, the first device sends notification information to the second device to notify the second device that the upgrade data is transmitted, the second device can selectively carry the upgrade data to the application area according to the characteristics of the second device, and then returns the upgrade completion message, or directly returns the upgrade completion message to notify the first device that the upgrade is completed.

Accordingly, fig. 4, 5A and 5B schematically illustrate a device upgrade method applied to a second device according to an embodiment of the present disclosure.

Fig. 4 schematically shows a flow chart of a device upgrade method according to another embodiment of the present disclosure.

As shown in fig. 4, the method is applied to the second device, including operations S410 to S450.

In operation S410, a bluetooth low energy based connection is established with a first device.

In operation S420, device version information of the second device is transmitted to the first device.

In operation S430, upgrade capability information of the second device is transmitted to the first device. The upgrade capability information includes information describing whether or not the upgrade of the second device needs to be restarted.

In operation S440, if the upgrade of the second device needs to be restarted, the second device is restarted, and a connection is reestablished with the first device after the restart.

In operation S450, at least one upgrade file transmitted by the first device is received.

Fig. 5A schematically illustrates a flowchart of receiving at least one upgrade file transmitted by the first device according to an embodiment of the present disclosure.

As shown in fig. 5A, the method includes operations S511 to S513.

In operation S511, file identification information of a first upgrade file is received, where the first upgrade file is used to upgrade a first module to a first version.

In operation S512, it is determined whether the current version of the first module is lower than the first version, so as to obtain feedback information.

In operation S513, the feedback information is transmitted to the first device.

Fig. 5B schematically illustrates a flowchart of receiving at least one upgrade file transmitted by the first device according to an embodiment of the present disclosure.

As shown in fig. 5B, the method includes operations S521 to S523.

In operation S521, a first portion of the upgrade file and a check value of the first portion are received.

In operation S522, the first part is verified based on the verification value, and a verification result is obtained.

In operation S523, in case that the check result indicates that the transmission of the first portion is incomplete, the first apparatus is notified to retransmit the first portion.

According to the embodiment of the present disclosure, the method further includes sending the received valid data length to the first device after reconnection if the connection with the first device is interrupted during the transmission of the at least one upgrade file.
