Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In the related art, a computer or a smart phone is connected with a bluetooth terminal to be upgraded via bluetooth to transmit data to the bluetooth terminal and upgrade the bluetooth terminal. Bluetooth connection usually adopts Bluetooth Low Energy (BLE) connection or traditional Bluetooth connection (BT, or Classic Bluetooth connection), wherein Bluetooth low energy is a Bluetooth technology standard developed on the basis of traditional Bluetooth, and Bluetooth after 4.0 is taken as the main point, and the Bluetooth low energy connection is characterized by low cost, low power consumption and strong reliability, and is mostly applied to applications with higher real-time requirement but lower data transmission rate, and during the upgrade process of a Bluetooth terminal, the data volume of upgrade data is usually larger, so the Bluetooth connection mode makes the upgrade of the Bluetooth terminal need more time consumption, and the user experience is poor; the traditional bluetooth is a generic name of bluetooth technology before bluetooth 4.0, and is used for data transmission with large data volume, for example: voice, music, video and other data, but for the upgrade of the bluetooth terminal, the bluetooth technology has no security verification mechanism, so the reliability of data transmission is not high.

In view of one or more of the above-described problems, exemplary embodiments of the present disclosure provide a bluetooth terminal upgrade method. Fig. 1 shows a system architecture diagram of an environment in which the method operates. As shown in fig. 1, the system architecture 100 may include a smart terminal 110 and a bluetooth terminal 120, wherein the smart terminal 110 may be a smart phone, a personal computer, a tablet computer, or the like having a bluetooth connection function; the bluetooth terminal 120 is a terminal device using bluetooth connection as a main interactive mode, and may be a bluetooth headset, an electronic scale, an intelligent bracelet, a bluetooth mouse, and the like; the intelligent terminal 110 may be connected to the bluetooth terminal 120 in a bluetooth manner to perform data transmission.

The following describes the bluetooth terminal upgrading method with the smart terminal 110 and the bluetooth terminal 120 as executing entities.

Fig. 2 shows a flowchart of a bluetooth terminal upgrading method performed by the smart terminal 110, which may include the following steps S210 to S240:

and S210, establishing the low-power Bluetooth connection with the Bluetooth terminal to be upgraded.

In the initial stage of establishing connection with the bluetooth terminal 120, the interaction can be performed through the bluetooth low energy connection, and this way can improve the connection rate and success rate of the intelligent terminal 110 and the bluetooth terminal 120, and simultaneously, energy consumption is saved.

In an alternative embodiment, when a bluetooth low energy connection is first established with the bluetooth terminal 120, the intelligent terminal 110 starts a bluetooth scanning state, searches connectable bluetooth terminals within a connection range, and simultaneously, connectable bluetooth terminals can transmit connection information of the bluetooth terminals through broadcast signals; when receiving the broadcast signal of the bluetooth terminal 120, the intelligent terminal reads the connection information to obtain a corresponding address, and sends a connection request to the bluetooth terminal 120 where the address is located, thereby establishing a bluetooth low energy connection with the bluetooth terminal 120.

In an optional implementation manner, when the intelligent terminal 110 and the bluetooth terminal 120 do not establish a connection for the first time, when the intelligent terminal 110 scans multiple bluetooth terminals, the bluetooth terminal 120 is automatically selected and establishes a bluetooth low energy connection with the bluetooth terminal, and meanwhile, when there is no data exchange between the intelligent terminal 110 and the bluetooth terminal 120, the bluetooth low energy connection may be in a "half-connection" state, that is, both communication parties only "know" each other, and only when there is data transmission, the connection is opened, and the connection is immediately closed after the data transmission is completed.

By adopting the low-power Bluetooth connection mode in the information interaction process before the data packet is sent, the energy consumption of both interaction parties can be further reduced on the basis of ensuring the reliability of data transmission.

And S220, acquiring the address of the Bluetooth terminal to be upgraded through low-power Bluetooth connection.

The Address of the bluetooth terminal refers to a character for uniquely identifying the bluetooth terminal, and may be used to establish a connection with an external device, for example, a Media Access Control (MAC) Address.

Under the bluetooth low energy connection, intelligent terminal 110 is in the address scanning state, in order to discover the bluetooth terminal serial ports of joinable, when the traditional bluetooth connection serial ports of bluetooth terminal 120 are scanned, can receive the address data package that corresponds about this serial ports that this bluetooth terminal serial ports sent, the transmission of address data package is based on the bluetooth low energy connection, consequently, the transmission reliability of address data package is higher, so receive bluetooth terminal 120 serial ports address's exactness also higher, efficiency and success rate when having promoted follow-up traditional bluetooth connection of establishing.

Step S230, traditional Bluetooth connection with the Bluetooth terminal is established by scanning the address of the Bluetooth terminal.

After receiving the address of the bluetooth terminal 120, the intelligent terminal 110 may automatically resolve correct address information according to the received address data packet, where the address information is a serial address of the bluetooth terminal corresponding to the establishment of the conventional bluetooth connection, and if the address cannot be resolved correctly, the subsequent connection cannot be established. After the address of the serial port corresponding to the bluetooth terminal 120 is analyzed, a serial port connection request is sent to the bluetooth terminal corresponding to the address, and after the bluetooth terminal 120 receives the connection request, a traditional bluetooth connection is established with the intelligent terminal 110.

In an alternative embodiment, step S230 may be implemented by:

sending a data transmission instruction to the bluetooth terminal 120 through the low power bluetooth connection;

after receiving the confirmation information of the bluetooth terminal 120 for the data transmission instruction, scanning the bluetooth signal;

when a bluetooth signal transmitted from the address of the bluetooth terminal 120 is scanned, a conventional bluetooth connection is established with the bluetooth terminal 120.

The data transmission instruction refers to an instruction for the intelligent terminal 110 to send a data packet, and the data transmission instruction may include data information to be transmitted, for example: and when the size of the data is larger than a certain threshold value, establishing a corresponding transmission link for data transmission.

When the traditional bluetooth connection is established, the intelligent terminal 110 sends a data transmission instruction to the bluetooth terminal 120, where the data transmission instruction may be an instruction for the intelligent terminal 110 to send an upgrade data packet, and the bluetooth terminal 120 automatically enters an upgrade data packet download mode when receiving the data transmission instruction through the process; after receiving the confirmation information for the data transmission instruction sent by the bluetooth terminal 120, the connectable bluetooth signal is scanned through the device scanning status, and since the data volume of the upgrade data packet is generally large, the connectable conventional bluetooth address information may be included in the bluetooth signal, and the bluetooth address information is generally composed of a 17-bit character string, for example: "00: 43: A8:23:10: F0"; when the smart terminal 110 scans a bluetooth signal transmitted from an address corresponding to the bluetooth terminal 120, a conventional bluetooth connection is established with the bluetooth terminal 120.

And S240, sending an upgrading data packet to the Bluetooth terminal according to the preset data specification information under the traditional Bluetooth connection, so that the Bluetooth terminal adopts the upgrading data packet for upgrading.

The data specification information is specification information of an upgrade data packet that can be received by the bluetooth terminal 120, for example: size, format, etc.; the upgrade data packet is data information for upgrading the system and repairing bugs of the bluetooth terminal 120, and the data volume of the upgrade data packet is usually large and usually mainly in the form of a compressed file.

Under the conventional bluetooth connection, the data transmission rate is high, so the intelligent terminal 110 can complete the transmission of the upgrade data packet in a short time. In the data transmission process, the intelligent terminal 110 converts the upgrade data packet into a specification that can be received by the bluetooth terminal 120 according to preset data specification information, and then sends the upgrade data packet to the bluetooth terminal 120 through the conventional bluetooth connection.

In an alternative embodiment, the data specification information may include a data size of an upgrade data packet received by the bluetooth terminal 120 once during transmission, and a data packet conforming to the data size is set as a standard data packet, so that step S240 may be implemented by steps S310 to S330 as follows:

and S310, sending the data specification information to the Bluetooth terminal.

The data specification information, that is, the size of each data packet to be received by the bluetooth terminal 120, is sent to the bluetooth terminal 120, so that the bluetooth terminal 120 receives each data packet corresponding to the upgrade data packet in the subsequent data packet transmission process.

And S320, dividing the upgrading data packet into a plurality of data sub-packets according to the data specification information, wherein the size of each data sub-packet is consistent with that of the standard data packet.

Since the size of data that can be received by the bluetooth terminal 120 at a time is limited during data reception, and the size of the data is generally smaller than the size of the upgrade data packet, the upgrade data packet is split into a plurality of data packets having the size consistent with the size of the standard data packet according to the data specification information, and the data packets can be received by the bluetooth terminal 120 in one transmission.

In an optional implementation manner, when the data size of the last split data packet is smaller than that of the standard data packet, the data packet may be directly sent to the bluetooth terminal 120, or may be sent by supplementing a null bit by "0".

And S330, sequentially sending the data sub-packages to the Bluetooth terminal, so that the Bluetooth terminal analyzes the data sub-packages according to the data specification information.

According to the sequence of splitting, send each data packet to bluetooth terminal 120 in proper order, bluetooth terminal 120 can analyze the data packet that is received according to preset analytic mode, for example: the header of the data packet contains the tag information of the data packet, such as: the sequence number of the data packet, the data length, etc., and the tail portion includes the tag information of the next data packet, during parsing, the bluetooth terminal 120 may read the data packet according to the header portion of each data packet, and read the next data packet according to the tag information of the tail portion of the data packet until all data packets are read.

In an optional implementation manner, the data specification information may further include data format information of the upgrade data packet received by the bluetooth terminal 120, where the format information may be sent to the intelligent terminal 110 by the bluetooth terminal 120 in advance, and the intelligent terminal 110 converts the data packet into a data packet conforming to the data format information before sending the data packet, and sends the data packet to the bluetooth terminal 120 in sequence.

In an alternative embodiment, to ensure that the data packets are all received by the bluetooth terminal 120, step S330 may also be implemented by:

after each data sub-packet is sent, monitoring whether the acknowledgement receiving information about the data sub-packet fed back by the bluetooth terminal 120 is received;

transmitting a next data packetization when receiving acknowledgment receipt information on the data packetization;

and when the confirmation receiving information about the data sub-packet is not received, retransmitting the data sub-packet.

After the bluetooth terminal 120 receives the data sub-packet, it may be determined whether the data sub-packet is received according to a preset rule, for example: the intelligent terminal 110 may additionally transmit an acknowledgement number of a fixed byte when transmitting each data packet, and if the bluetooth terminal receives the acknowledgement number, it determines that the data packet is received and transmits acknowledgement information to the intelligent terminal 110, otherwise, it determines that the data packet is not successfully received.

After each data sub-packet is sent, the intelligent terminal 110 may monitor whether receiving the acknowledgement receiving information about the data sub-packet fed back by the bluetooth terminal 120 within a certain time interval, send the next data sub-packet when determining to receive the information, and resend the data sub-packet to the bluetooth terminal if receiving no acknowledgement receiving information fed back by the bluetooth terminal 120 within the time interval indicates that the bluetooth terminal 120 does not receive the data sub-packet.

In an optional embodiment, when the bluetooth terminal 120 receives the data sub-packets, it may be verified whether each data sub-packet is correctly received, and the bluetooth terminal 120 may correctly parse the data sub-packet only when the verification passes.

In an exemplary embodiment of the present disclosure, the correct receipt of the data packetization may be verified by:

after n data sub-packets are sent, sending check values related to the n data sub-packets to the Bluetooth terminal 120, so that the Bluetooth terminal 120 checks the n data sub-packets according to the check values, wherein n is a preset positive integer;

receiving the check result of the n data packets fed back by the bluetooth terminal 120;

if the check result of the n data sub-packets is passed, continuing to send the subsequent data sub-packets;

and if the check result of the n data sub-packets is failed, retransmitting the n data sub-packets.

In an exemplary embodiment of the present disclosure, the Check value may be obtained by a Cyclic Redundancy Check (CRC) method, the method divides a sequence corresponding to the data packet by a "modulo 2 division method" to obtain the Check value, the Check value obtained by the Check method corresponds to the n data packets, and the bluetooth terminal 120 may Check the received n data packets according to the Check value and send the Check result to the intelligent terminal 110. If the returned check result is passed, it indicates that the corresponding n data packets have been correctly received by the bluetooth terminal 120, and continues to send the subsequent data packets; if the returned check result is that the data packet is not received correctly, it indicates that the corresponding n data packets are not received correctly by the bluetooth terminal 120, and the intelligent terminal 110 may immediately resend the n data packets, or resend the n data packets after all the data packets are sent.

After sending all the data packets, the bluetooth terminal 120 may check the analyzed upgrade data packet to determine that the upgrade data packet is correctly analyzed.

In an optional implementation manner, the data specification information may further include a whole package check value of the upgrade data package, and thus, after receiving all data sub-packages, the correctness of the upgrade data package obtained through analysis may be implemented in the following manner:

after all data packets are sent, receiving a check result of the whole packet check value of the bluetooth terminal 120;

if the check result of the check value of the whole packet is passed, the upgrade data packet is determined to be successfully sent;

and if the check result of the check value of the whole packet is failed, determining that the upgrade data packet is unsuccessfully transmitted.

Wherein, the whole packet check value is the check value about the upgrade data packet sent by the intelligent terminal 110, and the bluetooth terminal 120 may check whether the upgrade data packet obtained by parsing each data packet is correct according to the whole packet check value, if: whether the connection order of the data sub-packets is correct or not, whether the data sub-packets are missing or not, and the like.

In an alternative embodiment, the way that the bluetooth terminal 120 parses the received data packet may be determined by a protocol that the bluetooth terminal 120 interacts with the intelligent terminal 110, for example, under a conventional bluetooth connection, a communication protocol between the bluetooth terminal 120 and the intelligent terminal 110 is an SPP (Serial Port Profile), under which the bluetooth terminal 120 may read and write the data packet through a register, for example: and reading data with each byte length according to the format of the received data packet, and performing conversion, encoding and other operations on the data of the information data segment to obtain corresponding information content.

In an alternative embodiment, when the upgrade data packet is unsuccessfully transmitted, the intelligent terminal 110 may retransmit each data sub-packet in sequence.

It should be noted that, when the data sub-packet and the upgrade data packet are verified, the verification may be performed in other manners, for example: a forward error correction coding method, which is a method for checking a data error value at a receiving end by adding a redundancy code and its check information at a transmitting end, and checking and correcting an error code by decoding if the value is within a correctable range, an exemplary embodiment of the present disclosure is explained only in terms of a cyclic redundancy check method.
