In order to illustrate the technical scheme of the application, the following description is made by specific examples.
The data transmission method of the bluetooth playing device provided in the first embodiment of the present application may be applied in an application environment as shown in fig. 1, where a client communicates with a server. The client includes, but is not limited to, a terminal device with bluetooth function and player function, such as a palm computer, a desktop computer, a notebook computer, an ultra-mobile personal computer, a UMPC, a netbook, a cloud terminal device, a personal digital assistant (personal digital assistant, PDA), etc. The server may be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
Fig. 2 is a schematic flow chart of a data transmission method of a bluetooth playing device according to a second embodiment of the present application, where the data transmission method is applied to the server, and the server and a client communicate through bluetooth. As shown in fig. 2, the data transmission method may include the steps of:
step S201, after the Bluetooth playing device is connected, the Bluetooth playing device is triggered to restart.
In the application, the equipment where the data transmission method is located is connected with the Bluetooth playing equipment so as to realize the subsequent data transmission.
A conventionally connected playback device, the sound system of which is as follows: an audio file directly passes through the sound abstraction layer, calls the sound card drive and directly outputs through the loudspeaker. The sound system of the Bluetooth-connected playing device is as follows: through the path of Bluetooth output, the audio file enters a sound service process (audioservice), then enters a blue alsa process, sound is output to a Bluetooth module through a Bluetooth protocol stack, the Bluetooth module sends the audio file to Bluetooth playing equipment, and the Bluetooth playing equipment drives a loudspeaker to output through a sound card.
For example, a television is taken as a service end, and a bluetooth module of the television and a bluetooth sound box are scanned and paired, wherein the pairing refers to a process of establishing keys for encryption and decryption by a Master and a Slave through negotiation, the pairing method mainly comprises two parts, namely a pairing method and a pairing method Secure Connections, if both support a new method, the new method is used for pairing, and otherwise, an old method is used.
The pairing process mainly comprises four steps:
a: pairing feature exchange (Pairing Feature Exchange) for exchanging the requirements of the double-issue related authentication, and how the double-issue has man-machine interaction capabilities, of which IO capabilities exchange is the most important.
B: public key exchange (Public key exchange) is carried out, public keys are exchanged between the two devices, and once the devices receive the Public keys of the opposite end devices, calculation is started, and an encryption algorithm is determined according to the Public keys.
C: authentication (Authentication), the actual pairing operation is performed by SMP (Service Management Protocol) protocol, and three Authentication methods are selectable according to the result of a.
C1, OOB (Out Of Band), is authenticated with the highest priority, and by the two parties of the pairing, additional information, called OOB, is interacted outside the pairing process, and is taken as input for subsequent pairing operations, and the interaction process of the OOB is also called OOB protocol.
C2, MITM (Man In The Middle) authentication, the two devices negotiate to generate 6 numbers by themselves, and display the numbers, and the users confirm after comparing the numbers.
C3 is Just work protocol, no user participation is needed, and two devices negotiate by themselves.
D: DHKey checking (DHKey Checks), once the device completes the authentication process and DHKey calculation has completed, checks the generated DHKey value, and if successful, both devices will complete displaying information about the process to the user, otherwise the controller sends a message to the host informing it to stop displaying the information, and when the pairing process is completed, link Key can be calculated from DHKey and used as input for the subsequent interaction process informing host through hci_link_key_notification.
After the above process, both parties have generated the encryption key, so that an encrypted connection can be established, and some private information can be mutually transferred.
Triggering to restart the bluetooth playing device may mean that the server generates a restart instruction, and sends the restart instruction to the bluetooth playing device, where the bluetooth playing device performs a restart operation after receiving the restart instruction. In an embodiment, the restart instruction may control the bluetooth playing device to play the corresponding content, so as to instruct the user, the developer, etc. to perform the restart operation.
Step S202, the host control interface is used for obtaining feedback information after the Bluetooth playing device is restarted, analyzing the feedback information and determining target transmission conditions of the Bluetooth playing device.
In the application, after the Bluetooth playing device is restarted, information is fed back to the last connected device, namely, the information is fed back to the server side, and the feedback information needs the server side to use a host control interface (Host controller interface, HCI) for data capture, so that the feedback information after the Bluetooth playing device is restarted is obtained.
The feedback information includes device information, processing parameters and the like of the bluetooth playing device, after the feedback information is acquired, the feedback information is parsed to obtain a transmission condition (i.e., a target transmission condition) corresponding to the bluetooth playing device, for example, the feedback information includes a maximum byte number and the like of the received transmission data that can be processed by the bluetooth playing device, and the maximum byte number can be used as the transmission condition.
Optionally, the obtaining, using the host control interface, feedback information after restarting the bluetooth playing device includes:
monitoring a reconnection action of the Bluetooth playing device after restarting by using a host control interface;
and taking the process information of the loop action as feedback information.
After sending the restart instruction, monitoring by using a host control interface to obtain the reconnection action of the bluetooth playing device, wherein the specific monitoring adopts the following commands:
#hcidump-w xxx.cfa &// xxx.cfa is the name of the saved file
#hcidump hci0 reset
The Bluetooth playing device can generate corresponding information in the process of the back connection action, and the information is feedback information.
Optionally, analyzing the feedback information, and determining the target transmission condition of the bluetooth playing device includes:
extracting a target value representing a maximum transmission unit from process information of the back connection action;
and taking the target value as a target transmission condition of the Bluetooth playing device.
The value representing the maximum transmission unit is extracted from the feedback information, and is the target value, and the size of the data unit cannot exceed the target value when the data is transmitted subsequently, so that the effect of combining rapid transmission and high-quality transmission is ensured. That is, the target transmission condition is that the size of the transmission data is not larger than the target value.
Step S203, the data to be transmitted is modified based on the target transmission condition, and the modified data to be transmitted is sent to the Bluetooth playing device.
According to the application, the data to be transmitted is modified based on the target transmission condition, so that the modified data can be better attached to the Bluetooth playing equipment, and the problems of playing clamping and sound interruption are avoided.
The modification is based on the target transmission condition, for example, if the target transmission condition is a defined transmission data size, the data to be transmitted needs to be processed into a data packet smaller than the defined transmission size, and then transmitted, and if the target transmission condition is a defined data format, the data to be transmitted needs to be formatted into its defined data format, and then transmitted.
Since the bluetooth module of the server and the bluetooth module of the bluetooth playing device may negotiate a protocol result that causes a problem in the bluetooth playing device during negotiation, in order to avoid this situation, the protocol is further limited by adopting the above process.
Optionally, modifying the data to be transmitted based on the target transmission condition, and sending the modified data to be transmitted to the bluetooth playing device includes:
sequentially dividing data to be transmitted according to the size not larger than a target value to obtain sequentially divided data;
and sequentially sending the sequentially segmented data to the Bluetooth playing device according to the segmentation sequence.
Wherein, modifying the data to be transmitted using the target value may mean dividing the data to be transmitted, and the size of the divided data is not greater than the target value. For example, if the default value of the maximum transmission unit (Max transport unit, MTU) is 672, if the method of the present application is used to define, the size of the actually transmitted data is not the default MTU value, but the MTU value confirmed by negotiation is generally larger than 672, the voice data is transmitted with the negotiated MTU value, the effect of actual broadcasting is poor, the phenomenon of jamming can occur in the voice, the transmission distance is very short, and almost no longer than 1 meter can be played, and after the method of the present application is used to define, the size of the actually transmitted data is smaller than 672, the playing effect of the actually transmitted data transmitted to the bluetooth playing device is better, no jamming phenomenon can occur, and the transmission distance can reach about 5 meters.
After the Bluetooth playing device is connected, the Bluetooth playing device is triggered to restart, the host control interface is used for acquiring feedback information after the Bluetooth playing device is restarted, analyzing the feedback information, determining target transmission conditions of the Bluetooth playing device, modifying data to be transmitted based on the target transmission conditions, sending the modified data to be transmitted to the Bluetooth playing device, determining the transmission conditions according to the feedback information when the Bluetooth playing device is restarted, modifying and transmitting files to be transmitted according to the transmission conditions, and therefore compatibility of the Bluetooth playing device can be effectively improved, playing clamping and sound interruption conditions are avoided, and Bluetooth development efficiency is improved.
Fig. 3 is a schematic flow chart of a data transmission method of a bluetooth playing device according to a third embodiment of the present application. As shown in fig. 3, the data transmission method may include the steps of:
step S301, after the Bluetooth playing device is connected, the Bluetooth playing device is triggered to restart.
Step S302, the host control interface is used for acquiring feedback information after the Bluetooth playing device is restarted, analyzing the feedback information and determining target transmission conditions of the Bluetooth playing device.
The content of steps S301 to S302 is the same as that of steps S201 to S202, and reference may be made to the descriptions of steps S201 to S202, which are not repeated here.
Step S303, obtain the protocol transmission condition of the protocol with the bluetooth playing device.
In the application, after the service end negotiates with the Bluetooth playing equipment, the corresponding protocol transmission conditions are also provided, and different results are provided for the protocol transmission conditions due to different Bluetooth playing equipment, especially different manufacturers, so that the service end is required to be acquired after the service end and the Bluetooth playing equipment are negotiated. The protocol procedure is described in step S201.
Step S304, comparing the protocol transmission condition with the target transmission condition to obtain a comparison result.
The protocol transmission condition may be the same as or different from the target transmission condition, so that the two conditions are compared to determine the difference of the two conditions in order to be recognized by the server. In the present application, the target transmission condition is principally dominant, and if the target transmission condition is defined, the protocol transmission condition needs to be dominant.
Step S305, the data to be transmitted is modified according to the comparison result.
In the application, the different comparison results determine different ways of modifying the data to be transmitted, if the target transmission condition is more severe, the target transmission condition is dominant, and if the protocol transmission condition is more severe, the protocol transmission condition is dominant.
For example, taking the MTU value as an example, if the target transmission condition is that the MTU value is smaller than 672 and the protocol transmission condition is that the MTU value is smaller than 700, the target transmission condition is more suitable for the bluetooth playing device, so that the data to be transmitted is modified according to the target transmission condition. On the contrary, if the protocol transmission condition is that the MTU value is smaller than 700 and the target transmission condition is that the MTU value is smaller than 800, the data to be transmitted is modified according to the protocol transmission condition, so that the data to be transmitted are more in line with the protocol content, and the data transmission method is beneficial to transmission.
Optionally, modifying the data to be transmitted according to the comparison result includes:
if the comparison result shows that the target transmission condition belongs to the protocol transmission condition, modifying the data to be transmitted by using the target transmission condition;
and if the comparison result shows that the protocol transmission condition belongs to the target transmission condition, modifying the data to be transmitted by using the protocol transmission condition.
The above-mentioned determination may be performed by determining the size of the limited range of the transmission condition, for example, the target transmission condition is an MTU value less than 672, and the protocol transmission condition is an MTU value less than 700, and it is obvious that the target transmission condition belongs to the protocol transmission condition.
Step S306, the modified data to be transmitted is sent to the Bluetooth playing device.
The content of step S306 is the same as that of step S203, and reference may be made to the description of step S203, which is not repeated here.
After the Bluetooth playing device is connected, the Bluetooth playing device is triggered to restart, the feedback information after the Bluetooth playing device is restarted is acquired by using the host control interface, the feedback information is analyzed, the target transmission condition of the Bluetooth playing device is determined, the protocol transmission condition of the protocol of the Bluetooth playing device is acquired, the protocol transmission condition and the target transmission condition are compared, a comparison result is obtained, the data to be transmitted is modified according to the comparison result, the modified data to be transmitted is sent to the Bluetooth playing device, the transmission condition is determined according to the feedback information when the Bluetooth playing device is restarted, the file to be transmitted is modified by the transmission condition, and the compatibility of the Bluetooth playing device can be effectively improved, so that the situation of playing blocking and sound interruption is avoided, and the efficiency of Bluetooth development is improved.
