[0038] The implementation, functional features, and advantages of the present invention will be further described with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

The specific embodiments described herein are intended to be illustrative only and not to limit the invention.

[0040] Referring to FIG. 1, an embodiment of a method for reading data of interaction between an iOS device and a Bluetooth device according to the present invention includes the following steps:

[0041] Sl, the iOS device receives data sent by the Bluetooth device, where the data carries a tag, where the Tag occupies 1, 2, or 3 bytes; [0042] S2, analyzing the number of bytes occupied by the tag;

[0043] S3. Read the content behind the Tag in the data according to the number of bytes occupied by the Tag.

[0044] In the foregoing step S1, the data includes a tag, a number of bytes of the read data body, and a data body; the tag represents a function of the data, the tag carries more content, and the information carried by the data is richer, and the functions are multiple. Information can be fully reflected in one piece of data. When the same function is implemented, fewer data pieces are needed, the number of tags is reduced, the occupied data space is reduced, and the processing efficiency is higher.

[0045] An iOS device refers to a terminal device such as a mobile phone or a tablet computer with an iOS system installed.

[0046] Tag does not have a unified Chinese name in China. Some call it "classification", some call it "small class" or "mass classification", and others call it "tag".

[0047] Labels are a more flexible and interesting way to classify logs. You can add one or more tags to each log, and then you can see all the logs on the BlogBus that use the same tag, and thus generate it with other users. More contact and communication. The tag in this embodiment is a tag.

[0048] In the above step S2, by analyzing and determining the correct number of bytes occupied by the tag, the Tag and the part of the data representing the number of read data bytes can be correctly distinguished, and the number of bytes occupied by the tag is constantly changed. Apple mobile phones and Bluetooth devices interact with data normally.

[0049] In the above step S3, the content after the Tag is the number of bytes of the read data body and the data body, and only the number of bytes occupied by the T ag is correctly read, so as to ensure the number of bytes and the data body of the read data body. Correct, ensure the correct reading of the entire data, to ensure that the Bluetooth device has a flaw and the normal operation of the mobile phone.

[0050] Referring to FIG. 2, step S2 includes the following steps:

[0051] S21, detecting whether the number of bytes occupied by the tag is greater than one byte, and if not, the number of bytes occupied by the tag is 1;

[0052] S22, if yes, detecting whether the number of bytes occupied by the tag exceeds two bytes, and if not, the number of bytes occupied by the shell IjTag is 2;

[0053] S23. If yes, the number of bytes occupied by the tag is 3.

[0054] In the above step S21, it can be detected whether the number of bytes occupied by the tag is greater than one byte, and further whether step S22 is to be performed.

[0055] In the above step S22, it can be detected whether the number of bytes occupied by the tag exceeds two bytes, and when it exceeds two bytes, step S23 is performed, and when the part exceeds two bytes, the tag takes up The number of bytes is 2. [0056] In the above step S23, it is determined that the number of bytes occupied by the tag is 3, and the number of bytes occupied by the tag is at most 3. Therefore, when the number of bytes occupied by the tag is detected in step S22, the number of bytes exceeds two words. Thrift, you can determine that the maximum number of bytes occupied by the tag is 3.

[0057] In other embodiments, the number of bytes occupied by the tag may be more than three, and step S23 may determine the maximum number of bytes occupied by the tag; after step S22, there may be a corresponding number of similar steps. The number of bytes occupied by the detection tag is more than three, four, five, and so on.

[0058] Referring to FIG. 3, the method for detecting whether the number of bytes occupied by the tag is greater than one byte is as follows:

[0059] S4, the first byte of the Tag & operation OxlF is 0x11; when it is no, the Tag occupies 1 byte; when it is 吋, the Tag occupies more than 1 byte.

[0060] In the above step S4, the calculation rule of the & operation is that if both numbers are true (or 1), the result is true, if one of the two digits is false (or is 0), the result is true. False, for example, 00001011 & 00000111 = 00000011; OxlF Ox stands for hexadecimal, that is, the binary code represented by Oxlf is 00011111; the binary code represented by 0x11 is 00010001.

[0061] Referring to FIG. 3, the method of detecting whether the number of bytes occupied by the tag exceeds two bytes is as follows:

[0062] S5, the second byte of the tag & operation 0x80 is not equal to 0; when it is no, the Tag occupies 2 bytes; when it is 吋, the Tag occupies more than 2 bytes.

[0063] In the above step S5, the calculation rule of the & operation is that if both numbers are true (or 1), the result is true, if one of the two digits is false (or is 0), the result is true. False; 0x80 represents a binary of 1000000

0; 0 represents the binary code is 00000000.

[0064] The method for reading data exchanged between the iOS device and the Bluetooth device in the embodiment of the present invention, by analyzing the number of bytes occupied by the tag, can correctly determine the number of bytes of the read data body, and the amount of information that the Tag can carry is more Large, the data is more scalable.
