Abstract

The invention discloses a wireless communication device and a wireless communication method. The wireless communication device comprises a main control unit, an antenna, a radio-frequency matching circuit, a power supply circuit, a clock circuit and a communication interface circuit; the radio-frequency matching circuit, the power supply circuit, the clock circuit and the communication interface circuit are respectively connected to the main control unit; the antenna is connected to the radio-frequency matching circuit; and the main control unit is a Bluetooth chip, so that wireless communication control based on a Bluetooth technology is realized, wherein Bluetooth communication data is processed by adopting a protobuf coding and decoding method. The wireless communication device and the wireless communication method disclosed by the invention have the advantages of being standard in Bluetooth protocol, convenient to access to mobile equipment, low in development cost, convenient to develop, low in power consumption, small in volume, customized in underlying client protocol and the like; preferably, synchronous parameters of upper and lower computers are added into a defined protobuf file; man-in-the-middle attack can be effectively prevented when the data is transmitted; and thus, the transmission security is improved.

Description

technical field [0001] The invention relates to a wireless communication device and a wireless communication method. Background technique [0002] At present, wireless communication modules based on Bluetooth technology, such as IMB's Z60T, SPP-C series, ACER's 4551, 4771, etc., these similar products use communication standards below 3.0, and they do not have a low-power physical layer. , Low-power link layer, advanced AES-128 data encryption, SecurityManager, and Profile are several important functions and features. There are also some wireless communication modules that use Bluetooth 4.0 technology, such as the HM-10 Bluetooth module, HC-05 Bluetooth module, HC8650 module, RF-BM-S02 module, etc. on the market. Although these similar products have also been updated to the 4.0 standard, However, these products are all made of serial port transparent transmission, so that users cannot change the communication protocol, limited by the fixed format of communication data forma...
