Abstract

The invention relates to a bluetooth adapter with NFC function, comprising a broadcast module for sending a broadcast message, the broadcast message contains a connection request; a first receiving module for receiving feedback information, the feedback information is to be received The terminal receives the time node of the broadcast message and the identity information of the terminal to be connected; the processing module selects the pre-connection terminal according to the identity information in the feedback message; the creation module creates a channel between the pre-connection terminal and the processing module; the transmission module The information to be transmitted of the pre-connected terminal is transmitted to the processing module through the channel; the second receiving module receives the compensation data from the cloud to complete the information to be transmitted. Determine the length of data to be transmitted in the cloud and the signal strength to be compensated according to the preset standard signal strength and standard data loss rate in the processing module, and retransmit the lost data length through the cloud, so that the second receiving module receives the complete data information to be transmitted.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a bluetooth adapter with NFC function. Background technique [0002] Bluetooth (Bluetooth) is a kind of wireless network transmission technology, originally used to replace infrared. Compared with infrared technology, Bluetooth can transmit data without alignment, and the transmission distance is less than 10 meters (the transmission distance of infrared is within a few meters). With the help of the signal amplifier, the communication distance can even reach about 100 meters. Bluetooth technology is very suitable for digital devices with low power consumption to share data with each other, such as mobile phones and PDAs. [0003] Near Field Communication (NFC) is a short-range high-frequency radio technology that operates at a frequency of 13.56 MHz within a distance of 20 cm. Therefore, usually when the distance is within a certain range, after the connection request is initi...
