Abstract

The invention provides a Bluetooth connection method, which comprises the following steps: S1, sending an empty data packet, and recording the current moment as the sending moment, the empty data packet comprising an access address; s2, judging whether a response aiming at the null data packet is received or not, if the response is judged to be received, updating the access address, then executing the step S1, if the response is judged not to be received, recording the current moment as a judgment moment, then subtracting the sending moment from the judgment moment to obtain data to be compared, and comparing the data to be compared with preset detection time; and S3, if the to-be-compared data is less than the detection time, executing the step S1, and if the to-be-compared data is greater than or equal to the detection time, sending a connection request comprising the access address to realize Bluetooth connection. Before the connection request including the access address is sent, the null data packet including the access address is sent, so that the uniqueness of the access address in the same scene is ensured. The invention also provides a Bluetooth system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a bluetooth connection method and a bluetooth connection system. Background technique [0002] In Bluetooth communication, each pair of master device and slave device must ensure the uniqueness of the access address, and the access address must meet the following requirements: the size of the access address data is 32 bits, and the access address Any consecutive 6 bits of the 32 bits of data cannot be 000000 or 111111; the value of the access address cannot be the same as the broadcast access address 0x8E89BED6; the number composed of 1-8 bits of the access address cannot be the same as The 9-16 bits, 17-24 bits, and 25-32 bits of the access address consist of the same number; the bit transition from 0 to 1 or from 1 to 0 is called a bit flip, and the access address cannot have more than 24 bit flips; the last 6 bits of the access address require at least two bit flips. ...
