Wireless data communication method, system and device and storage medium

Abstract

The embodiment of the invention provides a wireless data communication method, system and device and a storage medium. The method comprises the steps: establishing a communication relationship between a first wireless communication device and a second wireless communication device based on the SWISS communication protocol; distinguishing the first wireless communication device and the second wireless communication device as a host and a slave according to whether the SWISS communication service is registered or not, and endowing the host and the slave with different interaction permissions based on role distinguishing; enabling the host and the slave to establish SWISS communication protocol connection based on an RFCOMM channel after successful pairing, enabling the host to provide SWISS communication service for the slave to find by registering the SWISS communication service, and receiving a request initiated by the slave in the connection process; enabling the slave not to register the SWISS communication service, discovering the host with the SWISS communication service through the SDP, and initiating a connection request to the host in the connection process. Therefore, the communication interaction of the data flow, the control flow and the state flow is realized between the host and the slave.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a wireless data communication method, system, device, and storage medium. Background technique [0002] Bluetooth technology, which belongs to a short-distance, low-cost wireless connection technology, uses low-energy radio communication technology to realize voice, data and video transmission, which can effectively simplify the communication between mobile communication devices that are easily carried. [0003] At present, the types of mobile communication devices supporting Bluetooth technology are diversified, not only limited to handheld computers, notebook computers, mobile smart phones, etc., but also can be applied to earphones, handles, watches, etc. And there is a need for Bluetooth communication between the host and the slave. However, the current Bluetooth communication protocol cannot realize the role distinction between the mas...
