Multimachine Bluetooth group communication method based on Android system

Abstract

The invention discloses a multimachine Bluetooth group communication method based on an Android system, which manly solves the problem that when the existing G network or C network is in a weak signal area, the communication quality is poor, and the communication expense is high. The method comprises the following steps: Bluetooth is started by main Android equipment and auxiliary Android equipment, a Bluetooth Adapter is created by the main equipment to search surrounding auxiliary equipment, and the main equipment and the auxiliary equipment are matched and connected to create a Bluetooth piconet; a Thread for each auxiliary equipment is created by the main equipment to monitor a communication request, the Thread created by the main equipment is responded by each auxiliary equipment to initiate the communication request, data is transmitted and received by the main equipment and the auxiliary equipment, and the received and transmitted data is updated to message interfaces of the main equipment and the auxiliary equipment timely. The invention has the advantages that the zero communication expense is realized, the communication effect in the weak signal area is good, in addition, the intervention of a third party is free, and the new method is suitable for the data communication of short-distance smart phones.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to the transmission of data information, specifically, a multi-machine bluetooth group communication method based on an Android system. Background technique [0002] Bluetooth, is a radio technology that enables devices to communicate over short distances. It can carry out wireless information exchange between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of Bluetooth technology can effectively simplify the communication between mobile communication terminal equipment and the communication between equipment and the Internet, thereby making data transmission more rapid and efficient, and broadening the road for wireless communication. Bluetooth adopts a decentralized network structure, fast frequency hopping and short packet technology, and works in the globally common 2.4GHz ISM, that is, industrial, scientif...
