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.
