Realization and Application of Multi-machine Communications Based on Bluetooth
D Chen · 2007
Based on bluetooth communication protocol,this paper proposes a multi-machine communication scheme of the control sys-tem in which PC monitors many single-chip microcomputers. Aiming at the bluetooth chip PTR2000,the method of designing multimachine communication and the composition principle of the system are described. The implementation process of bluetooth interface circuits of PC machine and single-chip microcomputer is explained in details. Bluetooth communication protocol,especially large data transmission protocol,is designed. Taking the transmission process of Chinese character for example,this paper also proposes a lattice algorithm to extract Chinese character. The design and implementation process of the software used to transmit Chinese character between upper-machine and nether-machine are described. The experimental result is analyzed and it shows that this scheme proposed in this paper is successful and efficient.
