Bluetooth embedded module can be applied to electronic information products area which include all kinds of household wiring ,instrument(such as medical equipment).it realizes the wireless data transmission of equipment with plug and play as a lable substitute project.it has the main equip and the subordinating one,they are used pairly. When Bluetooth general module connects correct circuit and electromotion ,the two equipment will establish connection automatically and identify with each other?s equipment.ultimately,user?s facility could use Bluetooth embedded module alike the use of a serial interface.
Bluetooth embedded module can also be used independently. If user?s facility connect a Bluetooth embedded module of a subordinating one.By these ,other Bluetooth equipments such as Bluetooth PDA can establish connection and communication by searching for the general module and discoering its service. For communication of user?s facilities,it can also use the module alike the use of a serial interface.
Bluetooth embeded module provide security allthentication function .when user set and use the function,the connected equipment must be given differentiated, as it is the foundation of communication.Meanwhile,if it is a pair module,these process will be completed automatically.(default code:1234)
Sketch map as follow,the picture 1 shows what A and B used is serial interface,the picture 2 shows what they used is Bluetooth embedded module.they are both thougt to be a serial lines.the third one shows the connected situation of blue embeded module and other Bluetooth equipment ( refers to Bluetooth PDA),in which ,the are similar with picture1 and 2 for uer?s equipment.
