Standardof the protocol which is used for the occasion where it communicates with Bluetooth, is decided in every typeof equipment.

General purpose as for Bluetooth which is short range radio communicationtechnology, the various information equipment correspond, can exchange the data. At that time,through the personal computer and the like, the equipment transferring the data directly, also the applications that are supposed it utilizes mutual function.

Because of this,withBluetooth like former communication technology establishing the circuit simply, if only it can transfer the data, being insufficient, it is necessary to standardize the procedure which hits to "the method of using" the equipment with some kind of order timing, it should transfer the information of some type. ... The continuation is read

Such equipment specific communication procedure(protocol) those which are standardized in every quality of the product are Bluetooth profile. Besides the fact that profileof standardis decided in every type of equipment by Bluetooth SIG of the economic organization, stopping the individual profile to which the manufacturermountsthe respective company specific function also it is possible to offer.

For example,casewe would like to printthe picture whichthe digital camera retains by mywith the nearby printer, printer profile (Printing Profile) using, it communicates,requestsprinting at the printer.Whenwe would like to look throughthe picture whichthe personal computer retains the digital camera, if digital camera profile (really, the profile, "Still Image Profile" is used) using, transfer of the data should have been requested.

There is also a profile which decides the specification which other than equipment specific profile "Generic Access Profile" and "Serial Port Profile" and so on, is located on the lower stratum of other profile, is in common.
