bullet::::- "legacy pairing": this is the only method available in bluetooth v2.0 and before. each device must enter a pin code; pairing is only successful if both devices enter the same pin code. any 16-byte utf-8 string may be used as a pin code; however, not all devices may be capable of entering all possible pin codes.









































bullet::::- "limited input devices": the obvious example of this class of device is a bluetooth hands-free headset, which generally have few inputs. these devices usually have a "fixed pin", for example "0000" or "1234", that are hard-coded into the device.
