1.2 Operation of Bluetooth
Bluetooth operates based on the connection between "Master" and "Slave".
Masters are simply supposed to do "Inquiry" and "Page". Slaves are supposed to do "Inquiry Scan"
and "Page Scan".
If a Master finds a Slave and so "inquiry" is successful, a Slave responds to the Master with its
information.
Interconnection between the Master and the Slave is achieved only if the information from the
Slave is corresponded with the Master, and the Slave sends data to the Master.
