INTERVIEW QUESTIONS COMPUTER HARDWARE BLUETOOTH DETAILS

Question: Please explain the working of bluetooth how the data are transfered through this method?

Answer: As far as i know before any data transfer takes place a connection has to be established between the master and the slave devices . So during establishment of connection we can establish either a ACL link or a SCO link . ACL stands for Asynchronous Connectionless link and SCO stands for Synchronous conetion oriented .
So during the connection establishment the master sends an inquiry packet to the slave and the slave in return sends a Frequency Hopping Sequence packet (FHS) packet . This FHS packet contains information regarding the clock time the clock offset and other details which are required to set up the connection .

So after receiving the FHS packet we know that there is a device and its address . So the blue tooth device along with the device address and other standard 802.11b packet structure sets up a connection . Once the connection is established you can start transferring data to and from the device.
