Coverage Area
The area where two Bluetooth units can exchange messages with acceptable
quality and performance.
Destination
The Bluetooth device receiving an action from another Bluetooth device.
The device sending the action is called the source. The destination is
typically part of an established link, though not always (such as in inquiry/
page procedures).
Device Discovery
Before a link can be established, a Bluetooth device needs to discover the
other Bluetooth devices that are active within the range. The mechanism to
request and receive the Bluetooth address, clock, class of device, used page
scan, and names of devices is referred to as device discovery.
Device Name
The name that a Bluetooth device presents when supplying identity
information to another device.
DH (Data-High Rate)
An ACL link data packet type for high-rate data. DH1 packets are similar to
DM1 packets, except that the information in the payload is not FEC
encoded. This means the DH1 packet can carry up to 28 information bytes
and covers a single time slot. The DH3 is the same, except it can cover up to
3 time slots and contain up to 185 information bytes. The DH5 packet is the
same again except it can cover up to 5 time slots and contains up to 341
information bytes.
Discoverable Device
A Bluetooth device in range that will respond to an inquiry message.
DM (Data-Medium Rate)
An ACL link data packet type for medium rate data. DM1 packets carry
information data only, containing a 16-bit CRC code and up to 18 info bytes.
They are encoded using 2/3 FEC and the packet can cover up to a single time
slot. DM3 packets are the same except they can cover up to 3 time slots, and
can carry up to 123 information bytes. DM5 packets are the same again
except they can cover up to 5 time slots and can hold up to 226 information
bytes.
DV (Data Voice)
A SCO (synchronous connection oriented) link data packet type for data and
voice. It is divided into a voice field of 80 bits and a data field of 150 bits.
The voice field is not covered by FEC, but the data field is covered by 2/3
FEC. The voice and data fields are treated completely separate. The voice
field is handled like normal SCO data and is never retransmitted; that is, the
voice field is always new. The data field is checked for errors and is
retransmitted, if necessary.
