O-19 UMAN-CM2/3
A Typical Bluetooth Connection Sequence
In this simplified sequence “Joe’s Terminal” is a
Bluetooth ready hand held terminal running an applica-
tion that needs access to a printer.
1. Joe’s Terminal performs a search of its “piconet” (a
Device Inquiry) and determines that there are four Blue-
tooth devices in the vicinity.
2. Joe’s Terminal queries each of the four nearby de-
vices to determine which services they provide (a Service
Discovery). The Bluetooth enabled Cameo “Sandy’s
Printer” offers the printing service.
3. Joe’s Terminal sends a print connection request to
Sandy’s Printer.
4. Sandy’s Printer evaluates the request and deter-
mines that Joe’s Terminal is permitted to use the print
service,
but only if the correct password is submitted .
5. Sandy’s Printer queries Joe’s Terminal for the pass-
word (Authentication).
6. Joe’s Terminal returns the correct password and the
print connection is established.
7. After Joe’s Terminal is finished printing it disconnects
with Sandy’s Printer. (Some Bluetooth services discon-
nect automatically, others must be closed manually.)
There are several layers of security in the Bluetooth
system, so this sequence may not be a completely accu-
rate representation of how your printer may function in a
Bluetooth environment. For the most part, communica-
tions using the Bluetooth protocol are initiated and pro-
cessed without any operator intervention, much like the
IrDA system described previously.
