Using Your MP3200
Conne cting MP3200BT t hrough Blueto oth The MP3200BT is equipped with a Bluetooth module which is
compliant with the up-to-date Bluetooth® 1.2 wireless technology.
This enables wireless connectivity between MP3200BT and
most Bluetooth-enabled devices, such as PC, laptop, PDA, PDT
and mobile phone, etc.
Usually, all actions between a program installed on your
computer and a remote Bluetooth device are carried out by the
Bluetooth services. A Bluetooth device can offer one or more
services. These popular services include Serial Port (SPP),
Dail-Up Networking (DUN), Human Interface Device (HID),
Generic Object Exchange (GOEP), Personal Area Networking
(PAN), Lan Access (LAP), Generic Access (GAP), and so on.
The MP3200BT supports Serial Port service (SPP) which is
one of the most popular Bluetooth services providing the serial
radio link between Bluetooth master and slave devices. Under
Bluetooth SPP, the remote Bluetooth system always acts as a
master and MP3200BT always acts as a slave. The MP3200BT
will only wait for the connection request issued by the remote
Bluetooth master system to establish the radio link. Once the
pre-built radio link is lost, the user has to re-build the radio link
manually.
Usually, the resident Bluetooth drivers will configure the SPP
connection as one of the virtual COM ports in your host system
that can be controlled and utilized by the user’s application
programs. If your host system supports the functionality of
PICONET, up to 7 units of MP3200BT can be connected to the
same host system simultaneously. When a PICONET is formed,
the host system acts as the master while the MP3200BTs act as
slaves for the duration of the PICONET connection.
