File sharing
By using the Server role of the File Transfer Profile,
the phone enables the use of a computer to
manage content files that reside in the phone’s file
system. Most computer Bluetooth applications
provide an explorer-like user interface for the file
transfer service. The content in the Games and
more folder is not exposed in the file transfer
server. Opening one of the folders will show a list of
files related to that folder, such as, images in the
Pictures folder. Using the computer application the
user can now: retrieve files from phone to
computer, delete files from the phone and transfer
files from the computer to the phone using the
normal drag and drop mechanisms provided by the
computer.
File browsing
By using the Client role of the File Transfer Profile,
the phone enables the user to access file systems
of other devices, that also support the Server role
of the same profile. After pairing the phone with the
other device, the user can connect to the other
device by selecting it in the ‘My devices’ list on the
Bluetooth menu and selecting the browse option
that should be available on the left selection key. If
the browse option does not appear the user can
select the Service option to update the phone’s
knowledge that file browsing is possible to use with
the device. When the phone is connected to the file
server, the user can browse the shared folders and
retrieve files listed in different folders. Files are
transferred to the file server device using the
normal Send/via Bluetooth option.
Media viewing
The phone can send images and sounds to a
media viewer device, such as, the MMW-100 TV
adaptor accessory. The user can also conveniently
run a slide show on the TV showing a set of nice
phone camera pictures for family and friends. The
phone can connect to a Bluetooth device that can
receive images, the image can be transferred to the
remote screen and displayed.

Remote control
The phone keypad is configured for control of a
certain computer application through a special
type of HID configuration file consisting of an XML
file for the keypad and an image for the display.
HID configuration files can be downloaded into the
phone using the normal file transfer mechanisms.
Users can even modify the files themselves on their
computers. A few configuration files, pre-loaded in
the phone, enable the user to navigate on a
computer desktop and control presentations and
Media players.
System functions
Characteristics
The HID configuration files, and the set of
predefined HID configuration files, are
customizable. The configuration files can be
modified by the user if transferred to, and opened
on, a computer.
Enablers and bearers
The HID-based remote control function works over
a Bluetooth connection. It is possible to download
the HID configuration files via a Bluetooth or USB
connection. It is also possible to transfer the files to
another device using a Bluetooth connection.
Power save mode
The phone uses sniff mode on headset, handsfree
and HID connections which means reduced power
consumption and shorter connection set-up times.
