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.
Used enablers and bearers
The HID based remote control function works over
a Bluetooth connection. It is possible to download
the HID configuration files via an infrared, WLAN,
USB or Bluetooth connection. It is also possible to
transfer the files to another device using an infrared
or 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.
IrDA
IrDA (Infrared Data Association) is a point-to-point
communication link between two infrared ports.
The infrared beam has to be directed towards the
target infrared port and as long as the two infrared
ports are within sight and range, the devices can
exchange data.
Object Exchange via infrared (IrObex) supports the
transferring of objects between compatible
phones. Sony Ericsson P1 can be used to control
electrical devices that have an infrared port, such
as, a television or DVD player.
USB
Sony Ericsson P1 is USB 2.0 FS (12 Mbps)
compliant. The idea of the USB port is to allow
easy connection of the phone to a computer.
USB is designed to be completely “Plug and Play”,
that is, devices will be correctly detected and
configured automatically as soon as they are
attached. USB in a mobile phone means
convenient data transfer between the phone and a
computer.
Sony Ericsson P1 supports USB charging, which
means that the user can have the phone battery
charged while USB connected to, for example, a
computer. This possibility is very useful if the user
travels a lot.
