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.

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.
