White Paper W950

Preliminary version - PA4

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 transferring objects between compatible phones. You can use W950 to control electrical devices that have an infrared port, such as, a television or DVD player.

TheFflash memory is split into 48 MB for operating purposes and up to 80 MB for storage of user data, additional languages and settings such as the active theme. This part behaves just like a normal disk drive. The folders can be viewed and managed from the File manager application or from a connected PC.
