Bluetooth

For more information, see the C++/Bluetooth Special Interest Paper at Sony Ericsson Developer World.

IMEI, IMSI

The IMEI number can be obtained by reading C:\System\plpvar.ini

The IMSI number can be obtained by reading C:\System\data\imsi.txt

Colour display

The P910 has a colour-depth of 262K, the P900 has a colour-depth of 65K and the P800 4K. Applications requiring direct access to the screen will encounter problems with devices. It is therefore recommended that applications use the CDirectScreenAccess method. This method is described with an example in the SDK in:

<SDKROOT>\examples\Graphics\WS\Direct\

and

<SDKROOT>\examples\Graphics\2DAccel

The latter shows how to query the system to obtain the resolution used by the device.

Audio

Programmers can use the versatile audio engine available in the P800, P900 and P910 series mobile phones. The mobile phones use Beatnik Audio Engine, Mini Edition (MiniBAE) to reproduce high quality MIDI sounds and is able to play different media types together, at the same time.

To extend your applications with high quality sound effects, use the miniBAE devkit available from Sony Ericsson Developer World.

Media server

The Media server is ‘single threaded’. This means that audio recording/playback and image operations cannot be done at the same time without affecting each other. Applications that use the Media Server should take this into consideration and ensure that they break up long operations (for example, converting a GIF to a BMP) into smaller steps. In this way, the Media Server is able to serve both the audio and the image requests in a reasonable amount of time.
