How Do I Programmatically Turn the PPT8866 Bluetooth Radio On/Off?
Facts
PPT8866 WM 2003 running images from DCP1.3
Answer
The Bluetooth radio on a PPT8866 (running WM2003 DCP 1.3 image) can be programmatically turned on or off.
This can be done usingMicrosoft Bluetooth APIs. The APIs areBthGetMode() and BthSetMode(). The Microsoft help file within eVC ++ 4.0 explains their usage. Below is sample source code for BthGetMode(). BthSetMode is similar.
