The Android platform includes support for the Bluetooth network stack, which allows a device to wirelessly exchange data with other Bluetooth devices. The application framework provides access to the Bluetooth functionality through the Android Bluetooth APIs. These APIs let applications wirelessly connect to other Bluetooth devices, enabling point-to-point and multipoint wireless features.
Using the Bluetooth APIs, an Android application can perform the following:
• Scan for other Bluetooth devices
• Query the local Bluetooth adapter for paired Bluetooth devices
• Establish RFCOMM channels
• Connect to other devices through service discovery
• Transfer data to and from other devices
Bluetooth is being promoted as a cable replacement technology, but it is much more than that. By allowing personal devices like your cell phone and lap top to communicate with each other, data will always be consistent across these devices and remote control of personal devices will be possible. More importantly, the automatic discovery-without user intervention-of public-access devices like printers or LAN access points that are available in meeting rooms or public spaces, will enable a new level of transparent ease of use.
