Bluetooth Accelerometer Service

~hint

For another device like a smartphone to use any of the Bluetooth "services" which the @boardname@ has, it must first be paired with the @boardname@. Once paired, the other device may connect to the @boardname@ and exchange data relating to many of the @boardname@'s features.

~

The Bluetooth accelerometer service allows another device such as a smartphone to wirelessly receive data from the @boardname@'s accelerometer. An accelerometer detects motion. More precisely, it measures acceleration in one or more of three directions which we call X, Y and Z.

Using the Bluetooth accelerometer service you could, for example, create a smartphone application which makes a loud noise whenever your @boardname@ (or the important thing you've attached it to) is moved. Or you could use your @boardname@ to control the movement of a cartoon character in a game on your smartphone just by tilting the @boardname@ in the direction you want the character to move in.

No additional code is needed on the @boardname@ to use the Bluetooth accelerometer service from another device.

bluetooth.startAccelerometerService();

Example: Starting the Bluetooth accelerometer service

The following code shows the Bluetooth accelerometer service being started:

bluetooth.startAccelerometerService();
