For another device like a smartphone to use any of the Bluetooth “services” which the Calliope mini has, it must first be paired with the Calliope mini. Once paired, the other device may connect to the Calliope mini and exchange data relating to many of the Calliope mini’s features.
The Bluetooth accelerometer service allows another device such as a smartphone to wirelessly receive data from the Calliope mini’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 Calliope mini (or the important thing you’ve attached it to) is moved. Or you could use your Calliope mini to control the movement of a cartoon character in a game on your smartphone just by tilting the Calliope mini in the direction you want the character to move in.
No additional code is needed on the Calliope mini to use the Bluetooth accelerometer service from another device.
bluetooth.startAccelerometerService();The following code shows the Bluetooth accelerometer service being started:
