For another device like a smartphone to use any of the Bluetooth “services” which the board has, it must first be paired with the board. Once paired, the other device may connect to the board and exchange data relating to many of the board’s features.
A board is able to provide a rough measure of the current environmental temperature. It’s an approximation only as in fact the temperature value is inferred from the temperature of its main processor. The Bluetooth temperature service allows another device such as a smartphone to wirelessly find out the board’s current temperature reading or to receive a constant stream of temperature data values. Temperature values are expressed in degrees celsius.
Using the Bluetooth temperature service you could turn your smartphone or tablet into a graphical thermometer using your board as the sensor.
No additional code is needed on the board to use the Bluetooth temperature service from another device.
bluetooth.startTemperatureService();The following code shows the Bluetooth temperature service being started:
