Method Summary

Methods

Modifier and Type	Method and Description
byte[]	Acquire(String sensor, String query) Method to acquire sensor data Here, start BT discovery thread in case it hasn't run yet
void	destroyHandler() Method to release all handler resources Here, we interrupt the discovery thread and stop any ongoing BT discovery
void	Discover() Method to discover the sensor symbols support by this handler As the result of the discovery, appropriate Sensor entries will be added to the SensorRepository Here, we also check if the BT adapter is available and also enable it, in case it is disabled and it is configured (by the user) to switch BT on Furthermore, we register the receivers for getting BT connect and disconnects messages
void	History(String sensor) Method to view historical chart of the given sensor symbol
void	run() BT Discovery thread, being executed every polltime seconds, using the sleep() function to wait
String	Share(String sensor) Method to share the last value of the given sensor
