Node to read from the Ti SensorTag
The UUID field is the bluetooth mac address of the sensor tag, this is optional and can be used to bind to a specific SensorTag if you have more than one - active in range at the same time. Note:you can only have one SensorTag - per Node-RED instance at the moment.
+ active in range at the same time.The topic setting is a prefix that will be pre-pended to the name of the sensor that creates the reading. e.g. sensorTag/temperature. If blank it will be set to the UUID of the sensor tag.
-NOTE: Only 1 sensorTag can be read from at a time, +
Note: Currently the node can only read from 1 sensorTag at a time, if you add more than one to the canvas then only the first to connect will work.
Linux users should READ THIS.
