After installing, run node example.js Program searches for RuuviTag which has Nordic UART service enabled and automatically connects to first RuuviTag it finds.
Sometimes there is issue with Bluetooth stack, and you'll need to run
sudo hciconfig hci0 reset. Replace the HCI interface number if applicable.
A simple command line interface is given. User is given option to setup temperature sensor for a single-shot measurement, continous measurement (once per second) and querying temperature in plain text. User can also send a MAM query, which will trigger reading environmental data and soon the environmental data is sent from RuuviTag with MAM coding.
The example program publishes MAM data to tangle to fixed address defined in example.js.
You can observe the state of RuuviTag by RED LED, if the led is on or blinking there is activity going on.
