ojousima / ruuvi-nodejs

Nodejs communication with RuuviTag using upcoming protocol. Runs on Raspberry Pi - unofficial

NOTICE

As of right now, changes in FFI interface prevent ccurl.interface.js from compiling in NodeJS 9+ Please use NodeJS 8.9.4

Usage

Program searches for RuuviTag which has Nordic UART service enabled and automatically connects to first RuuviTag it finds. Please update the RuuviTag with MAM-firmware.

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.

After installing, run node example.js

ruuvi-nodejs's Issues

Cannot Get example.js working.
