Creating CSV file for Ruvvi data using Espruino

I just wanted to know if it is possible to log data from RuvviTag into a CSV file using Espruino. If any code is available it would help a lot.

This is the code I'm using to print values on the console

const period = 30*60*1000; // milliseconds (every 30 minutes)
const length = 200; // number of records (for 100 hours / 4 days)

var ruuvi = require("Ruuvitag");
var records = [];

function log() {
  ruuvi.setEnvOn(true);
  if (records.unshift({time:getTime(),temp:ru­uvi.getEnvData().temp}) > length){
    records.pop();
  }
  ruuvi.setEnvOn(false);
}

function getData() {
  records.forEach( function(d,i) {
    console.log(i+"\t"+ d.temp +"\t"+ (getTime()-d.time));
  });
}

ruuvi.setAccelOn(true);
setInterval(log, period);

So you're storing the data on the tag - you just want a way to get the data out of it into a CSV file? Effectively calling getData() and writing that to a file?

Yes

Ok - the easiest thing would be to make a Web Bluetooth website. I'll add a very specific code example for this tomorrow.

Ok, it's now at http://www.espruino.com/Data+Collection#­automatically-recovering-data
