  I am using the code available here, https://www.espruino.com/UART.js, to use UART on RuvviTag. According to the uart.js code, it always asks to connect to a bluetooth device. Is there anyway I can modify the code to automatically connect to my RuuviTag?

  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);
