Error: Unknown event type

muscaiu commented 4 years ago

I'm using the library to read the Mi sensor on a node js app and this is the whole code. i'm using. It works correctly by logging the temp and humidity, but after 5-10 minutes it crashes. Any idea why?

const { Scanner } = require("homebridge-mi-hygrothermograph/lib/scanner");

const livingId = '4c65a8dd7fc9';
const log = { debug() { }, error() { }, warn() { }, info() { } };
const livingScanner = new Scanner(livingId, { log });

try {
  livingScanner.on("temperatureChange", function (temperature, id) {
    console.log(temperature)
  });

  livingScanner.on("humidityChange", function (humidity, id) {
    console.log(humidity)
  });
} catch{
  livingScanner.on("error", error => console.log(error));
}

Error:

events.js:174
      throw er; // Unhandled 'error' event
      ^

This is a duplicate of https://github.com/hannseman/homebridge-mi-hygrothermograph/issues/56.

My current understanding of this issue is that something changed in the raspberry-pi firmware earlier this year and this broke a lot of bluetooth related stuff. Some people have seen improvement by upgrading to the latest firmware and others have resorted to buying external bluetooth adapters or upgrading to the RPI 4.

I was thinking of buying a RPI4 because of the 64 architecture, now you just gave me an extra reason!
