getLight

[spycat111]

Hello,

I am trying the following function:

Bangle.setOptions({stepCounter:true,light:true});
Bangle.setHRMPower(1);

But it is giving me an error.

Uncaught Error: Function "getLight" not found!
at line 1 col 18
let lux = Bangle.getLight();

How can I make it work?

Thank you

Bangle.js has no Bangle.getLight() function - what exactly are you trying to accomplish?

There's a reference of what commands you can use at https://www.espruino.com/Reference#software

On second thoughts you're trying to get light level? This might be what you want:

https://www.espruino.com/Reference#l_Bangle_HRM-env

You can do:

Bangle.setHRMPower(1);
Bangle.setOptions({hrmPushEnv:true}).
Bangle.on('HRM-env', function(env) { 
  console.log(env);
});

You can also use:

Bangle.on('HRM-raw', function(h) { 
  console.log(h);
});

to get raw data from the HRM which might be more what you want?

Out of interest, where did you get the code you posted from?

I wanted to calculate a special wellness marker using data such as light exposure.

I am not a programmer, so I am using the help of AI

Ahh, ok - yeah, AI doesn't seem too great at writing code for Espruino I'm afraid - it just makes up all the function names!

I think the problem you have is that Bangle.js doesn't have any forward-facing light sensor, so it'll just be using the heart rate monitor, which probably isn't what you want?
