Javascript write to bus doesn't work

[jmir]

Hi,

I've been trying to write an address to the bus using this javascript code:

$(function(){
  grp.write('2/5/1',true); 
});


Inside the browser console it appears this error:



Do you know what's happening? I'm pretty sure that I'd been using it before and it worked...

Thanks.

Do you have any object on this page?

Another possibility is that websocket is not connected yet. Try running the same grp.write call from browser console.

Not in this sample. But I've tried adding an object and appears the same error...

From browser console it works.

How can we solve it?

As admin mention add a delay before sending

Code:

$(function() {   
  setTimeout(() => { grp.write('2/5/1',true) }, 2000); 
});
