What is A2DA, what to do with it?

Hi,

There is A2DA written on the display.
It's taking some place so I would like to remove it but cannot determine from what application it comes from. So does somebody know where it comes from?

Cheers,
Bjorn

That will be the "Bluetooth ID Widget"

Thanks @Ganblejs!
I suppose it's better to keep this application. Is there a way to change the value "a2da" into something else? I tried via the IDE but there is no application "Bluetooth ID Widget" installed. Via the watch > settings > apps, there is neither an app to configure the widget.
So is it possible to change the ID?
Thanks!

It's renamed to "widid.wid.js" on the watch, as per https://github.com/espruino/BangleApps/blob/master/apps%2Fwidid%2Fmetadata.json .

Personally I have just uninstalled it.

Yes, just uninstall it. It doesn't do anything useful.

It's designed to display the last digits of the Bluetooth ID (like appears when you connect/pair) so if you have more than one device (eg in a classroom) you know what you're connecting to.

It's on by default because it's quite common for unis/companies to buy more than one device and get running with them out the box, in which case they kind of need it. It's only a few seconds for you to remove it though

Thanks @Ganblejs for your answer. I think I am going to do the same.

Thank you @Gordon! I'll do the same..
I thought it was the ID of the Bluetooth connection. Now I also understand why we cannot change it into something else.

I've removed the app and now it's not visible anymore.. Great! Thanks again @Ganblejs and @Gordon!
