How can I check if a Bluetooth device is still paired?

Alright, so I tried this, and I still get true for index 1, and there is no second index.

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

After connecting to a Bluetooth device, I want to be able to always know if that device has disconnected or not.

You have to constantly send (i.e. poll) something to the device. As soon as you get error 516 you know, that the device disconnected

EDIT: see an example here

Screen reporting when bluetooth disconnect

I send a text to BT every 20 or so seconds to test if it is still connected. If not, a screen error will be flagged and I use that to propt the error to the user. The call notifier block has no function here other than keeping my phone awake. [NoBT]
