Bluetooth returns "false" or "true" labels to my screen

[e124506]

Hello,
this is my first app and i tried it on my phone (samnsung note 8)

I aimed to select bluetooth address from list picker.
APPis working good (bluetooth connection is established and light control can be done)
But durng operation there is a strange text which i could not find the reason.

if the bluetooth connection is ok it gives “true” unless “false”
ın my blocks i did not select such a text.
what is the reason of this?
how can i prevent this?

I think it’s because of the ListPicker.Text, you can avoid it by Control / evaluate but ignore result.
