How secure is sending files over Bluetooth? (lemmy.ml)

If I pair my Android phone and my laptop, I can share files over Bluetooth from the phone to the laptop. I've started finding this a really convenient method for me to send files to a Linux laptop without needing to install a separate app on either the phone or my laptop. Especially when I'm away from my home network (I use SFTP at home).

How secure is this? Is there encryption by default and could someone else nearby with a receiver potentially decode the file you're sending?

Low odds because “you aren’t worth the effort required” agreed.

But the distance officially is like 33 feet to 300 feet depending on the adapter.
