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?
How can you send files over bluetooth when you are not home? You are confusing it with something else. Bluetooth has a 10 meter radius. Also, it is not secure at all, if you send important files and suspect that someone might be eavesdropping within 10 meters, don’t use it
… I assume they have both the phone and laptop with them when they are away from home?
