Unknown Bluetooth Connections (Hacked?)

I’ve had unknown bluetooth connections for a while (end of November) and i’m fed up with it. I’ve asked for help to the computer scientist at my school and they said they couldn’t help since it was through bluetooth and that they didn’t know what to do.

I've searched on the internet to find some answers but i feel like they didn’t really help me. I figured it might be an attack through BLE or something but i really don’t know.

I think someone might be trying to hack me but I don’t think someone at my school has the skill to do something like this.

I have a picture of my problem attached, JVC are my earbuds the other connections are unknown.

My Ipad is an Ipad pro 3rd generation.
