That is correct.

But all my [modern] Apple devices randomize (except my old SE, which is my low-end test). It can be a pain to track, with my software.

BLE is probably where all of Bluetooth is going, eventually.

The main issue, now, is data speed, but even classic is pretty slow, compared to other standards. I believe they are incorporating high data-rate stuff into BLE, so you can have things like pure BLE headphones.

so, there are cases where btle does randomize the mac address, but not when using 'normal' bluetooth things

BLE is "ad hoc," with ephemeral, one-time connections, while Classic establishes long-lasting, "commitments."

BLE is like a Gig.

Classic is more like a Career.
