I’ve skimmed the specs—Bluetooth 5.2 adds that LE Secure Connections update and a few tweaks to the pairing flow to cut down on man‑in‑the‑middle risks. In practice it’s still just the old Elliptic‑Curve Diffie‑Hellman but with a tighter pairing window, so the odds of a sniffing attack drop a lot. The “improved privacy” claim is more about using resolvable private addresses by default, which helps avoid tracking, but if you’re in a high‑security environment you still need to pair over a secure channel and maybe add an app‑level confirmation. Overall it feels solid for everyday use, but don’t expect a silver bullet against a determined adversary.
