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.

That’s spot on—tech can’t replace good design, and a vendor’s words don’t always line up with reality. I always pair with a quick confirmation and double‑check the device’s firmware signatures before pushing any sensitive data. If a company’s privacy policy looks vague, I’ll dig the code or wait for a third‑party audit. It’s better to be cautious than to rely on hype.
