Out of hand means a way of sharing the encryption keys by some other means than the 2.4GHz band

I believe this article explains better than I do: hmmyes https://www.design-reuse.com/articles/47133/enabling-bluetooth-out-of-band-pairing-through-nfc.html

Enabling Bluetooth Out-of-Band pairing through NFC

Many services offered over Bluetooth can expose private data or let a connecting party control the Bluetooth device. Security reasons make it necessary to recognize specific devices, and thus enable control over which devices can connect to a given Bluetooth device.

I see

#

I thought you were thinking transmitting Encryption Keys via SubGhz, which made me confused for a sec, cause the other device would have to have a chip as well

#

What data has to be sent over NFC?

#

Is it some simple text or what does it look like?

#

Also what devices support OOB? What does your usecase look like?

#

I'm mildly curious

For OOB pairing, it’s mainly Bluetooth ID and the credentials, in NDEF message
