I think the problem is that in this case Bluetooth is just not fast enough to transfer large amounts of video data. What they should do is use BT to negotiate details of an ad-hoc Wi-Fi network and use that larger pipe to send the actual data.

Yup. This is how Wifi Direct and Apple's Airdrop work.

That is exactly how the Spectacles work. Bluetooth is only used for transfer as a fallback mechanism.

This random thing I found claims about 1-1.5MB/s possible at least using the multipeerconnectivity libraries. ~ 0.1MB/s for bluetooth-only. https://github.com/thaliproject/Thali_CordovaPlugin/issues/1562 https://github.com/thaliproject/Thali_CordovaPlugin/issues/1...

You basically just described Bluetooth 3.0 + HS[1]. The Bluetooth connection is used to establish an 802.11 link, over which data is transferred. It's only (up to) 24 Mbit/s, so it's still slower than some (direct) Wi-Fi alternatives, but it's much faster than normal Bluetooth connections.
