> Prior work exists: animated QR sequences that flash frames until the scanner captures all parts23, and fountain codes (TXQR4) that tolerate missed frames. These achieve ~9 KB/s under ideal conditions but require holding steady for 10+ seconds
Consideration for Photosensitive epilepsy; how to avoid this risk? What bitrates are realistic given these updated constraints?

But Gemini says that's deprecated since 2021; to instead use a third-party library like AltBeacon for finding BLE beacons:
AltBeacon/android-beacon-library: https://github.com/AltBeacon/android-beacon-library :
> By default, this library will only detect beacons meeting the AltBeacon specification.
> If you want this library to work with proprietary or custom beacons, see the BeaconParser class.

What are BLE beacon chipsets and costs, and what bitrates can a BLE beacon push?

mDNS does only local network segment peer discovery for e.g. Printers, Chromecast, and Matter devices.
