The big picture here is about how brutally complex it is to build a real database on dumb cloud primitives. They had to implement Record Managers, Page Managers, and buffer pools entirely on the client side, in order to cluster tiny records into pages. For distributed coordination, they hack SQS into a locking system with dedicated LOCK queues and carefully timed tokens. On top of that, they have to handle SQS quirks, with idempotent log records as we discussed above. The engineering effort is massive.

I am no BT or Android expert at all. For what I've learned, one could also dig deeper into the communication of the smart glasses by sniffing the BLE traffic. By doing so, we would likely not need to rely on the device behaving according to the BT specifications but could also use heuristics on the encrypted traffic transmissions without much false positives. But I haven't looked into BT traffic packets for more than ten years. I'm glad I remembered ADV frames... So if anybody could help on this, that'd be greatly appreciated!
