Very interesting. What's the max payload size we can transfer with this setup?
This looks like a custom Airtag which is great — but I cannot find where it exfiltrates data from an air-gapped system.
What did I overlook?
Looking at the code, looks like it advertises under a different private key for each bit in each message.

In this age of NFC, WiFi, BT, RFID, and everything in between, I am really not sure that the elite security concept of “air-gapping” is even meaningful or useful anymore.
