I've read a bunch of different numbers around 30, but I've never used beacons personally. I pulled out my copy of the O'Reilly book on BLE (covers up to Bluetooth 4.1), which says this > Each advertising packet can carry up to 31 bytes of advertising data payload, along with the basic header information (including Bluetooth device address). I didn't know about advertising extensions, thanks for the info. Without that I'm not sure if supply chain verification is feasible? I also wonder if there's a significant battery impact to broadcasting more data. I suppose they could overload the device address uuid?
