Conventional Bluetooth Beacon hardware devices are fixed in position and are used to determine location rather than for asset tracking.
BAP tags are used for asset tracking using the standard Bluetooth beacon protocol, but due to the extreme low power leakage, they enable a longer lifetime with a smaller form factor.
Both use the same standard Bluetooth advertising packet discovery mechanism.
Bluetooth Beacon hardware devices are typically much larger even than conventional Bluetooth tags. They are stationary and are focused on marking a fixed location. They may plug into a power supply. As a result, they can broadcast more frequently and have a stronger signal that propagates further. Conventional beacons are typically configurable, whereas BAP devices are pre-programmed. A BAP will broadcast once every 4 seconds, a Beacon should broadcast 10 times a second. True Bluetooth Beacon hardware is by definition used to mark fixed Points of Interest or locations where that location needs to be received rapidly by readers.
BAPs can be used to mark a location; they will just take a little longer for a reader to register their presence.
