It is not clear to me, what is the main differences between these two beacons.
ABKey01 has accelerometer also? Does it have different modes (like Sensor, Motion)? Does it always broadcast or just when it moves (like ASensor in Motion mode)?
What is the purpose of the button on ABKey01? As I see when I push the button, it broadcasts an other iBeacon parameters. Is it true? If it is, the how can I turn of the device?
