However based on warnings about high resource use when scanning for Bluetooth and the high probability that a Bluetooth device will be mobile that has not been implemented.
Bluetooth beacons are more likely to be stationary, and useful for positioning.
If the concern re scanning is power usage, then make scanning conditional:
when externally powered (mains charger or external battery)
when the position hasn't changed much (<50 metres in 30 minutes?) perform a background scan — this should more likely capture places the user cares about, be inside buildings, and avoid scanning while travelling
