Hi,
I would passively detect BLE devices (smartphone, smart-band, tag, …) even if they are already associated (paired) with each other.
I only need device ID and signal power.
Wireless iBeacon Receiver + “RAW” scan mode
is it enough to get this? Are there any limitations on the detectable BLE device type?
ABSniffer USB Dongle 528
is it a better alternative?
