Sniff/Detect/Track BLE paired devices like smartphone and smartband

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?

Sorry. I think Receiver and ABSniffer 528 can’t do this job both.

:sob:

what can i detect with Wireless iBeacon Receiver + “RAW” scan mode?
peripherals that are not necessarily beacon?

thanks for the answers…

These products can only detect advertising data from BLE devices nearby. can’t get data when they are connected.
