Is it possible to see all the traffic of neighboring bluetooth devices using a regular usb dongle?

Question

Bluetooth

Good afternoon,
1. Tell me, can I get / see all the traffic of bluetooth devices located near me using hcidump or the same tcpdump using a regular usb dong? I tried to use the two dongles I have, but as a result I always saw only traffic addressed to my hciX interface.
2. Is it possible, by analogy with wifi, to translate my bluetooth interface into 'monitor mode' ? Collect and send packages yourself using the same scapy or another framework?
3. Googling, I realized that everyone praises Nordic chips, but I still could not understand what exactly are their advantages when working with bluetooth? Almost always the model appears everywhere: nrf24I understand this is the cheapest chip from this manufacturer, which is used for radio transmission by arduino lovers at a frequency of 2.4Ghz. Further, I found that it was based on it that the crazyradio usb dongle was built (which is used for sniffing wireless mice and keyboards) and here it becomes not entirely clear to me, it turns out that with only one usb dongle built on the nrf24 chip, it can be made to work with any protocol stack, whether Is it bluetooth or a protocol for wireless keyboards / mice, or in theory even wifi?
PS: I would be glad if someone in the topic explains it in an accessible way.
