How do I receive actually sent IEEE 802.11 frames

[moshangqingfeng]

Dear all,
After learning 'nexmon.org/sdr' and 'nexmon.org/csi', I want to use two Raspberry PI 3B+ for sending and receiving, respectively.
I used a Raspberry PI to send the IEEE 802.11 beacon frame at 'nexmon.org/sdr', and on the receiving end I tried changing the mcp command: ' mcp-C 1-N 1-c 1/20-m b8:27:eb:dc:ee:3f (this is my sent mac address),' but I can't receive it. I also tried changing the tcpdump command: ' tcpdump -i wlan0 ether src b8:27:eb:dc:ee:3f', but that too failed.
How should I configure the receiving end to receive the beacon frame from the sending end?
