Here is my setup, but so far I do not see messages at Linux or ESP end...
I am using the changes from here: #4
I confirmed that I can send/receive between two ESPs.

sudo apt install git python3-venv net-tools

git clone https://github.com/ChuckMash/ESPythoNOW.git
cd ESPythoNOW
python3 -m venv venv
source venv/bin/activate
pip install scapy
sudo bash prep.sh wlo2 8

# create sniff.py

cp venv/bin/python3 venv/bin/python_netraw
sudo chown $USER venv/bin/python_netraw
chmod -x,u+x venv/bin/python_netraw
sudo setcap cap_net_raw=eip venv/bin/python_netraw
python_netraw sniff.py

sniff.py

from ESPythoNOW import *
import time

def callback(from_mac, to_mac, msg):
  print("ESP-NOW message from %s to %s: %s" % (from_mac, to_mac, msg))

espnow = ESPythoNow(interface="wlo2", accept_all=True, callback=callback)
espnow.start()
print("running")
# input() # Run until enter is pressed

while True:
        msg=b'\x01\x10'
        espnow.send("08:d1:f9:54:00:cc", msg)
        time.sleep(3)

I assume this is micropython on the ESP side?
You may need to set the WiFi channel to channel 8 on the ESP, since it was specified with prep.sh on the Linux side.

Yes, this is MP on ESP side.

I set channel to 8, and ESP<->ESP is OK, but ESP<->Linux shows no data.

ESP1

import network
import espnow

_esp_now_peer = b'\x34\x7d\xf6\xb5\x6f\xa3'

sta = network.WLAN(network.STA_IF)
sta.active(True)
sta.disconnect()
sta.config(channel=8)
now = espnow.ESPNow()
now.active(True)
now.add_peer(_esp_now_peer)
now.send(_esp_now_peer, "hello from SHARC")
print('espnow: hello sent to peer')

while True:
  host, msg = now.recv()
  if msg:
    print(f'espnow: received {msg} from {host}')

ESP2

import network
import espnow
import utime as time

# _esp_now_peer = b'\x34\x7d\xf6\xb5\x6f\xa3'
_esp_now_peer = b'\xff\xff\xff\xff\xff\xff'

sta = network.WLAN(network.STA_IF)
sta.active(True)
sta.disconnect()
sta.config(channel=8)
now = espnow.ESPNow()
now.active(True)
now.add_peer(_esp_now_peer)


while True:
  host, msg = now.recv(0)
  if msg:
    print(f'espnow: received {msg} from {host}')

  now.send(_esp_now_peer, "hello from WALTER")
  time.sleep(1)

This is early on in the projects development, so bringing these issues up is very valuable, thank you.

Other things to consider:

Does the wlo2 chipset/driver support monitor mode?

Any output from prep.sh when you ran it?

Does scapy have root access to the interface? (could be https://stackoverflow.com/questions/44345689/sudo-scapy-not-working-on-virtualenv)

I am unfamiliar with ESP-NOW on micropython, maybe you could initially try simple_send_and_receive_ESP8266.ino or simple_send_and_receive_ESP32.ino

It appears that Intel 9560d2w does NOT support monitor based on Internet, but running iw does show monitor is supported. I will get an AR9271 adapter anyways.

Supported interface modes:
		 * IBSS
		 * managed
		 * AP
		 * AP/VLAN
		 * monitor
		 * P2P-client
		 * P2P-GO
		 * P2P-device

I do not know if scapy has root access to the interface. Would assigning CAP_NET_RAW have the same effect?
