ESPythoNOW

Linux based Python ESP-NOW library

Send and receive ESP-NOW messages to and from a Linux machine and ESP8266/ESP32 devices
Monitor all ESP-NOW messages
Work In Progress

Prep the interface and set channel

sudo bash prep.sh wlp1s0 8

Send and Recieve ESP-NOW messages

from ESPythoNOW import *

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

espnow = ESPythoNow(interface="wlp1s0", mac="48:55:19:00:00:55", callback=callback)
espnow.start()

while True:
  msg=b'\x01'
  espnow.send("48:55:19:00:00:33", msg)
  time.sleep(3)

Monitor all ESP-NOW Traffic

from ESPythoNOW import *

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

espnow = ESPythoNow(interface="wlp1s0", mac="48:55:19:00:00:55", accept_all=True, callback=callback)
espnow.start()
input() # Run until enter is pressed

NOTE about current state, subject to change or improvments

Interface must support monitor mode
Any "local" MAC address is supported, does not need to match actual local MAC
Does not send delivery confirmation, so an ESP based device sending messages to ESPythoNOW will not have a confirmed delivery
Does not retry transmission, or detect delivery confirmation
Does not support ESP-NOW encryption
