Micropython ESPNow Utilities

A collection of small utilities for use with espnow and wifi on micropython

src/wifi.py: A small module to bulletproof initialising wifi on ESP32 and ESP8266 devices.

These functions are designed to robustly and reliably account for differences between esp8266 and esp32 devices and to ensure the wifi is always in a fully known state (even after soft_reset).

import wifi

sta, ap = wifi.reset()   # STA_IF on and disconnected, AP off, channel=1
sta, ap = wifi.reset(sta=True, ap=True, channel=6)
wifi.connect("ssid", "password")
wifi.status()            # Print details on wifi config

src/espnow_scan.py: Scan channels to find an ESPNow peer.

import espnow_scan

espnow_scan.scan(e, b'macadd')  # Print channel if found and leave set to channel

src/lazyespnow.py: LazyESPNow() extends ESPNow class to catch and fix most common errors.

from lazyespnow import LazyESPNow

peer = b'\xaa\xaa\xaa\xaa\xaa\xaa'
enow = LazyESPNow()
enow.send(peer, message)    # Automatically call active(True) and add_peer()

src/ntp.py: Set the time from an NTP server over wifi.

import ntp
ntp.server = "192.168.1.1"
ntp.settime()

src/timer.py: A useful collection of easy to user python timer objects.

import timer

for t in timer_ms(5000, 1000, raise_on_timeout=True):
    print(t)

src/echo.py: A simple ESPNow server that echos messages back to the sender.

import echo

echo.server()       # Wait for incoming messages and echo back to sender
