I would like to use my M5Stack as a http Server. That works great with internal WiFi, but not via Ethernet.
The solution is programmed in Micropython.

The following code does not work on my M5Stack Fire with W5500 Base Module:
--> line 4: in <module> AttributeError: 'module' object has no attribute 'LAN'

import network
import socket

lan = network.LAN(mdc=23, mdio=18, power=21, phy_type=network.PHY_W5500, phy_addr=0)

lan.ifconfig(('192.168.50.108', '255.255.255.0', '192.168.50.1', '255.255.255.0'))
lan.active(True)

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('192.168.50.108', 8080))

sock.listen(1)
while True:
conn, addr = sock.accept()
print('Connection from:', addr)
conn.sendall('Hello, world!')
conn.close()

tried with modified code, but no luck:

from m5stack import *
from m5ui import *
from uiflow import *
import wifiCfg
import network
import socket
import module

#WiFi
wifiCfg.screenShow()
wifiCfg.autoConnect(lcdShow=True)
wifiIp = wifiCfg.wlan_sta.ifconfig()[0]
title0 = M5Title(title="SERVER-EXAMPLE", x=95, fgcolor=0xFFFFFF, bgcolor=0xff001d)
label0 = M5TextBox(10, 40, "WiFi ip :" + str(wifiIp), lcd.FONT_Ubuntu, 0xfff500, rotate=0)

counter = 0

#Ethernet
lan = module.get(module.LANBASE)
eth0Ip = lan.get_if_config()[0]
label1 = M5TextBox(10, 60, "Eth0 ip :" + str(eth0Ip), lcd.FONT_Ubuntu, 0xfff500, rotate=0)
lan.tcp_udp_config(eth0Ip, 80, 1, 1) ## es muss ein call gemacht werden, damit das Programm weiter läuft

#Choose ip address
#ip = wifiIp # works
ip = eth0Ip # does not work

label2 = M5TextBox(10, 80, "SERVER is running", lcd.FONT_Ubuntu, 0xfff500, rotate=0)

label3 = M5TextBox(10, 100, "waiting...", lcd.FONT_Ubuntu, 0xfff500, rotate=0)
label4 = M5TextBox(10, 120, "received?", lcd.FONT_Ubuntu, 0xfff500, rotate=0)

if ip == wifiIp:

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server.settimeout(30)
server.bind((wifiIp, 80))

while True:
    server.listen(1)
    
    (conn, addr) = server.accept()
    request = conn.recv(4096)

    if request:
        counter = counter + 1
        request = str(request)
        conn, addr = server.accept()
        label3.setText(str(counter))
        label4.setText(str(request))
        response = 'Hello, world!'
        conn.sendall(response)
        conn.close()

    wait_ms(2)

if ip == eth0Ip:

while True:
    if lan.is_available_packet(1):
        counter = counter + 1
        request = str(lan.tcp_receive_packet(0))
        label3.setText(str(counter))
        label4.setText(str(request))
        response = 'Hello, world!'
        lan.tcp_send_packet(response)

    wait_ms(2)

Hi felmue
Thanks for your appreciated reply.
Unfortunately it is unusable for me in that way. I would like to bind the ip address to a socket on port 80 (http server). And I dont want that the application is blocked until a client connects.
best regards

Sorry for the late reply. I simply put in the sim card the wrong way LOL. The 45° edge must be on the outside. Shame on me And of course the pins of the module are very, very short.

Hi friends

I have written a simply micropython test program as a web server.
It works when I am using the configured ip address of wifi connection (ip via dhcp).
Then I have tried the LAN base module W5500 V12.
Unfortunately it does not work with the configured ip address of the ethernet module (ip via dhcp) .

I have used....
lan = module.get(module.LANBASE)
...instead of...
lan = network.LAN(mdc=23, mdio=18, power=21, phy_type=network.PHY_W5500, phy_addr=0)
lan.active(True)
...because I get an error message that network does not support LAN methode.

Here is my micropython example code:

from m5stack import *
from m5ui import *
from uiflow import *
import wifiCfg
import network
import socket
import module

#WiFi
wifiCfg.screenShow()
wifiCfg.autoConnect(lcdShow=True)
wifiIp = wifiCfg.wlan_sta.ifconfig()[0]
title0 = M5Title(title="SERVER-EXAMPLE", x=95, fgcolor=0xFFFFFF, bgcolor=0xff001d)
label0 = M5TextBox(10, 40, "WiFi ip :" + str(wifiIp), lcd.FONT_Ubuntu, 0xfff500, rotate=0)

#Ethernet
lan = module.get(module.LANBASE)
#lan = network.LAN(mdc=23, mdio=18, power=21, phy_type=network.PHY_W5500, phy_addr=0)
#lan.active(True)
eth0Ip = lan.get_if_config()[0]
label1 = M5TextBox(10, 60, "Eth0 ip :" + str(eth0Ip), lcd.FONT_Ubuntu, 0xfff500, rotate=0)

#Choose ip address
ip = wifiIp # works
#ip = eth0Ip # does not work

#Socket binding
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((ip, 80))

label2 = M5TextBox(10, 80, "SERVER running at " + ip, lcd.FONT_Ubuntu, 0xfff500, rotate=0)

#Listening
sock.listen(1)
while True:
conn, addr = sock.accept()
print('Connection from:', addr)
conn.sendall('Hello, world!')
conn.close()

Hi folks
Is there any tutorial or example to send SMS via a COM.X LTE Module in UIFlow or Python
I have a SIM card of TalkTalk with deactivated PIN code.
But I have no luck to get it to work.
Thank you for your help.
Best regards

I have no clue why this happens. Does no one use the TF-sensor for such "long" time without restart?

New findings:
The TF-sensor readings "hangs" exactly after 13 days.
After that always the same value is given out.
This behavior was occured every 13 days in the last 5 months.
Very strange.
What could that be?

Hi folks

I have a program that reads the TF sensor every second.
After 1 or 2 weeks, the sensor suddenly only delivers the same constant value (last value read from it).
I have to restart the whole device and then the sensor does read out correct current values again for 1 or 2 weeks.

example (values only to visualize with some fault measurement like in real):
99.7, 99.6, 99.7, 98.9, 98.8, 98.5, 98.3, 98.4, 98.3, 97.9, 97.6, 97.2, 97.3, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7

Does anyone know the problem?
