below code works for me using M5Stack Basic or Fire (running UIFlow firmware 1.12.3):

from m5stack import *
from m5ui import *
from uiflow import *
import module

setScreenColor(0x222222)

lan = module.get(module.LANBASE)

label0 = M5TextBox(21, 24, "label0", lcd.FONT_Default, 0xFFFFFF, rotate=0)
label1 = M5TextBox(22, 58, "label1", lcd.FONT_Default, 0xFFFFFF, rotate=0)

label0.setText('Hello 1')
lan.tcp_udp_config('192.168.144.1', 4711, 1, 2)
label0.setText('Hello 2')
label1.setText(str(lan.get_if_config()))
lan.tcp_send_packet('1234')
label0.setText('Hello 3')
lan.socket_close()
label0.setText('Hello 4')

Thanks

I haven't tried with "CircuitPython" this is (normally) maintained by Adafruit.
One problem with CircuitPython compared to micopython is it has no support for threads.
Later I want to add a watchdog (when I can communicate) and it will not function without multithreading...

any reason you did not try the provided UIFlow blocks under Modules - LAN Base?

BTW: I just found out that MicroPython is not the same as CircuitPython (and I think both are different from UIFlow).

Thanks

I was considering purchasing the "ATOM PoE Kit with W5500", but I suspect I might encounter the same issues.

The idea of stacking modules on top of each other is brilliant. I'll check back in the future to see if they've transitioned to open source or if the issues have been resolved...

from machine import Pin,SPI
from libs.ethernet.wiznet5k import WIZNET5K
import libs.ethernet.wiznet5k_socket as socket
import time
import module
import LAN.wiznet5k_requests as requests
#Server
ServerIP = '192.168.0.100'
ServerSub = '255.255.255.0'
ServerRouter = '192.168.0.254'
ServerDNS = '192.168.0.254'
def cnvIP(inIP):
stripIP = inIP.strip()
splitIP = stripIP.split('.')
outIP = tuple(int(x) for x in splitIP)
return(outIP)
nic = WIZNET5K(is_dhcp=False)
time.sleep(1)
nic.ifconfig = (cnvIP(ServerIP),cnvIP(ServerSub),cnvIP(ServerRouter),cnvIP(ServerDNS))
requests.set_socket(socket, nic)
time.sleep(1)
MAC = ''.join(['{:02x}'.format(b) for b in nic.mac_address])
print("macaddress: " + MAC)

I've made som improvment to get rid of the "requests" module but I stuck with the socket communication. I can ping the address (192.168.0.100)

#----> code snippet from socket communication--> I get stuck on the "recv" function. I've tried to reduce to 128 byte (prev. 2048) and I know my client is OK. But I get no error message...

u = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
u.bind((ServerIP, Port))
tcp1_conn, tcp1_addr = u.accept()
data = tcp1_conn.recv(128)

from libs.ethernet.wiznet5k import WIZNET5K
import libs.ethernet.wiznet5k_socket as socket
import time

#Server
ServerIP = '192.168.0.100'
ServerSub = '255.255.255.0'
ServerRouter = '192.168.0.254'
ServerDNS = '192.168.0.254'
Port = 5465

def cnvIP(inIP):
stripIP = inIP.strip()
splitIP = stripIP.split('.')
outIP = tuple(int(x) for x in splitIP)
return(outIP)

nic = WIZNET5K(is_dhcp=False)
time.sleep(1)
nic.ifconfig = (cnvIP(ServerIP),cnvIP(ServerSub),cnvIP(ServerRouter),cnvIP(ServerDNS))
socket._the_interface = nic
time.sleep(1)
MAC = ''.join(['{:02x}'.format(b) for b in nic.mac_address])
print("macaddress: " + MAC)

The rest is socket communication --->
