this is working for me for talking with simple servers using the esp. Its of course
limited and it will break on interactive sessions i.e those that refresh the screen.
I post it because when I first joined i really wanted to find such code and never was able to.
Corrections / improvements welcome, I was unable to make it keypress-based for example.

Code: Select all

import socket
import time
import gc
def start():
    serv = input("Servidor:\r\n")
    porta = input("porta:\r\n")
    addr_info = socket.getaddrinfo(serv, int(porta))
    addr = addr_info[0][-1]
    del serv
    del porta
    s = socket.socket()

    del addr
    del addr_info
    d = "."
    while d:
      d = s.recv(500)
      print (str(d, 'utf8'))
     except OSError:
      i = input()
      i = i + ("\n")
    print("\r\n\r\nExecution finie\r\n")
    del s
    del i
    del d

There is a telnet server made by @chrisgp, which was made for ESP8266, but should also work on the recent firmware version of the ESP32.

Hi Roberthh, thanks, but this is an attempt to build a client, not a server! It's not for connecting to the Esp over wifi; it's to connect from the ESP to other sites/servers.
