wifi connect regression-tester

code.py

import os, time, wifi, socketpool
from secrets import secrets

SLEEP = 1

pool = socketpool.SocketPool(wifi.radio)

def connect():
    try:
        wifi.radio.connect(secrets['ssid'], secrets['password'])
    except ConnectionError as e:
        print("Connection Error:", e)

while True:
    print(f"Connecting... ", end="")
    wifi.radio.enabled = True
    connect()
    print(f"{wifi.radio.ipv4_address} ", end="")
    if "2040" in os.uname().machine:
        time.sleep(0.100)  # sometimes needed for connection to complete
    else:
        print(f"RSSI={wifi.radio.ap_info.rssi} ", end="")  # NotImplementedError
    time.sleep(SLEEP)

    print(f"Disconnecting... ")
    wifi.radio.enabled = False
    time.sleep(SLEEP)

Occasional Connection Error: Unknown failure with various numbers are fine, but they should be infrequent.

Error codes and their meanings are here (my git blame from two years ago):

Added delay for raspberrypi: wifi.radio.connect and wifi.radio.ipv4_address are slightly decoupled in this port.
