esp2866 restart couldn't stop

[vidalouiswang]

`
def init():
import net
if net.connect('ssid', 'password'):
print("ok")

init()
`
After running this code, esp8266 will reboot itself(hard reset) won't stop.

net.py:
`
import network
def connect(ssid,password=None):
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
import machine
a = scan(ssid)
if a:
wlan.connect(ssid, password)
while not wlan.isconnected():
machine.idle()
return True

def scan(ssid=None):
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
if ssid:
a = wlan.scan()
for i in a:
if i[0] == bytes(ssid,"ascii"):
return i
else:
return wlan.scan()
`
Need to erase and flash firmware in esptool will recover.

Codes in net.py almost from offical examples.

I also tried these simple code:
'
import network
import machine
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("ssid", "password")
wlan.isconnected()
`

Here is the result:

`MicroPython v1.14 on 2021-02-02; ESP module with ESP8266

Type "help()" for more information.

import network
import machine
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
#7 ets_task(4020ee68, 28, 3fff9e90, 10)
wlan.connect("ssid", "password")
wlan.isconnected()
True

Seems it will restart after connected to AP.

Run same code, it recovered itself(won't restart again), I do nothing before that, only unpluged in the board from the cable for about 2mins.

I suggest you raise this support query in the forum rather than in the MicroPython bug tracker.

Okay, thank you.
