Does ESP32 MP port implement AP password?

[paulg]

Hi,
Can anyone confirm whether or not the ESP32 MicroPython port implements the password when one creates an Access Point? The documentation suggests it does, but I have not been able together it to work. I copied the following code to main.py on my TinyPICO and pressed the Reset button.

Code: Select all

# Test program 9: Create a Wi-Fi Access Point with a password

import network
print('\nHello. This is test 9')
ap = network.WLAN(network.AP_IF)
ap.config(essid = 'esp32-test', password = '123456789')
ap.active(True)
print('Access Point created: ', ap.ifconfig())
print(ap.config('essid'), ap.config('channel'))
#print(ap.config('essid'), ap.config('channel'), ap.config('password'))
print('Goodbye!\n')

The result was:

Hello. This is test 9

Goodbye!

Scanning Wi-Fi networks on my phoned showed that esp32-test1 existed and was not protected.

If I uncomment the last but one print, I get:

Access Point created: ('192.168.4.1', '255.255.255.0', '192.168.4.1', '0.0.0.0')
esp32-test 1
Traceback (most recent call last):
File "main.py", line 12, in <module>
ValueError: unknown config param

This suggests to me that password is not implemented.

The following code works for me on a TinyPICO with MicroPython v1.10-231-g673db939b-dirty. Reading out the password seems to be prohibited, but setting it works.

Code: Select all

import network
import time
ap = network.WLAN(network.AP_IF)
ap.active(True)
import ubinascii
essid = b"MicroPython-%s" % ubinascii.hexlify(ap.config("mac")[-3:])
password = b"micropythoN"
for i in range(8):
	time.sleep(0.1)
	if ap.active():
		break
ap.config(essid=essid, authmode=network.AUTH_WPA_WPA2_PSK, password=password, hidden=False)
print('pass:{:s}\nname:{:s}'.format(password, essid))

Yes, the important detail is setting "authmode=network.AUTH_WPA_WPA2_PSK" in addition to the password.

Thanks Christian and Jimmo. Most helpful.

I doubt I would have worked that out as none of the examples I had seen mentioned authmode.
