Hi Enzo.
Did you try the original code?
I’ve just run the code and it is working as expected.
I recommend reflash your board with micropython firmware and try again.

Hi Sara,
thanks, I’ll try to reflash but if I set it up as a station (client) it works fine and so for all other code I’m writing so I don’t think it’s a firmware issue.
However I need to write some different code so I need to understand what’s the issue about this.
I’ve a station setup in my boot code: maybe this is the problem? I tried setting

station.active(False) 

before setting

network.WLAN(network.AP_IF)

but it gave the same error.

UPDATE: I made some tries and this is what I got:
when I flash the ESP with fresh new MicroPython 1.13 it has only a basic boot in it:

# This file is executed on every boot (including wake-boot from deepsleep)
#import esp
#esp.osdebug(None)
import uos, machine
#uos.dupterm(None, 1) # disable REPL on UART(0)
import gc
#import webrepl
#webrepl.start()
gc.collect()

but neverthless it starts a wifi network “MicroPython-c64376” and pw unknown (???). Do you know why and what’s the default password it sets?
However my fault seems to be that I tried to re-assign the same variable name to the network.WLAN instance: if Iset the active ap instance to False and create  a new one with a different name it works.
I need further experimenting to be sure of this. I’ll let you know what I find!

Hi.
Current releases of MicroPython have the access point interface enabled by default. The default password for this connection is micropythoN.

Hi Sara,
this code at first sets up the ESP as an AP and after sets it up as a client of the home wifi net:

def createAP(ssid, pw):
    ap = network.WLAN(network.AP_IF)
    ap.active(True)
    ap.config(essid=ssid, password=pw)
    while ap.active() == False:
        pass
    return(ap)
def connect_to_wifi(SSID, PW):
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print("Connecting to network...")
        wlan.connect(SSID, PW)
        while not wlan.isconnected():
            pass
    print('Connection successful')
    mac = ubinascii.hexlify(network.WLAN().config('mac'),':').decode()
    return(wlan.ifconfig())
ap = createAP(ssid, pw)
print(ap.ifconfig())
a = input("Close AP?")
client_config = connect_to_wifi(SSID, PW)
print(client_config)
ap.active(False)

Do you know why it sends this output:

bcn 0
del if1
pm open,type:2 0
mode : sta(8c:aa:b5:c6:43:76)

after I set the AP to false because I don’t need it anymore?
Thanks.
Best regards.

Hi.
Unfortunately, I don’t know what it means.
Do you want to set access point and station at the same time?
Can you tell me why do you need access point at first? Just to better understand what you are trying to achieve.

Sara

Hi Sara,
I need to make my ESP an AP at first and then a station. I achieved it this way (sample code):

def createWifiAP(ssid, pw):
    ap = network.WLAN(network.AP_IF)
    ap.active(True)
    ap.config(essid=ssid, password=pw)
    while ap.active() == False:
        pass
    return(ap)

def connectToWifi(SSID, PW):
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
if not wlan.isconnected():
print(“Connecting to network…”)
wlan.connect(SSID, PW)
while not wlan.isconnected():
pass
print(‘Connection successful’)
mac = ubinascii.hexlify(network.WLAN().config(‘mac’),’:’).decode()
return(wlan.ifconfig())

ap = createWifiAP(ssid, pw)
print(ap.ifconfig())
a = input(“Close AP?”)
client_config = connectToWifi(SSID, PW)
print(client_config)
ap.active(False)

it works, I don’t understand why after setting inactive the AP instance it outputs this:

bcn 0
del if1
pm open,type:2 0
mode : sta(8c:aa:b5:c6:43:76)

Hi Enzo.
Thanks for sharing your code.
I also don’t know what that output means. I think it is some information about the wi-fi station.

Sara
