Mode STA...no work

[madeskjet]

Impossible!

NodeMCU Amica V1.0
MicroPython v1.12 on 2019-12-20; ESP module with ESP8266

Code: Select all

import machine 
import network  
import time     

led = machine.Pin(16, machine.Pin.OUT) 

led.value(0)

print ("LED Encendido")

sta_if = network.WLAN(network.STA_IF)
ap_if = network.WLAN(network.AP_IF) 

if (ap_if.active()): 
	if (ap_if.active()):
    		ap_if.active(False)

if not sta_if.isconnected():
    print ("Conectando a la red WiFi")
    sta_if.active(True) 
    sta_if.connect('SSID','PASS')
    while not sta_if.isconnected():
                pass
    print ("Conectado!")

print ("Configuracion de red: ", sta_if.ifconfig())

I tried different AP, with/without security...

What happen?

Busy waiting is sometimes a problem. Try:

Code: Select all

import machine 
import network  
import time     

led = machine.Pin(16, machine.Pin.OUT) 

led.value(0)

print ("LED Encendido")

sta_if = network.WLAN(network.STA_IF)
ap_if = network.WLAN(network.AP_IF) 

if (ap_if.active()): 
    ap_if.active(False)

if not sta_if.isconnected():
    print ("Conectando a la red WiFi")
    sta_if.active(True) 
    sta_if.connect('SSID','PASS')
    while not sta_if.isconnected():
        time.sleep(0.2)
    print ("Conectado!")

print ("Configuracion de red: ", sta_if.ifconfig())

[madeskjet]

Yes! I do it!

Thanks!

You MUST put a delay between defining your sta and ap like:

Code: Select all

sta_if = network.WLAN(network.STA_IF)
time.sleep(0.1)  # <---- IMPORTANT
ap_if = network.WLAN(network.AP_IF) 

Then it will work

Works! Just one time...
Upload again main.py and...not works.

I don´t get it.

The ESP8266 will remember the WiFi status between reboots. So if you have disabled AP once, you do not have to repeat that.
I'm personally using STA mode since the ESP8266 port exists w/o problems. The connect code is called from main.py.

@madeskjet , did you read my post?
You have you put time.sleep(0.1) as I suggested because that is the problem.

Edit:
Maybe it is neccessary to put de delay after "sta_if.active(True)"

Anyway it 100% is a (reproducable) bug in either Micropython (or in de SDK of Espressif) which I mentioned already in viewtopic.php?f=16&t=7577

Another Micropython firmware w/o bugs?
Thanks

sometimes it takes longer to (re-)connect.
and having then only a "one-flow" logic doesnt work then.

have a look here at the base modules (wlan, softap, and ntp modules)
which does it in a "loop" manner (the impl keeps an eye on state)
