OSError: [Errno 103] ECONNABORTED

[Javier96Barrera]

Hi, I'm quite new to micropython. I have flashed the 1.9.2 version on my Lolin v3 (Nodemcu 12e). I load the code using ampy command, then open terminal with Putty, and reset the board. i get this error while trying to use the sentence "connect()":

Traceback (most recent call last): File "main.py", line 44, in File "umqtt/simple.py", line 56, in connect OSError: [Errno 103] ECONNABORTED

MicroPython v1.9.2-8-gbf8f45cf on 2017-08-23; ESP module with ESP8266

    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print('connecting to network...')
        wlan.connect('SSID', 'PASSWORD')
        while not wlan.isconnected():
            pass
    print('network config:', wlan.ifconfig())

Thanks for your time, if there is any problem regarding the information or post structure, tell me and I will try to fix it.

This github issue tracker is mainly for bug reports and code improvements. The report here is more of a problem using the libraries, and help in this area is best asked at https://forum.micropython.org. So please try to ask your question there (or maybe someone had the same issue and already fixed it).

Otherwise, the general thing to try is to verify you have internet connectivity, eg:

>>> import socket
>>> socket.getaddrinfo('micropython.org', 80)
