Either network or requests module reboot the board

Hello guys,

I have encounter a problem trying to make a script that just checks the price for bitcoins the code is the following:

Code: Select all

from console import Display
import urequests
import json
import time
#import gc

oled = Display()

def ConnectWifi(SSID, pwd):
    Function to connect to WIFI.

        SSID: String with the name of the WIFI connection.
        pwd: String with the WiFi password.

    Returns: True if it's connected to wifi

    import network
    sta_if = network.WLAN(network.STA_IF)
    if not sta_if.isconnected():
        oled.clear(0, 1)
        oled.print_wrapped('Connecting to network...')
        sta_if.connect(SSID, pwd)
        while not sta_if.isconnected():

def GetTime():
    Get local time from the internet.

    Returns: Nothing

    import ntptime
    ts = time.localtime()
    year = ts[0]
    Month = ts[1]
    day = ts[2]
    hour = ts[3]
    mins = ts[4]
    dayYear = ts[7]
    ActualTime = "%s/%s/%s %s:%s" % (str(day), str(Month), str(year), str(hour), str(mins))
    return ActualTime

pwd = "SSIDPassword"

ConnectWifi(SSID, pwd)
while True:
    #print("Free out: " + str(gc.mem_free()))
    r = urequests.get("https://api.coindesk.com/v1/bpi/currentprice/EUR.json")
    Data = r.json()
    USD = Data["bpi"]["USD"]["rate_float"]
    EUR = Data["bpi"]["EUR"]["rate_float"]
    Date = Data["time"]["updated"]
    oled.clear(0, 1)
    oled.print_on_line("Price from %s" % Date.split(",")[0], 0)
    oled.print_on_line("USD: %s" % str(USD), 2)
    oled.print_on_line("EUR: %s" % str(EUR), 3)
The problems comes when executing the code:

Code: Select all

>>> import bitcoin_price

OSError: [Errno 2] ENOENT

MicroPython v1.9.4-8-ga9a3caad0 on 2018-05-11; ESP module with ESP8266
Type "help()" for more information.
The board automatically reboot and it seems to be coming either from the requests module or the network one, the weird part is that from the REPL the error is not reproduced:

Code: Select all

>>> import network
>>> import urequests
>>> sta_if = network.WLAN(network.STA_IF)
>>> sta_if.isconnected()
>>> r = urequests.get("https://api.coindesk.com/v1/bpi/currentprice/EUR.json")
>>> Data = r.json()
>>> Data

Anyone that could help me out here?
