It's collecting moisture readings and then sending them to a Adafruit IO feed through a POST. I found my way around th 113 errors from urequests, but now I'm getting OSerror 118. I guess this indicates the wifi isn't connected.

I'm using wifiCfg's doConnect function in a while loop in hopes that it will keep trying until it works. This works on an initial run, but it looks like it fails after a lightsleep.

Does anyone have any idea about how I can get the wifi to connect more reliably? What am I missing?

while(True):
  gc.collect()
  while not wifiCfg.doConnect('guest', '12345678', lcdShow=True): pass

  lcd.clear()
  lcd.setTextColor(0xaaaaaa, lcd.BLACK)
  lcd.font(lcd.FONT_DejaVu18)
  axp.setLcdBrightness(50)
  
  test.display(int(get_moisture()/10))
  wait(2)

  moisture = get_moisture() #get moisture
  try:
    response = urequests.request(
      method='POST',
      url='http://io.adafruit.com/api/v2/********/feeds/moisture/data',
      json={'value':moisture},
      headers={'Content-Type':'application/json','X-AIO-Key':'**************************'}
    )
    if response.status_code == 200:
      led.duty(99)
      lcd.clear()
      lcd.print("sent", lcd.CENTER, 5)
      lcd.image(0, 50, 'img/success.jpg')
      wait(1)
      axp.setLDO2Volt(0)
    else:
      lcd.print("request \r\n error", lcd.CENTER, 0, 0xFFFFFF)
      lcd.image(0, 50, 'img/error.jpg')
      led.duty(50)
      wait(10)
  except Exception as e:
    lcd.print("OS error", lcd.CENTER, 0, 0xFFFFFF)
    lcd.image(0, 50, 'img/error.jpg')
    print(e)
  
  gc.collect()
