Get request error

Need Help With My Project
1

I am making get requests in my program. If the ESP32 is not connected to the Blynk server, everything works fine, but as soon as it connects to Blynk, get requests do not work.

I am working with the ESP32 and Micropython. Below is the code and the errors I am getting.

import machine
import time

import BlynkLib     # https://github.com/vshymanskyy/blynk-library-python/blob/master/examples/03_sync_virtual.py
from BlynkTimer import BlynkTimer
import network

import urequests as requests

BLYNK_AUTH = 'VeGkFg63Yi23wrwAUDctKaAjZgUC'
TIEMPO_ESPERAR_CONEXION_WIFI=25

wifi = network.WLAN(network.STA_IF)
wifi.active(True)
wifi.connect("INFINITU242_2.4","CNC917MDE")

tiempoInicialPeriodo = time.time()
while not wifi.isconnected() and time.time()-tiempoInicialPeriodo<TIEMPO_ESPERAR_CONEXION_WIFI:
  time.sleep(5)
print('WiFi IP:', wifi.ifconfig()[0])

data = requests.get(url='https://api.open-meteo.com/v1/forecast?latitude=22.28519&longitude=-97.87777&current=temperature_2m').text
print("Here 1 -OK: ",data)

print("Connecting to Blynk server...")
blynk = BlynkLib.Blynk(BLYNK_AUTH,server="ny3.blynk.cloud")

data = requests.get(url='https://api.open-meteo.com/v1/forecast?latitude=22.28519&longitude=-97.87777&current=temperature_2m').text
print("Here 2 -Error: ",data)

Here is the program and output without using Blynk:

wifi.disconnect()

The output is fine.

Does the device connect to Blynk correctly if you don’t make the API call?

Pete.

3

Yes.

You might be better using a Webhook from within Blynk to get your open metro data.

I am going to try. Thank you.
