Hello Everyone! I'm trying to post data from my BME280 sensor to my websites API which worked absolutely fine with c++ but i can't seem to nail it with MP

error

Code: Select all

>>> 
Full code, The Sensor on it's own works absolutely fine, the Wifi Works checked by using station.isconnected()

Code: Select all

from machine import Pin, I2C
from time import sleep
import network
import BME280
import urequests

# ESP32 - Pin assignment
i2c = I2C(scl=Pin(22), sda=Pin(21), freq=10000)

station = network.WLAN(network.STA_IF)
station.active(True)
station.connect("...", "...")

logger = "http://reep.com/api"

while True:
  bme = BME280.BME280(i2c=i2c)
  temp = bme.temperature
  hum = bme.humidity
  pres = bme.pressure
  # uncomment for temperature in Fahrenheit
  #temp = (bme.read_temperature()/100) * (9/5) + 32
  #temp = str(round(temp, 2)) + 'F'
  print('Temperature: ', temp)
  print('Humidity: ', hum)
  print('Pressure: ', pres)
  
  url = logger+"?temperature="+str(temp)+"&humidity="+str(hum)

    print ("url: "+url)

    response = urequests.get(url)

    response.close()

    time.sleep(60)


  sleep(5)

What error do you get?

I don't know if it's an issue with copying into the forum but the indentation is wrong for everything from the print(url...) line onwards.

Sorry I don't follow - the code you posted wouldn't print that output?

I'm not sure what's going on either. Here's the latest error after trying to run the code

Code: Select all

station = network.WLAN(network.STA_IF)
station.active(True)
station.connect("ssid", "password")

logger = "http://website.com/api"

while True:
  bme = BME280.BME280(i2c=i2c)

  url = logger+"?temperature="+str(temp)+"&humidity="+str(hum)

  print ("url: "+url)

  response = urequests.get(url)

  response.close()

I think somethings going wrong with the way you're copying the files to the device -- it doesn't look like your main,py is actually running. (Are you using an IDE that's responsible for that exec() line?) I've seen a few people with this issue on the forum...and it always involves this exec(open('main.py'...) etc.

Can you try using pyboard.py [1] or rshell [2] or ampy [3]

[1] https://github.com/micropython/micropyt ... pyboard.py
[2] https://github.com/dhylands/rshell
[3] https://github.com/scientifichackers/ampy

I personally use pyboard.py -- my workflow is either:

Code: Select all

$ pyboard.py --device <device> filename.py
(which will run filename.py on the device and print any output)

or

Code: Select all

$ pyboard.py --device <device> -f cp main.py :main.py
(then connect with a serial terminal, hit ctrl-d to soft reset)
