code is working but data is not receiving at thingspeak

My code is working properly but i am not recevind the data at thingspeak if i can get any help ?? here is the code

#include <SoftwareSerial.h>

}

I would look at the examples in the ThingSpeak library, which you are using. Try hardcoding a value to send to ThingSpeak, to remove issues of the sensors.

I would not use a static ip, and you also have that line commented out, so I dont think the code you shared ywould compile.

If you are still stuck after simplifying, make sure you share what you have tried and what you see on the serial monitor.

Any luck using the examples?

Nup 😔

Does this answer help?

No

[Christopher Stapels]

What happened when you tried the commands in that example? Can you show the output?

Same problem for me also with python program.

import paho.mqtt.publish as publish
import time
import random

server = "mqtt.thingsepak.com"
port = 1883

channel_id = "xxxxxxxxxxxxxx"
write_api_key = "xxxxxxxxxxx"
topic = "channels/"+channel_id+"/publish/"+write_api_key
mqtt_username = 'xxxxxxxxx'
mqtt_password = 'xxxxxxxxxxxxxx'

mqtt_auth = { 'username': mqtt_username, 'password': mqtt_password }

while True:
    h = random.randint(30,100)
    t = random.randint(10,50)
    data = "field1="+str(t)+"&field2="+str(h)
    publish.single(topic, data, qos=0, retain=False, hostname=server,
    port=port, client_id=mqtt_username, keepalive=60, will=None, auth=mqtt_auth,
    tls=None)
    time.sleep(15)

Your code needs to be updated. Start with the example here. For starters, your server is incorrect: "mqtt.thingsepak.com" would never have worked.
