Your help will be appreciated.

If you have not purchased a ThingSpeak license, your maximum update rate is once every 15 seconds. I do not see where you are limiting your code to make updates every 15 seconds or less. This is likely why your device is unable to post updates to ThingSpeak.

I didn't purchase a ThingSpeak License. I am using the free version
