First of all i would like to state that i am a noob at all of this and some of my words might not make sense so bear with me a bit.
The code that had to be uploaded to the nodemcu was stopped due to an error.

After this error i tried to get this code run on version 3.1.1 instead of 2.0.0. after that there was another error in the last quarter of the code.

Now to get proper understanding i tried chatgpt and corrected some codes there but still no luck.Another thing to mention is that i was not able to find Method 2 step 9(more prreferences) like it was specified
