Data only updates once

All, I cannot seem to get my data to update more than once on the platform (note that the values are live/changing on the serial monitor).

I think I got it working now, for some reason I was under the assumption that you could not out any code in the void loop, not sure why I thought this ?

3

I’m glad that you solved the issue, for the next opportunity please post the code in the rigth format, it is easy for us to read and try to debug at first sight the issue you may have.

4

How do I post the code properly, did a very quick search and could not find

In the posting window, the button with the simbol “</>” is the one to give the code format, you may paste the whole sketch, select all of it, and press the button to give the appropriate format.
