Having looked at your App and the Arduino Sketch, I cannot see anything matching this description. The Arduino Sketch is very complex, with an unusual number of delays. However, there is a lot of Serial reporting to the Arduino Serial Monitor so you should be able to see the root of the problem.
What, exactly, is the error message?
Also, can you explain your process Lazrag - you have not shown all your Blocks.
I see it as: Arduino --> ThingSpeak --> App? The data appears to be sent very frequently. Normally we see this type of App using large intervals of time.
If you are going to distribute your App, be aware that ThingSpeak is expensive. If the App is presenting the data, ThingSpeak's ability to present data is not required.
