@ZENAR57 Did you get serial working in your development environment (APDE, Android only and no PC)?

I have now!  
I did this with Processing for Android (development on PC) to test the library.

I followed instructions on this site:

> **[GitHub - inventit/processing-android-serial: Android Serial Library for...](https://github.com/inventit/processing-android-serial)**
>
> Android Serial Library for Processing. Contribute to inventit/processing-android-serial development by creating an account on GitHub.

I got an OTG cable yesterday.

I wrote a very minimal sketch:

- Arduino Mega is is counting up and sending data every 500ms.
- Android is receiving and display count to the screen.

It is working!

I may try your approach in the future but not anytime soon. I am very busy these days.
