Yeah, figured, it is possible but I lack the expertise, however I found that you need to have su privilages for the app, which is impossible to provide in these devices , they are closed source and very little documentation is available from manufacturer, I even tried adb and all other ways (tried rooting too, but failed misearbly),somehow, accesing the serial port via termux is possible,even tried background terminal process)(too slow for me),
Later I found a plugin called SPUP ,a uart bridge approach(my last resort), but it is smart and can adapt to all platforms without any code changes,which hopefully worked

So the problem is currently solved, but still open to suggestion and alternatives.
Thanks
