I have no idea what a mymobiler device is, nor how you would go about
using Python with it.

So send 224 followed by 80?
Or maybe construct a byte string using the struct module and send that?

Given we have no idea what you are doing to "send" the data we can only
make wild guesses as to what might be happening.
It might help if you posted on a mymobiler specific forum? Or maybe the
main python list, since this is not really about learning Python, more
about learning how to communicate with your device.
But as a minimum, provide a lot more context and at least some code.
