I have post lost of examples, and there should be examples in the library examples. I'm not using the 411 so no idea if there is anything special with that, and you're not providing any code to give some insight into why you've been unsuccessful.

I'll note you need to disable the TXE interrupt if you have not data to provide, otherwise it will never exit the interrupt handler.
