Do you have firmware code that reproduces the problem available somewhere? Or at least information as to what you're writing and how big the buffer is?

Welp, that's a bug. Seems I broke writing long messages while implementing the other blocking modes. Found a fix already, will take a look at releasing it soon.

I'm adding a couple of other things in the process, stand by!
