> Sounds good. I assume RF_CONFIRM and RF_INDICATION are groups of events, rather than that only the two event values are used?

Exactly. They are mapped to an internal event after calling the `irq_handler`.

> For RF_CONFIRM the advantage of having e.g. RF_CONFIRM_IDLE, RF_CONFIRM_CCA, etc. might not be so huge, but at least these two:

What I was thinking here is that these states (RF_CONFIRM_IDLE, RF_CONFIRM_CCA) can be generated by the `irq_handler` (so always in thread context). the `RF_CONFIRM` and `RF_INDICATION` are only interrupts that tell the upper layer "to call the irq_handler ASAP" but also adds the possibility of using mutex for indications and event queues for indications
