Hi Thomas, We implemented your tests, but still got a hard fault.
Strangely, though, if we put at86rf231_switch_to_rx right after at86rf231_send, the crash is gone; we haven't checked if sending and receiving actually works, but at least it's not crashing anymore. It looks a bit hacky to me, but I don't know if it should indeed be done that way...
