When changing the code in events.c to also send the callback when in ASSOCIATING, it works perfectly. I'm a little bit worried of the side effects though. Anybody who knows what might go wrong?

I'm not sure I fully understood your description, but if you are saying
that you get disconnected even before association, there is no way of
knowing whether the PSK was correct or not. That warning is only shown
if the connection attempt fails during 4-way handshake. ASSOCIATING
state should only be used before 4-way handshake.
