The key length is indeed limited to 16 bytes or less when connecting manually. It's an unfortunate limitation, but the way TI defined the struct for the connection params, the didn't leave room for more bytes than this. You can connect with up to a 32 byte key using SmartConnect, but normally not with a manual connection.
What method are you using to connect?

You can see a note on this from TI here in the doxygen comments:

After it wasn't working with manually connecting using .connectToAP(), I tried smart config and that wasn't working either. Then I made the change to the MAXLENGTHKEY = 32 and tried manually connecting again and it worked.
It might SAY "up to 16 bytes", but more than 16 works ;-) Might be worth asking them about it... because having long passwords is pretty common.

I'm using WPA security btw.

Confirmed with TI engineering staff that recent firmware can handle 32 chars max now. Library updated accordingly.

w00t! :) Thanks for the update.
