I'm using the various examples like the WebClient and InternetTime on various networks and the one thing that keeps tripping me up is when the network password is longer than 16 bytes/chars. I have several secure networks that have long passwords that cannot be changed without serious implications.. i.e., hundreds of devices/computers need new passwords entered. Super headache. Some I don't even have the power to change.
The error I get is "Key length must be < 16" when using the cc3000.connectToAP(WLAN_SSID, WLAN_PASS, WLAN_SECURITY); function.
That said I found this place in the code where the MAXLENGTHKEY is defined and it says the following:
#define MAXLENGTHKEY (16) /* Hard coded to 16 in the API! :( */
Link here:

So I decided to see how sad that sad face really was CHANGE the max from 16 to 32, but to my surprise it worked! My 24-byte WPA network password was a success and my connection and WebClient HTTP GET request were up and running.
So I'd submit a pull request to change this, but there seems to be something to it with that frownie face and all... thoughts?

Re: CC3000.connectToAP() and MAXLENGTHKEY
Folks, I too had the same problem but my key is 64 bits long... so making the following two changes to, Adafruit_CC3000.cpp, allowed me to connect to my router with my long key:
Change these two lines:
LINE: 90
LINE: 953
To the following:
LINE: 90
LINE: 953
Maybe you can update the library with this too. I hope it helps anyone else having trouble getting their CC3000 to connect with long keys!
Change these two lines:
LINE: 90
Code: Select all
#define MAXLENGTHKEY (32) /* Cleared for 32 bytes by TI engineering 29/08/13 */
Code: Select all
int8_t _key[MAXLENGTHKEY];
LINE: 90
Code: Select all
#define MAXLENGTHKEY (64)
Code: Select all
int16_t _key[MAXLENGTHKEY];
