Adafruit CC3000 WiFi stuck on "Initializing"

Post by femtoduino »

Hello everyone!

I'm really happy to try out Adafruit's CC3000 WiFi module with a femtoduinoUSB.... but after hooking it all up according to the wiring info... my Serial console only gets to "Initializing CC3000".

Then, nothing.

I've tried reading through other posts, and changing the time out threshold to something higher, but alas, it was for not.

Is there anything else I can do to trouble shoot? Any recommendations?

Thanks!

- Alex

EDIT: Is it possible reflection may be a culprit? Do I perhaps need some kind of series termination as per this arduino thread? http://forum.arduino.cc/index.php?PHPSE ... =164007.90

Post some pictures of your soldering and wiring. You don't seem to be communicating with the CC3000

...Almost uploaded them... until I noticed I had gotten the MOSI and MISO lines backwards. I was too giddy with joy to see things clearly. :-)

Put them in the right order, fixed my obviously erroneous documentation at the femtoduino.com/spex/femtoduino-usb page (and femtoduino page) to correctly label the MOSI and MISO pins, and BAM! Femtoduino + Adafruit CC3000 = Internet!

Here's the result of the GeoLocation example sketch:
