CC3000 - invalid serial printout

Post by roboscare »

Hello,
After having played a lot with my Arduino, I tried to run an Adafruit CC3000 WiFi Breakout in connection with Arduino UNO.
I built up all connections according to your lesson on
https://learn.adafruit.com/adafruit-cc3 ... 0-breakout
Then I installed the appropriete library on my computer which worked fine.
Finally I tried one of your example-sketches, e. g. "buildtest.
Compiling and upload went without errors.
But then only problems arose:
I didn't not only get no WLAN-connection but I got not even one readable print with the serial.print command on the serial monitor.
The monitor opened only delayed - after 4-5 opening commands.
Only a few unreadable letters were transmitted. On the CC3000 a green led-light is on - so hardware seems to be ok.
Earlier I had no problems with this monitor, so I think there is no hardware defect on the board.
What should I do next?
Thanks for help

Oh sorry, I disvovered that the bautrate in this sketch has to be adapted to 115200 - so now the problems with the seriel monitor are clearified.
But the program comes not further than to "Initializing..." in the routine cc3000().begin. that's not much!
has anyone a suggestion - ?

Could you post a picture of the breakout and how you have it connected to the UNO?

Hello,
thanks for your interest!
the connection is as follows:
IRQ - pin 3; VBEN - pin 5; CS - pin 10; MOSI -11; MISO - 12; SCK - 13; Vin - 5V; GND - GND

you see the green light glowing - so I guess the hardware is alive!?
