How to get wifi working?
I am using a Adafruit CC3000 shield with NucleoF401, using the CC3000 code example compiles fine but my board doesn't seem to connect. I have a 16x2 LCD which works fine before reaching any wifi commands but won't work after. I am sure that the wiring is fine and I have called the class correctly. Here is my simplest code example:
int main() { init(); board dependent init pc.baud(115200); lcd.locate(0,0); lcd.printf("cc3000"); wifi.init(); int con = wifi.connect(); if(con == -1) { lcd.locate(0, 0); lcd.printf("Failed"); } else { lcd.locate(0, 0); lcd.printf("cc3000:connected"); lcd.locate(0, 1); lcd.printf("IP: %s",wifi.getIPAddress()); } }
Any help would be much appreciated.
Not certain if you asked this question already. how do you feed the cc3000? What's your connection? The cc3000 requires quite a current which is usually not sufficient to draw from only usb..
