Using a CC3000 board, and an Uno clone, I have managed to get other non blynk examples of wifi connectivity to work.
I know that D13 is the internal LED pin,
I have Blynk connected to the board using the following ino code:
#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
// These are the interrupt and control pins for СС3000
#define ADAFRUIT_CC3000_IRQ 3
#define ADAFRUIT_CC3000_VBAT 5
#define ADAFRUIT_CC3000_CS 10
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = "my code";
// Your WiFi credentials
char ssid = "SSID";
char pass = "PASS"; // Set to "" for open networks
Blynk.begin(auth, ssid, pass, WLAN_SEC_WPA2);
// Or specify server using one of those commands:
//Blynk.begin(auth, ssid, pass, "server.org", 8442);
//Blynk.begin(auth, ssid, pass, server_ip, port);
however when I assign a toggle switch to D13 I can not get the LED on D13 to toggle on or off, am I over looking anything?
