Thats a good start, it confirms that it can connect to wifi successfully.
Now clean up the code and get rid of the webserver garbage - give me a few mins
So, ArduinoWiFi.h gives us the following:
void connect(char* , char*);
Limited further information but it suggests that WiFi.connect may allow for an SSID and PSK.
Let me write a test quick.
Update: Nope, not winning with any of the combinations of wifi / blynk options, without an actual board to test on I'm hesitant to mess with the libraries.
If i manage to source one locally I'll try help out more.
