Changing the sketch:
You have to do two changes as far as I know:
1- The first one is in the declaration field of the cpp file:
char auth[] = "ukvdPk5XW*******************2nXrIdNK6ef";
char ssidblynk[] = "AP no internet connection";
char passblynk[] = "";
2- The second one in Void setup():
//Blynk.begin(auth, ssidblynk, passblynk);
Blynk.begin(auth, ssidblynk, passblynk, "192.168.43.108",8080);
Ps: Change “192.168.43.108” to your IPv4 address.
