@salmanfaris I uploaded prg "standalone ssl"but nodemcu blue ligth blinking after it .no ligth and it not connecting to my phone
Hi @shankar ,
First, try the NodeMCU as standalone and make sure that it's working fine without any problem. then try basic blynk programme with NodeMCU to understand the blynk Virtual Switch and Pin properties.
also please attach the code, so we can check the syntactical issues.
