i am using a ttgo t call 800 to control a light from blynk app by a switch/button. when ever power reset is done gprs conection gets established but the digital output of pin gives 0/low irrespective of the switch/buttton state in blynk. after i change the state of button in app then it is getting synced.
for example if the button state is ON/high before power reset after the power comes the digital out put of pin still 0/low . if i change the state from ON to OFF Then ON from app then the digital out put of pin goes 1/high.
so how to get it synced automatically after power reset.
here is the code
