I am controlling various modules esp8266 with the same Auth Token. I usandos virtual pins to control each module. Example: pin 01 for virtual module 01 and so on. Everything is going well in my project. I am using the WiFiManager.h library to set up wifi in each module. I also want to enjoy adiconar in each module esp82266 the virtual pin to which it will respond. So I escoher any module and configure with the virtual port that I want. The problem is that I tried to put a variable in BLYNK_WRITE (variable), but it does not accept or int or String. So I can not take IDENTIFICATION virtual pin recorded in eeprom. Can someone help me?
You should use global variable.
