Hello all !
for my first project, i have write a Dog Feeder, and i’ve write a function for reversing motor when the current is overload (in some case, the Wheel is blocking, to avoid this -> change rotation 
but !
it work with a simple process into void section, and not working into BLYNK_WRITE section 
When i press V0 virtual button, it launch doFeed function, and into this function , testCourantMoteur check the current of motor and it change (or not) a flag.
into the serial monitor, i can’t the value of current, as if doesn’t launch the checkCurrentFunction !
I’ll rip my hair out!
i have extract some code from my project, if you have an idea, i take !
ps : if you think i must post all code, tell me.
