I would like to know how to make my code work with the new blynk. Its a WOL that worked with the old Mobile Blynk app, but with the new one my protect just disappeared.
I have this set up as datastreams
this is the code, I find wright it but it worked, the “-” that I used are just to fill in the spaces with my personal info I don’t want to show,. It worked perfectly, but just today the old blynk mobila app just shut down and it stoped working.
