If my Real Time Clock on Arduino loses its time, is there a way to “sync” it using Blynk to the actual time on my android phone or iphone. Just looking for outline of method, not any code for now.
Hello. Did you see this https://github.com/blynkkk/blynk-library/blob/master/examples/Widgets/RTC/RTC.ino ?
Thanks. This seems to be the right thing. I’ve never used Blynk, have done a little arduino, so many questions. What is the link between app and arduino? Looks like ethernet (wifi?) from the code. Can it be bluetooth or direct USB connect? I would like to do it without having to know any passwords, just need Blynk app on phone (any phone).
At the moment we support ethernet, wi-fi. USB. BT will be next.
Account is needed for synchronization among devices. You may control hardware from any phone if you have account.
