Title: Use Longines App to set up exact TIME by use LED on handy
Post by: JaraKava on Mar 21, 2019, 12:27 pm
Longines uses an LED flashlight on the mobile to set the exact time on the watch. (see" Its free application is intended for this purpose. When pressed the button on handy, the LED sends a light message to the watch. But this could also be used to set the time in Arduino applications. I attach a picture of what it looks like.
It's a simple sequence. Since it is also known what is in the message (time) it will be easy to decode it.
Can anyone do that?
