Thinking about it, i haven’t had a proper vacation in a while, now that I live in Barcelona, with several ski spots relatively near me, and with a 1-week holiday in April this seems to be the perfect time for me to hit the slopes. Now of course I will be bringing my HERO7 Black. I’ve lost 3 cameras in the past, and apparently ski spots are prime location to lose your camera so my HERO7 Black is ready with my name on a sticker at the top near the lens and the trusty IF_FOUND.txt in the SD card. But I want to be extra sure I don’t lose it and that I can also see how much battery is left and plan accordingly. After some tinkering and buying stuff on Amazon I came up with a simple solution: An ESP32 board that hooks onto the undocumented GoPro bluetooth device API and notifies me when it’s connected and when it’s not.
