Would it be possible to add Bluetooth or Wi-Fi control of an external GoPro to start/stop video recording with a raspberry pi as the companion computer?
I was thinking to use a GoPro remote and control the buttons with a relay channel but I thought it might be cleaner to do it with the onboard Bluetooth.
There’s some discussion here about underwater wifi - the range is apparently about 5-10cm, and you likely need an acrylic enclosure. At a guess I imagine Bluetooth would be similar given it’s a very similar frequency band, but I’m also unsure whether it has the same kind of broadcast strength (so it may not be as effective).
From what I recall there are also a few different posts on wired connections to control GoPros. This one might be relevant, and it may also be worth searching the forum for some others
Thank you so much! I’ll take a look at those posts.
