I wished it were more straightforward, but alas the interlinking of different tech and platforms is always challenging. I spent several hours trying to figure out how to consistently connect my GoPro Hero 9 to my phone's hotspot.
Basically, my goal was to use my phone as a connection for my GoPro so I could livestream on Twitch (https://www.twitch.tv/electricbikeadventures) while riding!
I know there are great solutions out there but all cost upwards of $1000 when all is said and done. Eventually I'll get there I'm sure. It's a slow burn kind of thing.
But for now, I'm trying to get by on cell phone and GoPro.
I wound up creating a quick video on it, if you're interested to solve similar issues I had. Check out the description in the video below for a step by step, or of course watch the video itself.
