Hey guys,
So I'm trying to follow this video tutorial and I'm running into this error. I have both the ESP-12S (the one used in the video) and the ESP-32. I'm new to the Arduino world so maybe one works better than the other for my problem? Anyways, by doing some research, there might be some firmware that I have to flash onto the chip (tried following a tutorial for that and that didn't work either of course) so I'm out of ideas. If anyone can point me into the right direction that would be awesome. Thanks
Here's the video:
Here's the error:
