I’m trying to do a thing where I can connect my GPS to my ESP32 board and use them both at once. I did find a firmware version that can be edited in Arduino IDE, but it’s labeled as buggy, and it is, because I can’t make it compile. However in that code it uses IO9 and 21 for GPS. So I’m trying to find firmware that will have code to use those specific IOs, or something I can easily edit to do the same. Nothing I’ve tried seems to work.
