Hello friend, I'm from Brazil. Did you use the standard bluetooth library? because the esp32-s3 uses low energy bluetooth, i'm having trouble getting the library to work. Is the software compatible with ELMDuino? with all the commands? could you inform? I have the same display board, but the display I'm using is 7 inches.
