Can you help me with some examples?

Thanks

Hello brice, I'm trying to use an ESP32-WROOM-32D soldered on a PCB (I made it with a standard welder so it's not a great work but it's just for try) with the 2 buttons but it doesn't work. I'm using Arduino IDE and I always get an error "A fatal error occurred: Failed to connect to ESP32: Invalid h...

I did it just yesterday and it worked. I did exactly as you did but I'm using Arduino IDE. I'm using HiLetgo CP2102 TTL/USB.

The test with the DEVKITC works and an external uart/usb it works. I still have problem with the single chip. I have just solder a button between IO0-ground and EN-ground. I'm pressing both of them during the program loading (both are connected to ground so) and then I'm leaving EN first and IO0 lat...
