I'm completely new to electronics work.
Today I've received the ESP32 board that I ordered. (It's a WROOM-32.) I followed the instructions here. I connected the board to my computer via USB and I successfully installed the CP210x drivers and got a new serial port COM3, but when I tried to connect to the board with that serial port, I got nothing. I'm on Windows 7.
I tried with Tera Term, and it just shows an empty screen.
I tried type COM3
in the shell, but got an empty string.
I tried doing esptool.exe --chip esp32 -p com3 erase_flash
, but I get "Failed to connect to ESP32: Timed out waiting for packet header".
I tried playing with the two buttons on the WROOM32 board, but that didn't help.
Any idea what I'm doing wrong? I'm a complete newbie so it's likely that I'm forgetting something basic.
esptool
is supposed to run without errors when flashing it, right?esptool
internally, cause the error from Arduino IDO is the exact same one I got in my question:Failed to connect to ESP32: Timed out waiting for packet header
