What to do if in Arduino IDE boards manager, installation is stuck at "Downloading tools (3/3). Downloaded 38,190kb of 125,719kb." when installing ESP32 on Arduino IDE? I have not connected the ESP32 board to my computer, so should I restart the installation after connecting the board, or can I connect it midway installation?

    you can connect the ESP32 at any time you like - it's not going to help or hurt the install of the Espressif framework – Jaromanda X Dec 29 '18 at 7:03
