config ESPTOOLPY_COMPRESSED
	bool "Use compressed upload"
	default "y"
	help
		The flasher tool can send data compressed using zlib, letting the ROM on the ESP chip
		decompress it on the fly before flashing it. For most payloads, this should result in a
		speed increase.

choice ESPTOOLPY_BEFORE
    prompt "Before flashing"
    default ESPTOOLPY_BEFORE_RESET
    help
        Configure whether esptool.py should reset the ESP32 before flashing.

        Automatic resetting depends on the RTS & DTR signals being
        wired from the serial port to the ESP32. Most USB development
        boards do this internally.

        The "Reset with ESP32R0 Windows workaround" option works
        around an automatic reset bug in hardware, when using Windows
        with some development boards. This fix only works if you're
        using a silicon revision 0 ESP32.

        Automatic resetting depends on the RTS & DTR signals being
        wired from the serial port to the ESP32. Most USB development
        boards do this internally.
