***Install esp-idf***
git clone --recursive https://github.com/espressif/esp-idf.git

cd esp-idf

./install.sh esp32s3

. ./export.sh

***Set target***
Go to the solution folder:
idf.py set-target esp32s3

***Detect PORT***
The device which doesn't appear in the second run is the one we want:
ls /dev/tty*
unplug it:
ls /dev/tty*

Now we need permission to access the device:
sudo -S chown -R guest:users /dev/ttyUSB0

***Build***
idf.py -p /dev/ttyUSB0 flash monitor

***Configure Rust Environment***
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

***Build espup (https://github.com/esp-rs/rust-build)***
Linux x86_64:
	curl -L https://github.com/esp-rs/espup/releases/latest/download/espup-x86_64-unknown-linux-gnu -o espup
MacOS x86_64:
	curl -L https://github.com/esp-rs/espup/releases/latest/download/espup-x86_64-apple-darwin -o espup
MacOS aarch64:
	curl -L https://github.com/esp-rs/espup/releases/latest/download/espup-aarch64-apple-darwin -o espup

chmod a+x espup
./espup install
. ~/export-esp.sh

***Set default rust for esp***
rustup default esp

***Install ldproxy***
cargo install ldproxy

***Clone project (original: https://github.com/ivmarkov/rust-esp32-std-demo)***
git clone https://github.com/fulalas/rust-esp32-std-demo

cd rust-esp32-std-demo

***Export wifi credentials variables***
export RUST_ESP32_STD_DEMO_WIFI_SSID=<ssid>
#export RUST_ESP32_STD_DEMO_WIFI_SSID=Trustpower_2.4GHz_0117

export RUST_ESP32_STD_DEMO_WIFI_PASS=<password>
#export RUST_ESP32_STD_DEMO_WIFI_PASS=qocuditafa

[Install Python pip]

***Build for ESP32-S3 -- the flag '--features esp32s3_usb_otg' is to enable the LCD***
cargo build --release --target xtensa-esp32s3-espidf --features esp32s3_usb_otg

In case of this error:
	error[E0609]: no field `tm_gmtoff` on type `tm`
	   --> ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/time-0.1.45/src/sys.rs:394:30
			|
		394 |             let gmtoff = out.tm_gmtoff;
			|                              ^^^^^^^^^ unknown field

Solution is changing the offending line to:
let gmtoff = out.tm_hour;

***Install espflash***
cargo install espflash

***Detect PORT***
The device which doesn't appear in the second run is the one we want:
ls /dev/tty*
unplug it:
ls /dev/tty*

Now we need permission to access the device (considering it's ttyUSB0):
sudo -S chown -R guest:users /dev/ttyUSB0

***Flash application into ESP32-S3***
#espflash /dev/ttyUSB0 target/xtensa-esp32s3-espidf/release/rust-esp32-std-demo
espflash flash target/xtensa-esp32s3-espidf/release/rust-esp32-std-demo

The device will reboot and run the application. After a while it should connect to the wifi network and display its IP address that will be the endpoint.

***Get the application output in the developer machine***
espflash serial-monitor

It will probably print something like this:
	Detected 2 serial ports. Ports which match a known common dev board are highlighted.

	  /dev/ttyACM0 - USB_JTAG_serial_debug_unit
	❯ /dev/ttyUSB0 - CP2102N_USB_to_UART_Bridge_Controller

Select with the keyboard arrow key the device used to flash the application -- in my case /dev/ttyUSB0 -- then press Enter.

If you want to change the code, you need to build and flash.
