也不知道是不是這樣。sdk (framework, library) 跟 toolchain:
結果 build toolchain 就 failed:
Connecting to isl.gforge.inria.fr (isl.gforge.inria.fr)|128.93.193.15|:80... failed: Connection timed out.
S3 的要看：
run 這個，依照你要用的 chip 版本 (以 S3 為例):
./install.sh esp32s3
就會 download 對應的 toolchain (不用自己 build)
一樣，要 access 到 install 的 toolchain，要先
All done! You can now run:
. ./export.sh
這個 env script 會出現：

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:
idf.py build
依照這個getting start guide. copy hello-world, 要 build 的話...
都是用 idf.py 這個 tool.
idf.py set-target esp32s3
idf.py menuconfig
這個 menuconfig 包含很多東西，例如 bt, wifi, rtos, network-stack...etc
之後，用
idf.py build
build 完就會告訴你燒錄的command.
esp32-s3 的話，要 v4.4 以上才有 support,
ref:
使用 v4.3 的化，idf.py -p /dev/ttyUSB1 flash 會出現 Error:
A fatal error occurred: This chip is ESP32-S3(beta3) not ESP32. Wrong --chip argument?
改用 latest (master) 後，就 OK 了：

devkti 上有兩個 microusb port，flash command 的 option，接 UART 時，是 /dev/ttyUSB0，接 USB 時，是 /dev/ttyACM0
燒錄好 hello-world 後，用
picocom -b 115200 /dev/ttyUSB0(ACM0) 就可以看到 hello world console output
燒錄的時候，只要下command 就好，竟然不用按reset...
但是說明有說。如果沒有bootloader，就要手動進入 download mode :
接 UART，按著 BOOT 然後 reset. 如果用 picocom 來看，就會看到：

wifi-ble 測試可以用 blufi，包含android apk 和 esp32 sample code.
是利用手機經由 ble 連線後，設定 wifi ssid/password 的example
Android apk 可以用 AndroidStudio build OK
esp32 sample 一樣，用
idf.py set-target esp32s3
idf.py build
idf.py -p /dev/ttyACM0 flash
要build matter app 的話，先參考：
依照他說的，除了上面的 idf 要裝，還要裝
chip environment
猜的，一樣在 ~/esp/ 下：
git clone --recurse-submodules git@github.com:project-chip/connectedhomeip.git
