Environment Setup
source ~/esp/esp-idf/export.sh # Activate ESP-IDF (every shell)
Build & Flash
cd ~/git/esp32-hacking/get-started/csi_recv_router
idf.py set-target esp32 # Set chip target
idf.py menuconfig # Configure WiFi/UDP settings
idf.py build # Compile firmware
idf.py -p /dev/ttyUSB0 flash # Flash to device
idf.py -p /dev/ttyUSB0 monitor # Serial monitor (Ctrl+] to exit)
idf.py -p /dev/ttyUSB0 flash monitor # Flash + monitor combined
idf.py fullclean # Clean build directory
idf.py reconfigure # Re-fetch managed components
# IDF v6.1 workaround (after clean/reconfigure)
