Steps to Compile the program

# run the export script
. /opt/esp-idf/export.sh

# Go to one of the server's code
## go to client
cd client-server/client
## go to server
cd client-server/server

# build the code
idf.py build

# flash the board
sudo idf.py flash

1. Set the ESP32 target (if you haven’t done so already or if you need to specify a particular ESP32 chip variant):

   idf.py set-target esp32

2. Configure the project (optional, required only if you need to change project configurations or if it's the first build):

   idf.py menuconfig

   • Navigate through the menuconfig if you need to customize your build configurations. Save and exit.

3. Clean the project (optional, recommended when switching between client and server builds to avoid conflicts):

   idf.py fullclean

4. Build the project:

   • For the client or server, depending on the environment variable set or the conditional configuration in your CMakeLists.txt, simply run:

     idf.py build

   • This command compiles the project, and if successful, generates the firmware binaries.

5. Flash the firmware to the ESP32 (ensure your device is connected):

   idf.py -p (PORT) flash

   Replace (PORT) with the COM port your ESP32 is connected to (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux/Mac).

6. Monitor the output (optional):

   idf.py -p (PORT) monitor

   This command opens the serial output monitor. Use CTRL+] to exit the monitor.
