Flashing BlueBuzz.ino.bin to ESP32 using esptool (Windows & macOS)

After building your firmware (BlueBuzz.ino.bin), you can upload it to your ESP32 board using esptool.

1. Download esptool

• Windows:
  Download the latest esptool.exe release and extract it.

• macOS:
  Install via Homebrew:

  brew install esptool
  

2. Connect your ESP32

• Plug your ESP32 board into your computer via USB.
• Identify the serial port:
  • Windows: Check Device Manager (e.g., COM3)
  • macOS: Use ls /dev/tty.* (e.g., /dev/tty.usbserial-xxxx)

3. Put ESP32 into Bootloader Mode (if needed)

• Hold the BOOT button while pressing EN (reset), then release EN first.

4. Flash the firmware

Windows (Command Prompt):

esptool.exe --chip esp32 --port COMx --baud 921600 write_flash -z 0x10000 BlueBuzz.ino.bin

• Replace COMx with your actual COM port (e.g., COM3).

macOS (Terminal):

esptool.py --chip esp32 --port /dev/tty.usbserial-xxxx --baud 921600 write_flash -z 0x10000 BlueBuzz.ino.bin

• Replace /dev/tty.usbserial-xxxx with your actual device.

---

Note:

• Make sure the serial port is not in use by another program (like Arduino IDE).
• If you get a permissions error on macOS, try:

  sudo chmod 777 /dev/tty.usbserial-xxxx
