• Failed to flash firmware:
  • Check serial connections (TXD0, RXD0, GND) to your USB-to-UART converter.
  • Ensure the module is in bootloader mode (typically by holding down a BOOT button while resetting, or specific pin configurations).
  • Verify correct COM port selection and baud rate in your flashing tool.
  • Ensure your power supply is sufficient, as flashing can draw more current.
• Problemes de connectivitat Wi-Fi/Bluetooth:
  • Check antenna connection (if external) or ensure the on-board antenna is not obstructed.
  • Verify Wi-Fi credentials (SSID, password) and Bluetooth pairing procedures in your code.
  • Ensure sufficient power supply, as wireless communication can cause voltage drops if the supply is weak.
  • Check for interference from other 2.4 GHz devices.
• Module resets unexpectedly:
  • This often indicates power supply instability. Ensure your 3.3V supply can provide enough current, especially during peak loads (e.g., Wi-Fi transmission). Add decoupling capacitors near the module's power pins.
  • Check for watchdog timer resets in your firmware.
