General Steps for Reliable Connection

1. Upload Code:
Temporarily disconnect the HC-05 module's TX and RX pins from the Arduino.
Upload the code via the Arduino IDE.

2. Reconnect HC-05:
After uploading, connect the HC-05 TX and RX pins to the Arduino RX (0) and TX (1) pins, respectively.

3. Test Communication:
Pair the HC-05 module with your Bluetooth device (phone, tablet, etc.) and test the communication as per your code logic.
