The Bluetooth Voice-control Relay example is primarily designed for learning and demonstrating Bluetooth communication and relay control functions.
The JDY-31 Bluetooth module comes with a default pairing password (usually 1234), and you can also change the password using AT commands. For example, sending AT+PIN5678 will set the new password to 5678.
For general learning, experimentation, and DIY projects, this level of security is usually sufficient. However, we do not recommend using this example directly in real‑world applications that require high security without adding additional authentication or protection mechanisms.
This kit is mainly intended for learning, prototyping, and experimental purposes.
If you have any further questions, please feel free to ask.
