The best method to prevent Bluetooth from being exploited is to always disable Bluetooth when it is not in use. Keeping Bluetooth turned off when it’s not needed helps prevent attackers from exploiting vulnerabilities in the protocol, such as unauthorized access, data theft, or remote control of the device. This reduces the attack surface and minimizes risks like Bluejacking, Bluesnarfing, or Bluebugging. Additional important security practices include:

• Use the most recent Bluetooth version and enable Bluetooth Low Energy (BLE) link-layer encryption to protect the confidentiality and integrity of transmitted data.
• Avoid using "Just Works" pairing when possible as it lacks authentication.
• Only accept Bluetooth connections from known and trusted devices.
• Keep device firmware and software up to date to patch vulnerabilities.
• Consider using application-level encryption for highly sensitive data exchanged over Bluetooth.
• Reject connection requests from unknown devices.
• Disable discoverable mode when not actively pairing.

Following these steps contributes to strengthening Bluetooth security and preventing exploitation effectively.
