I've heard that smart device security is getting worse recently. Many hackers can use WIFI and Bluetooth signals to break into smart devices and steal personal data and bank accounts. Therefore, I want to know how to block the bluetooth signal to keep my smart device safe.

Many public places now have fake WIFI and Bluetooth activated by hackers. If you are not careful, you can be hacked on smart devices. To this end, the China Network Security Research Institute has developed a device called wifi jammer. The device is designed to crack Wi-Fi and Bluetooth signals. It can effectively block surrounding WIFI and Bluetooth signals, preventing you from accidentally connecting to fake WIFI.
