How to block a bluetooth signal?
I've heard that the security of smart devices is getting worse recently. Many hackers can use WIFI and bluetooth signals to break into smart devices and steal personal data and bank accounts. So, I want to know how to block the bluetooth signal to make sure my smart device is safe.
Indeed, many public places now have fake WIFI and bluetooth enabled by hackers. If you don't pay attention, you may be hacked into smart devices.
In response, the China institute of network security has developed a device called a WIFI signal jammer. The device is designed for hacking wi-fi and bluetooth signals. It can effectively block the surrounding WIFI and bluetooth signals, preventing you from accidentally connecting to the fake WIFI.
