With the advent of the Internet of Things era, wireless transmission is also becoming more and more important, of which wireless module is a typical example; because things want to communicate with each other, they need to rely on wireless communication module to help them realize the sending and receiving of signals, so that all kinds bluetooth lte moduleof Internet of Things terminal devices have the ability to network message transmission.
Wireless modules are involved in remote control, telemetry, wireless remote control system, security and fire prevention system, small wireless network, industrial data collection system, wireless crane weighing, wireless electronic scale, vehicle monitoring, non-stop charging, parking management, wireless tagging, identification, biological signal collection, hydrological and meteorological monitoring, robot control, digital audio transmission, etc. So what are the characteristics of the Bluetooth module among the wireless modules?
One, with anti-interference ability: anti-interference ability is strong, can meet different wireless communication environment.
Third, multi-connectivity: Bluetooth can be connected to a variety of devices at the same time, such as the MS50SFA1 master-slave module, the master mode when you can connect multiple slave modules.
Fourth, penetrability: Bluetooth signals can penetrate most non-metallic objects.
V. Transmission security: Through the customized encryption and decryption algorithm and authentication authentication mechanism to ensure the security of transmission.
Sixth, fast deployment: the establishment of wired communication methods must be set up cable, or digging cable trench, so it requires a lot of manpower and material resources, compared with the use of Bluetooth modules to establish a dedicated wireless data transmission method, saving manpower and material resources, the investment is quite economical.

Does Bluetooth 5.1 pose a risk?
Since Bluetooth is a non-ionizing EMR, it is generally harmless for people and won't harm them. In fact, Bluetooth has low specific absorption rates (SAR), further demonstrating that it is safe for people to use.
Bluetooth spoofing is possible.
A group of university researchers has found a Bluetooth Low Energy (BLE) vulnerability that permits spoofing attacks and may have an impact on how both computers and people do jobs. According to researchers, it could potentially affect billions of Internet of Things (IoT) devices and is still present on Android handsets.
Uses UART Bluetooth?
When a Bluetooth chip is integrated into the system, like in tablet computers, UART is used. When the Bluetooth module is connected as a separate dongle, the USB interface is used.
Does BLE come with Bluetooth 5.1?
