"Basically, Bluetooth is backwards compatible, but with Bluetooth Low Energy there is an important exception," Eikenberg says. "Bluetooth 5.0 is slowly becoming established on smartphones. "The benefits of Bluetooth 5 are less focused on smartphones or headphones and more on the Internet of Things." Those include smart home devices such as networked thermostats or robot vacuum cleaners.However, even Bluetooth 5.0 can't match WiFi when it comes to bandwidth. "As a result, large files such as high-resolution photos or videos take longer to transfer via Bluetooth," Knott says.In terms of data security, Bluetooth is generally safe because the connection between two devices is encrypted.
