Bluetooth screen mirroring – What is the principle of Bluetooth screen mirroring? Steps to use Bluetooth screen mirroring

Bluetooth screen mirroring is a wireless transmission technology based on the Bluetooth protocol. Its principle is to use the Serial Port Protocol (SPP) in Bluetooth technology to pair smart terminals (such as smartphones, tablets, etc.) with display devices (such as televisions, projectors, etc.), and then transmit the image through protocols such as Miracast and AirPlay. During the transmission process, the data will be compressed and encoded to meet the requirements of wireless transmission, and finally decoded and displayed in real-time on the display device.

The steps to use Bluetooth screen mirroring are as follows:

1. Ensure that both mobile devices and large screen devices support Bluetooth functionality and have Bluetooth enabled. The distance between devices should not be too far, usually around 10 meters.
2. Turn on the Bluetooth function on the large screen device, and then click on the search for nearby devices in the Bluetooth menu of the mobile device.
3. After waiting for a period of time, the name of the large screen device will appear in the list of available devices. Click on the device name to pair, and after successful pairing, the mobile device and the large screen device can establish a Bluetooth connection.
4. After successful connection, select the content that needs to be projected on the mobile device to transfer it to the large screen device for display.

It should be noted that the transmission speed and stability of Bluetooth screen casting may be affected by various factors such as device performance, Bluetooth version, and environmental factors. If there are problems such as lag or delay during the screen casting process, you can try adjusting the device position, reducing interference, upgrading the Bluetooth version, and other methods to solve them.
In addition, different devices and operating systems may have slightly different levels of support and operation methods for Bluetooth screen mirroring, so specific device instructions and operation manuals need to be referred to when using it.
