Why can't mobile phones always send files to computers via Bluetooth?

Sending files to a computer via Bluetooth is a very old activity, because there are many other ways to choose from now. Whether sending files through QQ, or connecting files through data lines or wireless devices between mobile phones and computers, you can achieve the effect of fast file transmission. Bluetooth is affected by its own signal transmission mode and its transmission speed is limited.

Bluetooth can never transfer files. First of all, we must ensure that the Bluetooth connection between the mobile phone and the computer works normally, that is, sending files from the computer to the mobile phone. If the mobile phone can receive the file sent by the computer, it proves that there is something wrong with the signal of the mobile phone or the computer itself. There's basically nothing to check about the Bluetooth of the mobile phone, because it's all set up, so you can only look at the Bluetooth configuration of the computer and search. Bluetooth is in the control panel, and then change the Bluetooth settings, that is, select com port as the English name of Bluetooth, and then click Add to add the device again and reset the port. Bluetooth can basically work at this time.

Choosing Bluetooth to spread files is really not a good choice. Whether it is the high-speed transmission through the data line or the wireless connection between the mobile phone and the computer, it is much faster than using Bluetooth, because Bluetooth is affected by its own signal propagation, and its propagation speed is very limited, basically it can only be stabilized at about one or two megabytes. If connected by wired data cable, this speed may exceed 10 times, and the corresponding social software,

No, now Bluetooth is not an important channel for spreading files, but a channel for connecting signals. This connection signal may be a Bluetooth keyboard, a Bluetooth mouse, a Bluetooth headset, etc. Because it only transmits a signal change, it doesn't have so much information, so the propagation speed of Bluetooth can fully meet the needs of these devices, but it is very difficult to transmit files because it is too slow.
