1, Huawei Beam with sharing function
Because you need to turn on NFC before using Huawei Beam, many people mistakenly think that it uses NFC to transfer files.
In fact, NFC is only used to establish a connection between two mobile phones, which means to say hello before transmitting data, "Hello, I want to send you a file!" " After the two mobile phones "shake hands", they will turn on Bluetooth before transmitting data, and then use Bluetooth to transmit data.
We know that NFC needs to be close to transmit data, but in the process of file transmission, we separate the two mobile phones and the transmission will not be interrupted, which can also prove that Huawei Beam does not use NFC to transmit data.
▼ When two mobile phones contact, Bluetooth will be automatically turned on to transmit data.
It is convenient for Huawei Beam to transmit small files, because only NFC and Bluetooth will be used, so it will not affect the current WIFI connection.
2. Huawei shares functions.
When using Huawei Beam, Bluetooth is not suitable for transmitting large files because of its limited data transmission speed. You can use Huawei Share at this time.
When you open Huawei Share, you will see that it will automatically turn on Bluetooth and WLAN, that is to say, it uses Bluetooth to search and discover devices, and uses WLAN to directly transmit data, which is one grade higher than Huawei Beam, and the actual use speed is different, mostly between 20-50m/s.
In addition to Huawei's own sharing tools, some software also supports end-to-end file transfer, such as QQ face-to-face fast transfer, and the principle is similar to Huawei Share.
Some people may ask, now everyone uses tools such as WeChat to send documents. What is the use of Huawei Share and Huawei Beam?
The biggest feature of Huawei Share and Huawei Beam is that they don't need to connect to the network. Both of them transmit data through end-to-end direct connection, which is very useful when there is no signal or you don't want to transmit files with traffic.
In addition to files, our installed applications can also be transmitted through ring dimension sharing or Beam, which is also very practical in some cases. For example, some apps are only available in Google Play Store, and it is well known that downloading Google Play apps in China is very troublesome. If you install these applications, your friends will want to install them after reading them. At this time, you can press the application on the desktop and share it with him through the ring dimension or Beam, which saves a lot of trouble.
3. Remote control
First of all, remote operation here refers to operating the mobile phone through Bluetooth, not remote control through the network.
What's the use? Just think about winter when your hands don't want to stick out of bed.
Or the following situation where only your fingers can move.
In most cases, we want to operate the mobile phone remotely by installing the corresponding APP, but this is not the function we want to describe this time. Using one mobile phone to operate another mobile phone, we still have to operate the mobile phone by hand.
What I want to say here is to use a Bluetooth controller to operate the mobile phone.
You just need it.
Or it
Or is it?
Turn on this function, so you don't have to put your hand out of bed when you watch movies in winter. In fact, this feature phone comes with it. It's just hidden deep enough that many people don't know it.
Open settings-> "intelligent assistant"->; "accessibility"->; "Switch control"
After turning on the switch control, we can operate the mobile phone through connected Bluetooth devices, such as camera Bluetooth controller and Bluetooth remote controller.
If it is a device with fewer buttons, such as a camera Bluetooth controller, it is very troublesome and slow to operate, and it is of little practical value. Mainly through "automatic scanning" to achieve the movement and selection of pressed keys.
There are two ways to move, which can be realized by turning on or off "point scanning"
Turn on automatic scanning, and turn off "point scanning". In the opened interface, the cursor will constantly switch between various operable places. When switching to the location you want to click, you can click on the location by pressing the button of the remote control. It's a bit like pressing Tab to move on a computer, and then pressing Enter to confirm.
▼ Turn off the movement mode after "point scanning"
When "Point Scan" is turned on, the position you want to click is confirmed by two horizontal lines and vertical lines. When you press the button for the first time, the horizontal line will stop moving, and then the vertical line will start moving. When you press the button again, the intersection of the two lines is the click position.
If there are two more buttons on the remote control, you can turn off "Auto Scan", which is more convenient to move manually.
Both of the above operations can only be used to replace the "finger move and click" operation. What if other operations are needed, such as long press and sliding?
