How many Bluetooth devices can be connected to a Huawei phone Bluetooth?

The scope of this question is very large, and the direction is uncertain, and the previous similar question expanded to say not to expand too much? Then it can't be optimized directly. ）

1. A BLE master device can connect multiple BLE slaves, and the current RFCOMM specification specifies that the maximum number of connections is 60.

2. When using BLE in watches and bracelets, you can use them at the same time, and do not exceed the upper limit set by the manufacturer, but at present, Android mobile phones generally do not support BLE very well.

A phone tablet can be paired with 2 or more Bluetooth devices, but only one Bluetooth device can be used at the same time.

For example, a mobile phone is connected to a Bluetooth headset and a Bluetooth **. Bluetooth device in ****, if the mobile phone calls at this time, the device will stop, and the Bluetooth headset will then be connected.

The reason why two Bluetooth headsets cannot be connected at the same time is not that the mobile phone cannot save the Bluetooth addresses of the two earphone devices (the list of saved Bluetooth devices in the mobile phone can be very long), but because of the limitation of Bluetooth transmission bandwidth. Now, in order to ensure the sound quality, the Bluetooth headset has greatly improved the encoding format such as aptx, which makes it possible for Bluetooth to approximate lossless sound quality under the limited transmission bandwidth.

In other words, the previous technology only had enough bandwidth for you to hear a sound. Connecting multiple devices at the same time, if it is not for this kind of streaming, the amount of uplink and downlink data is not large, and most of them are instantaneous - for example, if you come to a text message, the mobile phone only needs to send a command to pass.

Generally, the Bluetooth of the mobile phone is one to two, in principle, it can be paired and connected with two devices, such as connecting a Bluetooth headset, and then connecting a Bluetooth speaker. But only one of the two devices is in working state, and the other is in sleep mode, which can theoretically connect multiple devices with Bluetooth, but it is not so powerful on mobile phones. This generally requires the computer to have a Bluetooth adapter, install Bluetooth software, and search for multiple Bluetooth devices to connect through Bluetooth software.

Mobile phone Bluetooth function convenienceBluetooth connection to the computer to play**, in fact, the computer can also be answered**, usually everyone is used to using the computer to work, you know that when the remote meeting **, you can also answer through the computer, you only need to turn on the Bluetooth function of the mobile phone and the computer at the same time, and complete the connection.

The function of transferring files, there must be many people who often use it, and the Bluetooth function can be turned on on by two mobile phones at the same time, which can be automatically received and matched, without consuming any traffic, to achieve the effect of fast transfer.

Yes, but only if the hardware used by the Bluetooth device is different or does not conflict. Under normal circumstances, if it is not to transfer files, it is recommended that the mobile phone only use one Bluetooth device, and multiple devices are connected at the same time, which may cause the machine to be very slow or not function properly.

One cannot be connected to the nanofiber, which is due to the sound card of the mobile phone and the system will output a Bluetooth audio device from the sound source; In addition, consideration is given to the order of the outputs of multiple audio branches and the power consumption of the device itself. Specifically:

1. It cannot be connected normally, which is due to the sound card and system settings of the mobile phone, and can only output a Bluetooth audio device at the same time, but Bluetooth technology.

It can generally support at least 7 or so devices to be connected;

2. Although there is no big restriction on Bluetooth connection, due to the above considerations of audio cover and output delay, you cannot connect an output device such as a mobile phone with multiple Bluetooth audio devices, but you can connect with multiple different Bluetooth devices such as watches and smart home appliances;

3. In addition, connecting multiple Bluetooth devices for a long time will cause the power consumption of the mobile phone to rise, on the other hand, multiple processes are used at the same time, which seriously affects the speed and performance of the machine, and even various functions interfere with each other and cannot operate normally;

<>nbsp;The mobile phone can be connected to multiple Bluetooth devices at the same time, but the Bluetooth version is required above, if the number of Bluetooth connected at one time is too large, it may lead to a decrease in the efficiency of Bluetooth operation, in addition, the number of Bluetooth connections can be set in the developer options of the mobile phone, which is generally limited to 3.

How to set the number of Bluetooth devices connected to your phone

Take the Huawei P40 (as an example, in the phone system update page, you can set the number of bluetooth devices to 3 in the developer options.

Take the Apple 12 (for example, the Apple phone does not have the option to set the number of Bluetooth connections, but the number of Bluetooth connections should not exceed 3.

1. Taking Bluetooth headset as an example, the mobile phone cannot be connected to multiple Bluetooth devices at the same time, which is due to the reason of the mobile phone sound card and system settings, and can only output a Bluetooth audio device at the same time. In addition, consideration is given to the order of multiple audio outputs and the power consumption of the device itself, as well as operational efficiency.

2. Bluetooth headset is a hands-free headset that applies Bluetooth technology, which allows users to avoid the stumbling of wires and use headphones easily in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency, it has mono, stereo, true wireless three types, including HSP, HFP, A2DP three specifications.

3. Bluetooth technology is not only used in computers, but also in many electronic devices such as mobile phones, digital cameras, video cameras, printers, fax machines, home appliances, etc., to achieve wireless communication without having to drag a tail (connecting line). With the popularization of Bluetooth technology, home decoration is no longer troubled by the wiring of electrical appliances; When using home appliances, you don't have to worry about a lot of remote controls, a mobile phone or a car key can do everything; When you are away from home, the company's work arrangement and the picture of your relatives at home can be obtained anytime and anywhere; There is no need to queue up for punching in and paying fees, passing near the payment point, and you can easily complete the wide application of Bluetooth technology without entering the door, which will make our lives extremely easy.
