What is the difference between Bluetooth 5 0 and 5 2

Bluetooth provides an upgraded version of the original Attribute Protocol (ATT), called Enhanced Attribute Protocol (EATT), which is more efficient and secure than ATT. And Bluetooth offers a Synchronous Channel (ISOC) – a completely new feature that supports both connection-oriented and connection-less communication. With these advancements and efficiency gains, Bluetooth offers faster pairing capabilities as well as longer battery life.

Bluetooth and the differences are: different transmission speeds, different working distances, and advertisedPacketsDifferent.

1. The transmission speed is different

Compared with the Bluetooth version, Bluetooth can bring twice the data transmission speed, and the data transmission capacity can be increased by 800%. In other words, those who use Bluetooth can transmit and receive more data at a faster speed.

Second, the working distance is different:

Compared with the Bluetooth version, the bandwidth (transmission speed) has been increased from 1Mbps to 2Mbps, and the transmission distance has been increased to 4 times, that is, the theoretical effective working distance is 300 meters, and the low-power mode is also acceptable.

3. The advertised packets are different:

Compared with the Bluetooth version, Bluetooth can advertise 255 bytes of data packets instead of 31 bytes, thus reducing the loss of transmission efficiency caused by frequency band interference.

The main problems with Bluetooth are as follows:

1. The power consumption of Bluetooth. Bluetooth does not transmit data frequently and consumes less energy in the process of transmitting data, but in order to respond to connection requests in a timely manner, polling for access while waiting is very energy-intensive.

2. The connection process of Bluetooth is cumbersome. The connection process of Bluetooth involves multiple information transmission and verification processes, which on the surface does not seem to make users feel the complex connection process, but the repeated data encryption and decryption process and the authentication process that needs to be carried out for each connection are a great waste of device computing resources.

3. The security of Bluetooth. The first pairing of Bluetooth requires the user to pass a PIN code.

For verification, the PIN code is generally composed of only numbers, and the number of digits is very small, generally 4 6 digits. After the PIN code is generated, the device will automatically use Bluetooth's built-in E2 or E3 encryption algorithm to encrypt the PIN code, and then transmit it for identity authentication.

In this process, hackers are likely to crack the PIN code by intercepting the packets, disguising themselves as the target Bluetooth device to connect, or using a "brute force attack".

The differences are as follows: 1. Different data transmission speeds: Compared with the Bluetooth version, Bluetooth can bring twice the data transmission speed, and the data transmission capacity is increased by 800%.

In other words, Bluetooth can be used to transmit and receive more data at a faster speed. 2. Different working distances Compared with the Bluetooth version, the bandwidth (transmission speed) has been increased from 1Mbps to 2Mbps, and the transmission distance has increased to 4 times stronger, that is, the theoretical effective working distance is 300 meters, and the low-power mode is also acceptable. 3. Different data packets advertised Compared with the Bluetooth version, Bluetooth can advertise 255byte of data packets, instead of 31bytes, thereby reducing the loss of transmission efficiency caused by frequency band interference.

The difference between Bluetooth and and.

Dear, <>

Hello, glad to answer for you. The differences between Bluetooth and and are as follows: 1. Bluetooth began to add indoor positioning assistance functions, combined with Wi-Fi to achieve indoor positioning with an accuracy of less than 1 meter, the upper limit of the transmission speed in low-power mode is 2Mbps, and the effective working distance can reach 300 meters; 2. The Bluetooth function adds direction finding function and centimeter-level positioning service on the basis of Bluetooth, so that the indoor positioning will be more accurate; 3. Bluetooth is based on the Bluetooth to add enhanced ATT protocol, LE power consumption control and signal synchronization functions, so that the connection is faster, more stable, and better anti-interference.

1. Different data packets advertised: Compared with the Bluetooth version, Bluetooth can advertise 255byte of data packets, instead of 31bytes, thereby reducing the loss of transmission efficiency caused by frequency band interference.

2. According to the different transmission speeds: compared with the Bluetooth version, Bluetooth can bring twice the data transmission speed, and the data transmission capacity is increased by 800%. In other words, those who use Bluetooth can transmit and receive more data at a faster speed.

3. Different working distance: Compared with the Bluetooth version, the bandwidth (transmission speed) of Bluetooth has been increased from 1Mbps to 2Mbps, and the transmission distance has increased to 4 times stronger, that is, the theoretical effective working distance is 300 meters, and the low-power mode is also acceptable.

Bluetooth main features.

1. In order to meet the needs of mobile clients, its power consumption is lower and compatible with older versions.

2. The upper limit of the transmission speed in low-power mode is 2Mbps, which is twice that of the previous version.

3. Add navigation function, which can achieve indoor positioning of 1 meter.

4. The effective working distance can reach 300 meters, which is 4 times that of the previous version.

5. Bluetooth has a wider coverage range and a four-fold speed increase for low-power devices.

The difference between Bluetooth and Bluetooth is that Bluetooth transmission is more stable, saves power, and is compatible with Bluetooth.

Some people copy the answer is very misleading, Bluetooth bandwidth is already 24mbps... The 2M bandwidth mentioned here is low power consumption... And it refers to Bluetooth as opposed to Bluetooth.

This kind of random answering will teach a lot of people!!

The biggest difference from Bluetooth to Bluetooth upgrade is not in the audio quality and distance transmitted, but in the addition of a function that can achieve centimeter-level positioning without wifi assistance.

In terms of the basic function of Bluetooth headsets, there is no substantial change.

You just buy a Bluetooth headset to listen to songs, and there is no difference between the choice and the song.

Compared with Bluetooth, the latest version of Bluetooth has added a direction finding function and centimeter-level positioning services, which makes indoor positioning more accurate, and can also accurately locate small objects to avoid loss of items. The transmission rate and distance are consistent.

The protocol is different, that is, the larger the number, the more complete the Bluetooth protocol, and then the previous numbers are supported, not necessarily the back, but the later numbers are all supported in the front.

Hello, it's just that some functions have been optimized, and the teleportation ability is stronger!

The difference between Bluetooth and and, and the difference between and refers to a large grid.

This is definitely the faster transmission speed, and then the Bluetooth connection is farther away.

There must be a difference, his system is different, okay.

The difference between Bluetooth and and.

Bluetooth1 and both belong to the latest version of Bluetooth technology, and the main differences between them are as follows:1

Speed and distance: Bluetooth has a maximum transmission speed of 2mbps, and the distance is about 200 meters; Bluetooth has a maximum transmission speed of 2mbps and a distance of about 300 meters; Bluetooth has a maximum transmission speed of 2mbps and a distance of about 400 meters. 2.

Low Energy: Bluetooth1 and both support BLE technology, which can achieve low-power connection and broadcasting.

3.Audio transmission: Bluetooth and Syngene support LC3 codec, which can achieve higher quality audio transmission, while Bluetooth adds LE-AUDIO function, which can support multi-channel audio transmission and higher quality audio codec.

4.Indoor positioning: Bluetooth and both have added a directivity function, which can achieve more accurate indoor positioning by measuring the direction of the signal first dispersion.

In general, compared with the and, in addition to the speed and distance improvement, Bluetooth also adds the LE-AUDIO function and directivity function, and further strengthens the security.
