What does it mean to adopt Bluetooth standards V1 2 and 2 0?

The transmission speed and effective distance are different.

For us players, it's just a matter of looking at the most critical part, which is summarized as follows:

Compared with the version, the Bluetooth version mainly includes the following four new features.

Frequency Hopping (AFH): The so-called adaptive frequency hopping technology is mainly used to reduce the interference problems between Bluetooth products and other wireless communication devices.

Synchronous Connection-Oriented Links (ESCO): Extended Connection-Oriented Links (ESCO) technology to provide high-level QoS audio transmission, which can further meet the needs of higher-end voice and audio products.

connection: a quick connection. The inclusion of First FHS and Interlaced Scan technology shortens the time of re-search and reconnection, makes the connection process more stable and faster, and makes the use of Bluetooth products smoother.

4.Compatible with Bluetooth version products: Make sure they are backwards compatible with versions of products.

Features of Bluetooth:

In the respecification, EDR appears as a supplement, so what we usually see is:"Bluetooth Core Specification Version + EDR"said.

Its main features are as follows:

Data transfer speeds can be up to 3 times the current rate (and in some cases up to 10 times).

Reduce energy consumption by reducing the duty cycle.

The increase in bandwidth simplifies the multi-connection mode.

Compatible with previous Bluetooth specifications.

The performance of BER (bit error rate) has been further improved.

To put it simply, the speed at which things are transmitted is different.

If you buy a call headset.

Nothing big of a difference.

Hello, I have seen your question and am sorting out the answer for you, please wait a moment.

Hello, 1. 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.

2. 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. 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.

I hope mine is helpful to you, I wish you a happy life, if you are satisfied with the answer, please give a thumbs up in the lower left corner of the evaluation, thank you
