Bluetooth 5.3, Bluetooth 5.2, Bluetooth 5.1, Bluetooth 5.0: what are the differences

we will explain what’s new in Bluetooth 5.3 and its differences from previous versions, so you can understand how the new Bluetooth 5.3 innovates and improves compared to previous versions. We’ll start with the list of Bluetooth versions and what’s new in each, then we’ll continue with the differences and what’s new in version 5.3.

Here you need to remember two things. The first thing is that when you connect two devices via Bluetooth, the improvements and technologies of the device with a lower version are used. Thus, by connecting a Bluetooth 5.3 mobile to a Bluetooth 5.2 speaker, you only have the improvements of 5.2. In addition, each new version integrates the improvements of the previous onesso you won’t have to choose between one and the other, just look for the most modern version on your future devices.

Evolution of Bluetooth version by version

We will start with a list in which we will teach you all the versions that the Bluetooth protocol has had and its main novelties. In this way, you will not only be able to see the different versions and their release dates, but you will also be able to evaluate the importance of the novelties of each version having the context of how much each of them has innovated.

Bluetooth is still the reference wireless communication protocol between devices, which makes it possible to connect computers, smartphones, tablets, and various types of connected devices such as watches, keyboards, mice, speakers. All of this without the need to use cables to connect themand using a secure radio frequency in the 2.4 GHz ISM band.

  • Bluetooth 1.0: This was the first version released in 1999, and precisely because it was the first stage of the technology, it had many connectivity and security issues. It is currently in disuse.
  • Bluetooth 1.1: It was the first update of Bluetooth 1.0, and it arrived in 2002. It is already a mature and commercial version with a transmission rate of approximately 721 kbps.
  • Bluetooth 1.2: The second update of Bluetooth 1.0, which arrived in 2003 and reduced the interference that still existed in version 1.1 to finish tweaking the technology.
  • Bluetooth 2.0: The second major version of Bluetooth arrived in 2004, although compatible with 1.2. Its main feature was the introduction of the Improved data throughput(EDR or Enhanced Data Rate), which allowed it to offer a transmission rate of just over 2 Mb/s.
  • Bluetooth 2.1: The next version released in 2007, which kept the same transmission rate as its predecessor. However, it did introduce a feature that changed Bluetooth forever, the ability for one device to add another and connect automatically without needing a PIN or anything like that.
  • Bluetooth 3.0. This release came in 2009 and brought with it the term or HS surname for High Speed. It was a big improvement in the transmission rate, which could reach 24 Mbps.
  • Bluetooth 4.0: This is perhaps one of the most important versions of the standard, since it began to combat the excessive battery consumption of technology using Bluetooth Low Energy. The version arrived in 2010, maintained the transfer rate of 24 Mb/s and thanks to its low consumption, it began to be used in smaller and less powerful devices.
  • Bluetooth 4.1: It arrived in 2013, and was characterized by targeting before anyone else the IoT (Internet of Things) world by allowing connection between small devices without intermediaries.
  • Bluetooth 4.2: This next update came in 2014 and implemented the IPv6 protocol to allow direct connection to the Internet.
  • Bluetooth 5.0: Mid-2016, the big revolution arrived, a new step forward that doubled the transfer rate, quadrupled the range, continued with the low-power thinking of IoT and enabled more data in each message transferred . As for the numbers, the transfer rate reached 50 Mb/s and the range reached 240 meters.
  • Bluetooth 5.1: The new version that arrived in 2019 revolved around location, allowing devices to know the location of other devices they are connected to within a few centimeters. You will also be able to identify the direction from which the signal you are looking for is coming from.
  • Bluetooth 5.2Also known as Audio LE Bluetooth: This is a standard published in early 2020, and which improves the sound quality and energy efficiency of all connected devices for audio functions. It uses a new codec, the Low Complexity Communication Codec (LC3), which can compress and decompress transmitted data more efficiently, and allows audio to be transferred to multiple devices at once.
  • Bluetooth 5.3: Announced in July 2021, although it only started to be available in May 2022. This version offers lower power consumption in use, connections with less interference, better connection security and better quality at all times, depending on the bandwidth required. Small details to keep polishing it.

Bluetooth 5.3 compared to its predecessors

You could say that Bluetooth 5.0 is the basis of the new version family of this protocol. This is the latest major update that has revolutionized Bluetooth 4, doubling the speed of file transfers and quadrupling the range, which is how far they can transfer data between each other. Since then, the other versions have only perfected small things.

Bluetooth 5.1 it focuses on device location, letting them know the location of other devices it is connected to and identify the direction its signal is coming from. Meanwhile, ** Bluetooth 5.2 focuses on soundimproving the sound quality and energy efficiency of all devices that connect for audio functions.

Bluetooth 5.3 is also another small step for this family of Bluetooth 5 updates, in this case focused on further improve energy efficiency, and make the connections have less interference. Moreover, he hears offer a higher level of security and better quality at all times, depending on the bandwidth required.

To improve performance by reducing power consumption, this release added a filter for periodic advertising process updates. This makes shipments Redundant data is removedand therefore save the small peak of energy consumption necessary for their delivery

Chains

In addition to this, devices can give their list of favorite channels for the device connecting to it to take them into account and use them above others. A) Yes, performance is improved and connection interference will be reducedsince the channels are not decided by a single device such as the mobile, but they can be said to come to an agreement to use the paths that work best for both.

For security reasons, the control of the size of the encryption key is increased. This means that now the driver can set a minimum size for the key, and if you are going to connect to a device that is not very secure due to using too short an encryption key, the connection will not be not established to protect you. In this way, consumption is also reduced, since the device only “looks” at those who meet the requirements when it comes to offering to connect to it.

Finally, Bluetooth 5.3 allows your devices andsand modes with higher bandwidth if needed, and with minimal delay. This means that if we use Bluetooth in a way that suddenly requires more bandwidth, like switching from listening to music to calling, that transition will be more efficient.

There is also a function IntelligentDualBluetooth which allows simultaneous connections to be established, both in its normal state and in BLE. This is quite an important novelty, as it will allow, for example, connect two mobiles to a single speaker via Bluetoothas long as all three devices are running 5.3.

Therefore, we can say that this release focuses on consumer and privacy polish, and all of this internally, so you won’t need to change the configuration or anything. However, it also includes the new Smart Dual Bluetooth featurewhich can offer you an interesting new feature.

Here, what you need to know is that each new standard also offers improvements from previous versions. This means that when buying a device you won’t have to choose between 5.2 sound or 5.3 improvements, just try to make your Bluetooth version the highest as it will include all new features that previous versions implemented. .
