BLE 5.2 Training } BLE 5.3 Training
Some analysts are claiming the technological advances in Bluetooth Low Energy 5.2 (BLE 5.2) are as great as the differences between 5G and its predecessor 4G.
Very simply, BLE 5.2 marks a new era of Bluetooth.
For one thing, the Enhanced Attribute Protocol (EATT) baked into Bluetooth Low Energy 5.2 is a pretty remarkable upgrade version of the original Attribute Protocol (ATT). For example, where the original unenhanced Attribute Protocol operates in a sequential manner, the Enhanced Attribute Protocol provides a way to perform concurrent/parallel transactions between a BLE client and a server and potentially reduce the latency of operations in some applications.
This standard uses a new codec, the Low Complexity Communication Codec (LC3), which can more efficiently compress and decompress the data transmitted via Bluetooth.
This is an improvement over the SBC, which was the current generic Bluetooth codec. With this, you can have a better sound quality with a much higher efficiency.
The spotlight on Bluetooth Low Energy 5.2 version falls squarely on its LE Isochronous Channels (ISOC). This feature, which was primarily designed to support LE Audio, the next generation of Bluetooth audio, allows the communication of time-bound data to one or more devices for time-synchronized processing.
It can be used over connections or be broadcast to an unlimited number of devices in a connectionless fashion. New use cases and topologies are made possible by LE Isochronous Channels.
With Bluetooth Low Energy 5.2, larger amounts of information can finally be transmitted over lower bandwidth and at lower power. Essentially, this is achieved through the new LC3 codec, which results in information being more compressed on the input side, but being decompressed on the output side much more efficiently.
This is big news for those who want high quality Bluetooth audio, as that fidelity is going to be able to be much greater. The audio information is able to compress much smaller – which saves time and energy – but not lose any quality due to the efficiency and speed of the decode on the other side.
