Just about everyone agrees: The new Bluetooth Low Energy 5.2 version is amazing with technological advances way beyond its predecessors.
Bluetooth LE has changed dramatically since it was first introduced. Initially designed only with ultra-lightweight use cases in mind, Bluetooth LE 5.2 has expanded in complexity, scope, throughput capability, and security.
And now BLE in the 5.2 specification, adds a completely new use case (LE Audio) to its list of capabilities, as well as new changes to power control, attribute protocols, and multi-channel transmission.
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.
Additionally, an audio source can transmit audio for synchronized playback by small, private groups of devices (personal audio sharing) or to large collections of devices of unlimited sizes in public spaces, such as cinemas.
One of the truly remarkable products coming from LE Audio is the Bluetooth hearing aid. Hearing aid devices require low and efficient power consumption. Being able to utilize BLE with its efficient power consumption characteristic, hearing aids are not only able to last longer on a single charge but manufacturers are also able to make these devices smaller and more discreet.
