Enhanced Attribute Protocol (EATT)Bluetooth version 5.2 features an upgraded version of the original Attribute Protocol (ATT) called Enhanced Attribute Protocol (EATT). It offers better IoT connection as the range.Here’s everything you need to know about the three key features of Bluetooth version 5.2 and what they mean for device makers. It also ushers in the next generation of Bluetooth audio — LE Audio.Bluetooth 5 offers the flexibility to make IoT solutions better because of 2x speed, 4x range 8x data capacity. Version 5.2 offers new benefits for the next generation of wireless devices and audio technologies. At the CES conference in January 2020, Bluetooth introduced the latest version of Bluetooth technology — version 5.2. Standby Time: 300 hoursBluetooth ® has long been the industry standard for streaming audio applications and audio devices.

EATT is optional per the specification, and it requires an encrypted connection between both Bluetooth LE devices — making it more secure than ATT. It also reduces overall latency. This feature improves user experience in cases where multiple applications are running on the same Bluetooth LE stack. This way, transactions from two or more applications can be completed at the same time.

Alternatively, a transmitter can change the transmit power voluntarily and relay that information to the receiver.This ensures that both devices stay within their optimal signal ranges. A receiver with a signal strength that’s higher or lower than this optimal range can have issues decoding signals.With LEPC, a receiving device can monitor the received signal strength indicator (RSSI) signal of its partner device and request a change in the transmit power level in either direction. Wireless receivers have an optimal received signal strength range that provides the best signal quality.

When CISes need to be synchronized, for instance when left and right earbuds play audio, they’re linked together in a Connected Isochronous Group (CIG). Connection-oriented communication: In this mode, each data stream is referred to as a Connected Isochronous Stream (CIS). Isochronous channels can be used on any of LE’s physical layer variants: 1M, 2M, and LE Coded configurations S=2 and S=8, and they support both connection-oriented and connectionless communication: Isochronous Channels (ISOC)In a major upgrade from Bluetooth Classic and earlier versions of LE, Bluetooth version 5.2 also supports isochronous channels. What’s more, power management with LEPC also improves coexistence with other signals in the 2.4 GHz band, including signals from WiFi and Zigbee.

Just like with CIGs, devices with Bluetooth 5.2 can create multiple BIGs.Bluetooth version 5.2’s new isochronous channels support data retransmission for CIGs and BIGs, but in different ways. In this case, each stream is called a Broadcast Isochronous Stream (BIS), and each group of BISes is called a Broadcast Isochronous Group (BIG). Connectionless communication: In this mode, a single source like a smart TV can stream data to multiple synchronized streams. Additionally, CIGs enable bidirectional data transfer so it’s easier for devices to send control data to the source device. Devices with version 5.2 can also create multiple CIGs.

ISOC serves as the foundation for LE Audio and Bluetooth LE’s new audio codec LC3 (Low Complexity Communications Codec).LE Audio noticeably improves on Bluetooth Classic and Bluetooth LE. LE AudioWith ISOC, device makers can build products that stream audio to multiple users, and even in multiple languages, with crystal clear sound. ISO intervals, the intervals at which “events” occur, can range from 5 milliseconds to 4 seconds. With BIGs, on the other hand, only the master sends a packet in each subevent.

Since LC3 has multi-stream capabilities and supports multiple synchronous connections by default, True Wireless users can enjoy faster pairing and much better battery life.The future of hearing aid technology also looks bright thanks to LC3 and LE audio. According to Bluetooth SIG, LC3 also sounds much better than SBC, Bluetooth Classic’s standard codec.Bluetooth version 5.2 and LC3 will revolutionize how consumers use Bluetooth audio accessories. This refines sound quality and extends handset battery life, two key benefits for audio device manufacturers.LC3 optimizes Bluetooth LE’s existing codec by compressing audio transmissions and scaling them down to very low bit-rates, all without compromising audio quality.

Bluetooth 5.0 Specs Series Is Designed

This multiprotocol RISC-V-based series is designed for maximum performance and optimizes a wide variety of applications, from indoor positioning and Bluetooth Mesh to OpenThread. The new TLSR9 chip series from Telink supports the latest Bluetooth standards — version 5.2, EDR, BR, and LE — and can power the future of audio devices. Take Bluetooth ® Version 5.2 to the Next LevelBluetooth version 5.2’s new features open up many new opportunities for audio device manufacturers, but they’ll need the right SoC solution to unlock what this technology has to offer. Also, LC3 is low power and energy-efficient, enabling manufacturers to build smaller, more discreet hearing aids that last longer on a single charge.
