Bluetooth 6.0 – Learn more about Bluetooth channel sounding
The Bluetooth Special Interest Group introduced its latest Bluetooth version 6.0 later this year. This will bring major updates over recent incremental updates, delivering significant enhancements to audio streaming, device networking, and especially location services. Some of the most significant impacts of these new features are enhanced security and greater accuracy in distance measurement.
Overview of the upgrades:
- Bluetooth channel sounding
- Decision-based advertising filtering and advertiser monitoring
- ISOAL enhancement
- LL extended feature set
- Frame space update
Bluetooth channel sounding
The new Bluetooth Channel Sounding feature makes it possible to create products capable of calculating the distance between two Bluetooth devices with far greater accuracy than could ever be achieved using the first generation RSSI and path loss method. It works in a completely different way and includes a number of security safeguards that mitigate different types of risk. Bluetooth channel sounding is expected to benefit Find My solutions, digital key products, and many other Bluetooth-connected devices.
Unlike AoA and AoD, which require multiple antennas, increasing the chip's footprint, and can suffer from performance issues in multipath environments, Bluetooth® channel sounding will introduce a new method for achieving accurate distance estimates known as phase-based ranging (PBR).
In phase-based ranging, an accurate estimate of the distance between the two radios is obtained by analyzing the phase of the radio signal. Essentially, the time of flight of the radio signal, i.e. the distance between the two devices, is accurately measured using phase data.
To measure the phase data, both devices alternately transmit and receive in a coordinated manner. This is repeated several times on different frequencies (channels), which resolves ambiguities and improves accuracy, even in the presence of reflections (multipath), such as in indoor environments.
Products include Bluetooth 6.0 – new nRF54 series
Nordic Semiconductor continues its commitment to innovation with its new fourth generation low power wireless SoCs. With support for Bluetooth® 6.0 and future Bluetooth® specifications, as well as LE Audio, Bluetooth® Mesh, Thread, Matter, and more, the nRF54 series will be the foundation for a new wave of revolutionary IoT end products. The nRF54H20 and the nRF54L15 are the first System-on-Chips (SoCs) in the nRF54H and nRF54L series, the "H" branch of the wider nRF54 series. This SoC is ideal for disruptive IoT applications that require high processing power, excellent energy efficiency, and state-of-the-art security.

The nRF54L15 DK is the development kit for all three wireless SoC (System-on-Chip) options in the nRF54L Series. The nRF54L15 sits on the development board, while the nRF54L10 and nRF54L05 can be emulated. The affordable single-board development kit makes all features of the wireless SoC available to the developer.
The nPM1300 Evaluation Kit allows for simple evaluation and code-free configuration of the nPM1300 Power Management IC (PMIC). By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM1300 can easily be configured through an intuitive GUI and exported as code to be implemented in your MCUs application.
The nRF7002 DK is the development kit for the nRF7002, and nRF7001 Wi-Fi 6 Companion ICs. It contains everything needed to get started developing on a single board. The DK features an nRF5340 multiprotocol System-on-Chip (SoC) as a host processor for the nRF7002.
The Power Profiler Kit II (PPK2) is a standalone unit, which can measure and optionally supply currents all the way from sub-uA and as high as 1A on all Nordic DKs, in addition to external hardware.
The Nordic Thingy:53™ is an easy-to-use IoT prototyping platform. It makes it possible to create prototypes and proofs-of-concept without building custom hardware. The Thingy:53 is built around the nRF5340 SoC, our flagship dual-core wireless SoC. The processing power and memory size of its dual Arm Cortex-M33 processors enables it to run embedded machine learning (ML) models directly on the device.
The Nordic Thingy:91 X is a battery-operated prototyping platform for cellular IoT based on the nRF9151 System-in-Package (SiP) supporting LTE-M, NB-IoT, GNSS and NR+, and certified for global operation. It is the ideal platform for rapidly developing a prototype for any cellular IoT concept, and is especially suited for asset-tracking applications. Nordic Thingy:91 X enables location tracking using cellular (MCELL and SCELL), Wi-Fi, or GNSS, in combination with nRF Cloud Location Services.
The nRF9151 DK is an affordable, pre-certified single board development kit for evaluation and development on the nRF9151 System-in-Package (SiP) for LTE-M, NB-IoT, GNSS and DECT NR+. It has a dedicated LTE-M, NB-IoT and DECT NR+ antenna that supports a wide range of bands to operate globally.
