Raytac and onceLabs Deepen Collaboration with Live Demo of Mobile‑to‑Embedded Bluetooth Channel Sounding

A LinkedIn debut becomes a live showcase at Embedded World North America with
Raytac’s Bluetooth LE module solution and Google Pixel 10
.

[Anaheim, CA — November 2, 2025]
At embedded world North America — Raytac Corporation, a global leader in wireless modules, together with onceLabs, a U.S.-based global Nordic Design Partner specializing in custom embedded and mobile application software, will present a live demo of Bluetooth Channel Sounding. The demonstration showcases the accuracy and potential of the new Bluetooth 6.0 feature by combining Raytac’s Nordic-based nRF54L15 (AN54LQ-15) module with a Google Pixel 10 smartphone.

Bluetooth Channel Sounding adds a new dimension to wireless connectivity by combining secure data transfer with the low‑power, low‑cost Bluetooth technology already trusted worldwide — now extended to deliver precise location awareness. This evolution means IoT devices can gain both communication and ranging capabilities in a single, efficient platform. With tens of centimeter distance accuracy, Channel Sounding enables practical new use cases such as secure access, proximity‑based services, indoor navigation, and ‘Find My’ functionality.

Android 16 now supports Channel Sounding APIs, making it possible for developers to access this capability directly on flagship devices like the Pixel 10. With anticipated pervasive adoption across the mobile ecosystem, Channel Sounding is positioned to scale broadly and become a standard feature for IoT applications.

The onceLabs demo was reported as the first of its kind in August, gaining notability on LinkedIn(Post link) — and is now being shown for the first time in a public venue. onceLabs’ free BLE Hero app(Download Link) is a sniffer, analyzer, and development tool, available in app stores, and can be seen in action during the live demo. The Android version has been updated to capture and display Channel Sounding data, giving developers clear insight into ranging accuracy and system performance. Since 2018, Raytac and onceLabs have collaborated to bring new Bluetooth capabilities from specification to market‑ready solutions. Raytac’s proven hardware platforms and onceLabs’ application‑layer software expertise combine to accelerate adoption of emerging standards, showing how partnership can translate advanced technology into product‑ready functionality.

“Our collaboration with onceLabs has always been about enabling customers to move quickly and confidently with the latest Bluetooth technology,” said Lyon Liu, CEO of Raytac Corporation. “This live demo of Channel Sounding is another example of how our partnership delivers not just modules, but complete solutions that inspire new applications.”

Together, Raytac and onceLabs are demonstrating how Bluetooth Channel Sounding can move from specification to practical demonstrations that product companies can act on.

“With Raytac providing the hardware foundation and onceLabs delivering the application software, we continue to support customers in translating new Bluetooth features into real use cases,” said Joseph Bakalor, President and CTO of onceLabs. “Channel Sounding is a perfect example — and with our expertise in Zephyr RTOS, developers can build on open, production‑ready software that scales from prototype to deployment.”

The Raytac + onceLabs demo will be featured in Raytac Booth 5067 at embedded world North America, November 4–6, 2025, at the Anaheim Convention Center. Attendees are invited to visit the booth to see the demo in action and learn how Raytac and onceLabs can support their next wireless product.

Software Kits Resource & Preparation
Download nRF Connect For Desktop (Please Click Me)
Download nRF Command Line Tools (Please Click Me)


Preparation
1. Prepared with the latest version of nRF Connect for Desktop and Select version Windows 64-bit – 5.1.0
2. Prepared with the latest version of nRF Command Line Tools and Select version Windows x86 64-10.24.2
**Note: SEGGER J-LINK Upgrade message might pop up while you’re doing above download.

 If you’re initiating Segger Embedded Studio (SES) application, please check the guideline here(Click me) 

3. Locate all the necessary kits for programming in PC (Check Software/Application list)


Get started with building your program

Intro: The development tool of nRF Connect SDK(NCS) equipped with free VS (Visual Studio) Code IDE for firmware compile and programming.
Note: it is highly recommended to apply NCS 2.8.0 for advanced features of nRF54L15.

Step 1 —- Activate your “nRF Connect for Desktop”  >> “Toolchain Manager” >> “Open” >> “Install”


Step 2 —- You will find multiple options of NCS V x.x.x in the tool, we’re using NCS v2.8.0 as example to run sample code of nRF54L15.


Step 3 —- Make sure the NCS v2.8.0 is installed at same directory with compiling system. (the root of Open VS Code) (This is using C:\ncs  as example.)


In case to organize the files, do “Select directory’” and “Confirm”.


Step 4 —- After nRF Connect SDK v2.8.0 Download ready , go “Open VS Code”.


Step 5 —- Go “Open Existing Application” , and activate example code: Bluetooth > peripheral_uart


Step 6 —- Moving to program build & compiling by selecting dev kit: nrf54l15dk/nrf54l15/cpuapp


Step 7 —- You will get a .hex file after the above programming compiling process.


Step 8 —- Functions are available for during the code compiling process under “ACTIONS” in VS Code IDE
<< Build >>


<< Debug >>


<< Flash >>


Firmware Programming
It is feasible to do the firmware programming using nRFConnect SDK (NCS) tool.
Developer may use “Programmer” to do the firmware flashing with the candidate .hex file.

Step 1 —- Execute nRF Connect for Desktop >> Programmer >> Open


 “Select Device”


Select ”nRF54L15 DK


“Add File”


Step 2 —- Select the candidate .hex file

Select “Erase & Write”


It indicates the programming process is on the way↓


The firmware programming process is done after seeing “Completed” in system Log field.


Step 3 —- Use the mobile App to make sure the Bluetooth broadcasting is functioning after the firmware flashing process is successfully done to the module.


D. Channel Sounding Preview

What is Channel Sounding? —- Advance the “Find My” feature into next level accuracy
Have you ever concerned about the distance accuracy when you’re using RSSI to get the distance between devices and to evaluate the transmission distance with legacy Bluetooth module?
Nordic NRF54 solution has taken us into next level with Channel Sounding feature that achieves the “centimeter-level” distance accuracy. Early implement achieves 10-20cm in the record.

Credit: Bluetooth Alliance


How does Bluetooth Channel Sounding work?
Bluetooth Channel Sounding implemented with Phased-Based Ranging (PBR) & Round-trip time (RTT)(the concept idea of TOF time of flight) algorithm to achieve a higher precision of measuring distance between 2 devices.

Phased-Based Ranging (PBR):
Signal has been sent between initiator and reflector with multiple frequency to increase measuring accuracy.

Credit: Bluetooth Alliance


Round-trip time (RTT): It’s the concept of utilizing TOA (Time of arrival). Using TOD(Time of departure) & TOA to measure the timing during the packet transmission between devices.

Potential applications:
Personal item finding
Secure access control
Smart lock system
Digital Key
Asset Tracking
