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.

Raytac’s Impact on the Zephyr Ecosystem – Little Module, Huge Potential

In this article, Stanley Huang, MSc, Deputy Manager of Firmware Development at Raytac, shares insights on how Raytac’s modules and development kits strengthen the Zephyr ecosystem.

[Stanley Huang, New Taipei City]
When we talk about open-source platforms like Zephyr RTOS, most people immediately think of major chip manufacturers such as ST Micro, NXP, or Nordic. But to me, what truly makes Zephyr famous amongst the developer community is through modules that developers can actually touch: those they can instantly plug in and start using right away. In these terms, Raytac is one of the most underrated and important contributors in this ecosystem.

Raytac Modules Make Zephyr More Accessible
Instead of being a chip vendor, we specialize in producing high-quality, globally certified modules – especially Bluetooth and Wi-Fi modules based on Nordic chipsets, such as the AN7002Q, AN54LQ, AN54LV, MDBT53, MDBT50Q, and MDBT42Q.
All these modules are already certified with Regional RF compliances(FCC, IC, CE, KC, etc.) and the latest Bluetooth Specifications, offering developers the assurance of “plug and play” and “production-ready” solutions.
We assure that our modules have become one of the easiest platforms for Zephyr developers to test BLE functionality.

I paired Zephyr with Raytac’s MDBT50Q-DB-40 development board when I first applied Zephyr in a BLE Peripheral project . With a simple west build -b nrf52840dk_nrf52840 followed by flashing the firmware using J-Link or nRF Connect for Desktop, the BLE beacon immediately showed up on my phone. Clean, simple, noise-free, and developer-friendly – that’s Raytac’s style.

Modules play an invaluable role in product development
Many would say Raytac only makes modules and the real core is still Nordic’s SoC.
But I believe that in an open-source system like Zephyr, the hardware that helps your project runs first is that which contributes the most.
Our Zephyr-registered development kits eliminate the hassles of manual soldering, regulatory certification, and antenna design, allowing engineers to fully focus on developing applications based on Zephyr.
They can run Zephyr’s BLE peripheral, central, GATT, and HCI samples directly on the Raytac kits that act as a one-stop hardware solution.
In many ways, Raytac has pushed Zephyr’s usability a significant step forward.

Raytac Also Expands Zephyr’s Application Horizon
Many of Raytac’s modules are ultra-compact- ideal for wearables, smart sensors, and low-power beacons…etc. These are the scenarios where Zephyr excels, and Raytac’s modules provide the physical platform to enable companies to build their “dream devices".
When running Zephyr on a tiny module like the AN54LV-15(Product Link), developers will be amazed that something smaller than a piece of corn kernel can run a full RTOS, manage the BLE stack, trigger timers, drive I2C sensors, and even connect to the cloud, all by itself.  This combination doesn’t just make development easier – it inspires developers to realize that: “they can build their projects using Raytac’s hardware.”

Raytac may not be the star, but we’re always ready for you
On Zephyr’s main stage, companies like Nordic, STM, and Intel take the spotlight, but Raytac plays an essential supporting role – supporting the performance from behind the scenes. We offer stable, high quality, and low-power platforms, giving every line of Zephyr code a place to run and every feature a cornerstone.
Our greatest value lies in helping developers skip antenna design and RF interference concerns – so they can jump right into the Zephyr ecosystem with ease.

Our products deliver the reliability you need and the efficiency you expect.

We invite you to explore more about how Raytac supports the Zephyr ecosystem and discover our range of development kits and modules designed for seamless integration.

Understanding LE Audio: BIS and CIS Explored

LE Audio, introduced with Bluetooth 5.2, brings significant advancements to audio technology by using the Low Complexity Communication Codec (LC3). Compared to older codecs like SBC, LC3 provides better audio quality while reducing power consumption, making it ideal for devices like wireless earphones and hearing aids.
In this article, we’ll explore two key modes in LE Audio: Broadcast Isochronous Stream (BIS) and Connected Isochronous Stream (CIS). These modes cater to different use cases, offering flexible audio experiences.


What is Broadcast Isochronous Stream (BIS)?

BIS enables one-way audio broadcasting from a single source to multiple devices simultaneously without pairing.
Several BIS streams can form a Broadcast Isochronous Group (BIG), allowing synchronized multi-stream transmission, ideal for environments where many users need access to the same audio content, such as events or museum tours. Any device that supports LE Audio can receive the broadcast, making it an accessible and versatile solution for shared audio experiences.


Here’s a chart including BIS and BIG:


Example Use Case: Concerts and Events
Imagine attending a large outdoor concert where BIS technology is used to broadcast live music directly from the stage to the audience’s devices, such as smartphones and wireless earphones. BIS can broadcast live music from the stage directly to attendees’ devices, ensuring everyone hears the performance in real-time, regardless of location.

Example Use Case: Museum Tours
In a museum setting, Broadcast Isochronous Stream (BIS) can be used to deliver audio guides directly to visitors’ smartphones or rented devices. Visitors can receive synchronized audio guides on their smartphones, enriching their experience and offering multi-language support.


What is Connected Isochronous Stream (CIS)?
CIS focuses on direct, device-to-device connections. The audio stream is transmitted between paired devices with two-way communication, creating a connected and dedicated audio experience.
It’s ideal for personalized experiences like hearing aids or wireless earphones. Multiple CIS streams can be synchronized using a Connected Isochronous Group (CIG) for simultaneous audio transmission while maintaining the benefits of a personalized connection.


Here’s a chart including CIS and CIG:


Example Use Case: Wireless Earphones
Imagine a user connecting their wireless earphones to a smartphone via CIS. When two Bluetooth earphones are connected simultaneously, multiple CIS streams can be grouped into a Connected Isochronous Group (CIG) to achieve synchronized audio transmission across both devices and also enables high-fidelity audio streaming, ensuring clear and immersive sound.
With CIS, each user can adjust volume or equalizer settings independently without impacting others, creating a truly personalized listening experience. CIS provides a significant upgrade over traditional Bluetooth audio by delivering richer sound quality with lower latency.

Example Use Case: Hearing Aids
Connected Isochronous Stream (CIS) is especially beneficial for hearing aids, allowing individuals with hearing impairments to directly connect their devices to a TV, smartphone, or other audio sources. CIS enables real-time adjustments to improve speech clarity or reduce background noise, ensuring the audio is clear and effective. Users can have a closer and more immersive audio experience, which is crucial for enhancing social interactions and supporting daily activities.


How BIS and CIS are grouped into BIG and CIG

Summary


BIS vs. CIS: Which Fits Your Needs?

  • BIS is suitable for shared audio experiences, such as public events and guided tours, where multiple users need simultaneous access.
  • CIS is designed for personalized audio, offering low-latency and high-quality sound for individual users or synchronized multi-device setups.

LE Audio is set to change everyday audio experiences with richer, more versatile audio solutions. Whether it’s concerts, museums, or hearing aids, BIS and CIS provide innovative ways to enhance audio quality and efficiency.

Step 1. Execute the combine batch file in bootloader (nrf52840_bootloader_setting_merge.bat) and generate file of nrf52840_bootloader_secure_combin_settings.hex :

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin
set BS= nrf52840_bootloader_secure_settings.hex
set BL= nrf52840_xxaa_s140.hex
set BSBLCombind= nrf52840_bootloader_secure_combin_settings.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %BS% %BL% -o %BSBLCombind%
pause


Step 2. Create a Final.hex file by 3-in-1 batch file(nrf52840_3in1_merge.bat)
※Note : This hex file is created for the production line to pre-load firmware into modules prior to shipment.

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Users\user\Desktop\Nordic BLE\nRF5_merge tools\nRF52 bin
set SD= s140_nrf52_7.2.0_softdevice.hex
set BLT= nrf52840_bootloader_secure_combin_settings.hex
set APP= nrf52840_xxaa.hex
set SD_BLT=SD_BLT.hex
set Finalfile=Final.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %SD% %BLT% -o %SD_BLT%
pause
mergehex.exe -m %SD_BLT% %APP% -o %Finalfile%
pause


Step 3. Create a DFU(OTA).zip file of nrf52840_xxaa.zip
※Note : This zip file is created for end device DFU(OTA) implementation.

nrfutil pkg generate –hw-version 52 –sd-req 0x100 –application-version 0xFF –application
nrf52840_xxaa.hex –key-file private.pem nrf52840_xxaa.zip

The DFU OTA zip file will be derived.

※Note :
The “0x100" appeared in the above DOS code(in red font) is the FWID(Firmware ID) for s140_nrf52_7.2.0_softdevice.hex;
FWID can be found from the soft device documents on the Nordic website.



Step 4: Run DFU OTA (On mobile in this example)


4A. Install the nRF Connect APP on mobile, with DFU OTA file: nrf52840_xxaa.zip. (Download link)


4B. Send nrf52840_xxaa.zip via email to mobile device after combination is done on PC, then download it.


4C. Open nRF Connect APP and run connection;


4D. Execute DFU and select “Distribution packet(ZIP)", thus starting the DFU OTA process.


4E. Start DFU OTA → exit the APP after DFU OTA is completed → restart the mobile device.

Secure DFU OTA for nRF52840 solution modules: Guide to create hex/zip file for implementation – #2(Application)

Following up-Part A: Bootloader (Click for article link)

We will be focusing on:

in this article.

IC: nRF52840
DK: PCA10056 (for nRF52840)
SDK: 17.1.0
Softdevice: s140_nrf52_7.2.0_softdevice.hex
IDE: Keil C
PC: Win 10


Path: nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_uart\pca10056\s140\arm5_no_packs

Before building Application code , some amendments need to be made regarding DFU-related settings and code inside Application:

Step 1.


1A. Add code in definition in C/C++ :
BL_SETTINGS_ACCESS_ONLY NRF_DFU_SVCI_ENABLED NRF_DFU_TRANSPORT_BLE=1
(Total 3 steps definitions need to be set up)


1B. Add “include path” in C/C++


1C. Add the .c files inside red frame in (Screenshots 1 & 2)
and the 2 groups of (nRF_DFU & nRF_SVC)(Screenshot 3) under Project(Screenshot 4)



1D. Add code into main.c file in Application (..\examples\ble_peripheral\ble_app_uart\main.c)
(Please refer to: main.c file at: ..\examples\ble_peripheral\ ble_app_buttonless_dfu)


1E. The code of file: sdk_config.h (..\examples\ble_peripheral\ble_app_uart\pca10056\s140\config\
sdk_config.h) inside Application needs to be modified.


1F. Adjust the IRAM1 value in Target after implementing DFU service:
Check on the IRAM1 Value of *p_app_ram_start to be modified from default: 0x20002AE8 0x3D518 to 0x20002AF8 0x3D508, as shown in the red frame in the bottom right corner.
In this case, the program should run successfully.


1G: Create a file of: nrf52840_xxaa.hex after building application code files.


Step 2. Create a bootloader setting file of nrf52840_bootloader_secure_settings.hex : (via DOS)

nrfutil settings generate –family NRF52840 –application nrf52840_xxaa.hex –application-version 3 — bootloader-version 2 –bl-settings-version 1 nrf52840_bootloader_secure_settings.hex –no-backup


※Stay tuned for #3 – Part C: Combining and merging built files in the next article,

scheduled release in next week(05/06/2024).
