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.
Hi readers, did you know that Raytac offers a special service exclusively for our customers? 😉 We offer support services: HEX file verification and flashing firmware into modules per customer’s requests. Compared to the series nRF52 and nRF53’s 2 in 1 or 3 in 1 merged hex files, nRF54L15 requires something slightly different. Following are the tips and suggestions.
Find System Build (sysbuild) ➝ Choose Build System Default
Click Generate and Build
Starting from NCS v2.8.0 (including later versions), the .hex file can be generated in two different paths. 1. ..\nrf\samples\bluetooth\application-name\build\merged.hex 2. ..\nrf\samples\bluetooth\application-name\build\application-name\zephyr\zephyr.hex
Using the AN54LQ/AN54LV series as an example: When you provide the programming file (.hex) for production, please ensure that the file is taken from the following path: 1. ..\nrf\samples\bluetooth\application-name\build\merged.hex And we also do not recommend renaming the merged HEX file due to Nordic suggestions.
Not recommended path: 2. ..\nrf\samples\bluetooth\application-name\build\application-name\zephyr\zephyr.hex The zephyr.hex file is not recommended to be used for flashing or verification in the production process.
Thank you all for your patience in reading! Best wishes for your projects – your success is Raytac’s success! 😊

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
