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.
[08/14/2025, California, USA] To better support our customers in the United States, Raytac Corporation(USA) now offers inland domestic shipping and a local support team based in California.

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! 😊

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)
