Raytac Corporation 勁達國際電子股份有限公司 / Raytac Corporation (USA) / abietec Inc. A Bluetooth, Wi-Fi, and LoRa Module Maker/ODM & OEM Manufacturer based on Nordic nRF54; nRF53: nRF52; nRF51; nRF7002 Semtech Specification: SX1262
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.

When launching new products, there is a requirement for RF testing, and two methods are commonly used:
DTM (Direct Test Mode) and Radio Test.
Nordic’s SDK provides two RF testing programs: DTM (Direct Test Mode) and Radio Test. While both methods can test RF indicators, they have some distinctions. DTM follows the Bluetooth specification’s Direct Test Mode data format (referenced in Bluetooth Core Specification Version 5.2, Vol. 6, Part F.), primarily for Bluetooth certification tests.
On the other hand, Radio Test focuses on the chip’s radio indicators, making it more suitable for FCC and ETSI certifications.
Let’s delve into detailed explanations for DTM and Radio Test programs.
DTM(Direct Test Mode)
The Bluetooth Association offers a feature for testing RF characteristics. Nordic has incorporated DTM firmware into the SDK according to SIG standard documents. Customers only need to modify the Baud Rate and UART TX/RX pins to conduct RF tests.
1. Download and install nRF Connect for desktop software and nRF5 SDK from the Nordic website.
2. Install the Direct Test Mode program in the nRF Connect for desktop software.
3. Extract the SDK package, open the DTM example code from
nRF5_SDK_vxx\examples\dtm\direct_test_mode\ board number\blank, modify TX and RX pins based on the target board’s definitions, then compile.
Download the program to the target board connected to the PC. (Select the appropriate sample code based on the IC/module for testing, referring to the board number below.)

NRF52811
pca10056e
NRF52833
pca10100
NRF52820

4. Use nRFConnect DTM for testing by adjusting UART TX/RX pins.
Nordic provides a tool for simpler RF testing, allowing the configuration of radio-related data such as TX power, frequency, TX carrier, and TX modulation carrier through a Command List. It doesn’t include testing for RX sensitivity; if needed, users must either write a program for this test or use DTM for testing.
1. Open from nRF5_SDK_vxx\examples\peripheral\radio_test\board number\blank (Based on the IC/module for testing, referring to the board number below.)

2. This test also utilizes a Command-based approach to send instructions for different parameter tests. Compared to DTM, Radio Test is more flexible, offering a wider range of RF parameters to test. The connection method between the target board and PC, serial port modifications, and the approach with DTM are identical.
3. Use the command-Line interface (CLI) through the serial port to control and test the output power, bitrate, and channel settings of the radio parameters during testing.
Additionally, configure the CLI to enable the 32 MHz high-frequency crystal oscillator.
The application allows setting scanning mode with intervals ranging from 1 millisecond to 99 milliseconds (per 1 millisecond) for each channel.
4. Refer to the Nordic CLI commands documentation for the command testing method.
SRRC, or the State Radio Regulation Committee, is a mandatory certification required by the National Radio Management Committee of the Ministry of Industry and Information Technology of China. All wireless products sold within China must obtain certification, commonly referred to as SRRC certification, which involves approval of the wireless transmission equipment model.
SRRC Document No. 129:
Document No. 129 introduces various interference avoidance technical requirements for wireless transmission equipment, including “pre-transmission scanning," “monitoring and avoidance," and “Medium Utilization (MU)" for equivalent occupancy rate.
a. “Pre-transmission scanning" and “monitoring and avoidance" mechanisms involve monitoring and listening to the wireless channel before or during signal transmission. By setting appropriate detection threshold levels, the channel’s occupancy status is determined to select an idle channel for access.
b. The “equivalent occupancy rate" mechanism requires wireless transmission equipment to self-adjust based on parameters such as “Duty Cycle" and “transmission power," ensuring the “equivalent occupancy rate" remains at a lower level (not exceeding 10%).
1. Certificate Validity Period: Enforced from October 15, 2023. During this period, both old and new policies can be applied. Certificates obtained under the old regulation (Document No. 353) are valid until December 31, 2025. However, certificates obtained by complying with the requirements of Document No. 129 will be valid for 5 years.
2. Sample Requirements: 2.1 The quantity of conducted samples prepared according to the old regulation remains unchanged: 5 samples. 2.2 The major change introduced by Document No. 129 is the addition of interference avoidance technical requirements. The interference avoidance test items include: 1. Maximum channel occupancy time 2. Minimum channel idle time 3. Minimum silence period duration 4. Detection of unused signals 5. Detection threshold 6. Short control signal duty cycle 7. Equivalent occupancy rate.
You will get a brief understanding of WPC-ETA certificate (India) and how it relates to Raytac low energy Bluetooth module and how it helps you entering Raytac Bluetooth module into India by passing through importing and Customs clearance procedure way efficiently.
There are some types of ETA certificate categorized by the spec of your wireless transmission product (Bluetooth/Wifi/RFID and by device using frequency spectrum).
Hereafter we’re talking about the WPC-ETA compliance regulation to specifically on “Raytac’s low energy Bluetooth module.”
Outline of the article:
What is WPC Certificate/Equipment Type Approval (ETA) in India?
Raytac Bluetooth module applied to WPC-ETA Regulation Category
What is essential to get the ETA-SD license (ETA Approval)?
How the ETA-SD license works during importing process
A. What is WPC Certificate/Equipment Type Approval (ETA) in India?
The WPC (Wireless Planning & Coordination) is the broadcasting authority and is part of the Ministry of Communications and Information Technology in India.
Products with radio and/or wireless functionality imported or manufactured or marketed in India are required to have an Equipment Type Approval certificate (ETA certificate) from the Wireless Planning and Coordination (WPC India) Wing of the Ministry of Communications of the government of India. This includes product with Bluetooth, wireless local area network access technology (Wi-Fi), small digital radios (Zigbee), and radio frequency identification (RFID) and else more. The WPC-ETA certificate is required for anyone who wants to do wireless device business in India.
B. Raytac Bluetooth module applied to WPC-ETA Regulation Category
–ETA Through Self Declaration (ETA-SD License)
To specifically recognize what is the compliance regulation of equipment applies to Raytac Bluetooth module, we can be assured with our Bluetooth module spec located within “De-licensed Frequency Band list” , 2400-2483.5MHz / Limit with 10mW EIRP / Use of low power and very low power short range radio frequency device for Non-Specific Short range device, from the following chart which was released from WPC authority.
Once we confirm Raytac Bluetooth module spec is operated in De-License Frequency Band with low transmission power, at the mean time making sure the device is exempt from import license as per Import Policy of DGFT (Directorate General Of Foreign Trade), Ministry OM ETA-WPC-Policy-2018-19 dated 26th February 2019, free from EXIM Policy of DGFT, Raytac is granted to apply for “ETA Through Self-declaration” application procedure which was enabled by SARAL SANCHAR Portal of DoT on 12th April, 2019.
Here’s Raytac’s ETA through self-declaration (ETA-SD license) of module MDBT50 certified by WPC authority. (Please refer to the following image)
C. What is essential to get the ETA-SD license (ETA Approval)?
After getting idea of what ETA-SD license means to Raytac low energy Bluetooth module business, we need to get ready of the following points for applying the ETA Approval (ETA-SD License)
Applicant must be India manufacturing or authorized Indian representative
Making sure product exempt from import license
Making sure product working in the de-licensed frequency band
Wireless RF test report conducted by accredited laboratory
Details of Accreditation laboratory & Accreditation certificate issuing authority
Authorization letter
D. How the ETA-SD license works during importing process
Once ETA through self-declaration is generated for a model, subsequently it may be utilized by other person(s) for import/usage purpose in India. It is not necessary the importing agent/manufacturer is same party to the applicant of the license.
Question: How to import products falling under the category of ETA through Self-Declaration? Answer: Such category of product(s) may be imported by submitting an undertaking to the customs along with ETA-SD License without additional payment.
The ETA-SD license remains valid and NO renewal is needed until the technical parameter/design of the device is modified or altered.
Generally speaking , India doesn’t follow Modular policy nor Non-Modular policy. It determines how you proceed WPC-ETA certificate by product type (Semi-finished & End-product) and product technical spec (Frequency spectrum & Max output power). For instance: When the product is manufactured in India and its RF module(s) having ETA certificate is/are fitted inside it without any modification/alteration; then NO separate ETA is required for such finished product during import process. However, if finished product(s) are manufactured outside India, then ETA is required for each product before its import.
For the product which does not fall under De-Licensed frequency band and exempt from import license, WPC/ETA Certificate shall be obtained by routine proceeding to the concerned RLO ETA certificate. Both ETA (RLO) certificate and Import license shall be submitted to Customs during importing process whereas ETA-SD license Raytac module certified is exempt from import license that is way easier to proceed.
