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.
The Bluetooth SIG Board of Directors(BoD) has granted its approval for a 15% increase in member fees, effective from January 1,2024. This decision comes after careful consideration of the organization’s financial situation and the need to cover the rising costs of current and futrue member services throughout 2024.

For protecting against National Security Threats reason, FCC newly announced a new request added in Equipment Authorization program. FCC Publication Number: 986446. date:01/24/2023
FCC amends the rules related to equipment authorization program to prevent any unacceptable risk result from communications networks and supply chains from equipment. DA/FCC #: FCC-22-84. FCC Amends Equipment Authorization Program require applicants for certification need to provide a written and signed attestation. Also, any equipment certification needs to identify a agent, located in United States for service or the process.
Raytac Corporation has pointed US subsidiary, Raytac USA LLC., poses as the US agent for Raytac Corporation to fulfill the FCC new requirements. Customers has any issues to adopt this new regulation may contact Raytac for further support.
nRF51422 is the first solution supports both Bluetooth and ANT+, different from pure Bluetooth Low Energy BLE solution, nRF51822 released earlier. The edge cutting technology enable nRF51422 suporting multiprotocol concurrency capable for both Bluetooth Low Energy and ANT+. At the same time Nordic released SDK S310 for nRF51422 which is a combined peripheral BLE and ANT+ protocol stack that supports concurrent operation and all ANT+ features.
When Nordic moved to nRF52, started from nRF52832, the game changed. Even nF52832 still supports ANT+, the technology support such as SDK releasing or developers’ forums, has moved to direct supported by ANT+ Wireless (formerly Dynastream Innovations). Since then, Raytac suggest developers who is interested in ANT+ product still able to select the modules based on core specification and form factor, but access the firmware development support from ANT+ directly. Developers who are interested to know more about ANT+ is encouraged visit ANT+ FAQ support page first for more information about membership, development, resource and certification.
All Nordic nRF52 solutions supports ANT+ feature, developers may refer to below Raytac module map and find what the protocol supports by the symbol stated besides the Nordic solution indication.
Outside the home in the frozen world. Raytac take care!
Winter is coming and field is chilly. Stay home enjoy the warm is what people is looking for.To ensure users enjoy the joyful time on couch, Raytac conduct a 72 hrs non-stop connection reliability test under -40°C which is compliant with industrial standard. The significant result shows there is no any single packet lost over 252,979,200 bytes (244 bytes/Packet).
Raytac today introduces that Bangalore, India based partner and solution provider, Atoll Solutions Pvt Ltd., has released a BLE beacon feathers way-finding, tour-guide, environment sensing, motion sensing and asset tracking.
Atoll’s BLE beacon deploy Raytac’s MDBT42Q series of modules which employ Nordic nRF52X deliver the ideal platform to for building low-power & long-life BLE beacons. The beacons are available for B2B customers in a variety of form factors e.g. lanyard hook and tile. The beacons are built to be robust, and have been tested as a part of the Atoll Kinesis indoor location tracking platform.
“Raytac Bluetooth module provides an optimal and stable RF efficiency which easy the hardware design resource Atoll need. The compact size, stable quality and pre-certified modules also offer an advantage to speed up time to market efficiency and minimal the BOM cost." says Jithu Niruthambath, Co-Founder & CEO at Atoll Solutions.
Bluetooth applications not always tough and complicated.
Most cases, Bluetooth applications are brief and require simple bridge functionality only such as UART service for Bluetooth Low Energy (BLE) or SPP for Classic Bluetooth (BT3 or BT2). Raytac adopted Nordic nRF52 base line solutions (nRF52805 / nRF52810 / nRF52811 / nRF52820) offer a series of base line modules with different form factor and antenna options for selection.
Excepting modules, Raytac even developed a firmware pre-loaded modules for base line solution which is called as AT command module series. AT command module collected a list of most common command that transparent transmission may need. A well developed firmware pre-loaded modules bring developers or customer a quick access to Bluetooth. Simply deploy the module onto applications and projects can be benefited with the maximum flexibility, design free, time saving advantage.
Raytac would like to announce Product Change Notice (PCN-19121601) for all nRF52832 module lines include MDBT42Q / MDBT42 / MDBT42V series.
There is no panic for this PCN, it is refer to module’s appearance changes only but no others. Raytac will remove YELLOW DOTmarking on shielding for all modules produced based on Nordic nRF52832 (Build Code: EXX) V.2 SoC since 2020 (Date Code from 001).
In case there is anything unclear for this PCN , please do not be hesitated to contact Account Manger for further assistance.
