FAQ for BLE and Regulatory Certifications with EZ-BLE modules - KBA213976
Where can I find resources to understand BLE qualification and certification if EZ-BLE modules are used in our product?
There are two knowledge based articles on this topic from Cypress: “Process for Qualifying a Bluetooth Product - KBA210711“ and “Queries on BLE Qualification and Declaration Processes - KBA210802”. You may also go to the Bluetooth SIG website for more details about qualification and certification.
Question: Where can I find the RF Regulatory certification-related details for EZ-BLE modules?
Answer: For each certified module, there is knowledge-based article (KBA) that includes the test reports and RF certifications. They can be found on cypress.com. The EZ-BLE Modules are fully certified for FCC, ISED (formerly IC), CE, MIC/TELEC and KC. The following table lists the compliance of the module to regulations across various regions.
|North America||USA, FCC Part 15.247 and Canada, IC (RSS-247 Issue 1)|
|Europe||ETSI (EN 300 328), EN 60950-1, CISPR/EN 55022, EN 55024 & EN 301 489-1/17, EN62479|
|Japan||MIC Notice No.88 Annex 43|
|South Korea||KC 2013-157 & 2013-116, KN 301 489-1&-17|
Question: Where can I reuse the regulatory certification from EZ-BLE modules on our end products?
Answer: If EZ-BLE module is the only RF transmitter in the product, different regulations have different policy on whether to reuse the certification in the end product:
For FCC, you may reuse a module certification, however, the end product still needs to go through the FCC 15 subpart B test. ISED/IC for Canada follows FCC practice.
For CE, all the conducted test cases of EN300328 can be inherited from the modules test report. Any radiated test cases under EN300328 or ESD test cases under EN301489 must be tested with end products
End customers can reuse the modular approval of EZ-BLE modules in Japan or South-Korea. No further RF testing is needed for the end product when it uses a certified module.
All system level tests like ESD, EMC and SAR, when required, should be tested with the end products.
Question: Are EZ-BLE modules certified for Austrian/New Zealand market?
Answer: No, EZ-BLE modules are not certified for Austrian/New Zealand market. The Australia/New Zealand radio regulations do not provide a modular approval policy similar to the United States (FCC) and Canada (ISED/IC). However, EZ-BLE modules’ CE test reports can be used in part to demonstrate compliance in accordance with Radio communication (Short Range Devices - SRD Standards）2014.
To meet overall Australian/New Zealand final product compliance, the end product developer must construct a compliance folder containing all relevant compliance test reports e.g. RF, EMC, electrical safety and DoC (Declaration of Conformity) etc. It is the responsibility of the integrator to know what is required in the compliance folder for ACMA compliance or New Zealand Radio communications.
Question: Are EZ-BLE modules certified by SRRC (State Radio Regulatory Commission) in Mainland China?
Answer: We have not done SRRC certification for our EZ-BLE modules. SRRC only allows certain product categories, which include computer, home appliance and office equipment, to inherit the module’s SRRC certification and go through EMC test only, if the end product includes a SRRC-certified module. However it’s up to SRRC to determine whether a specific product falls into these categories or not. End products in other product categories are required to go through the complete tests regardless whether a SRRC-certified module is used or not.
Question: Do EZ-BLE modules have CCC (China Compulsory Certification)?
Answer: CCC is required for end products only in China. Module is not listed in the CCC product catalog (http://www.ccc-cn.org/en/Catalogue.html).
Question: Are EZ-BLE modules certified by NCC in Taiwan?
Answer: No.In Taiwan, NCC (National Communications Commission) approval is required for the end product using EZ-BLE modules. In-country testing is required since FCC/CE certifications are not accepted. FCC will be the reference standard for certification regulations. The probability of getting EZ-BLE modules certified by NCC is high as EZ-BLE modules are already FCC certified.
Question: Have you performed SAR (Specific Absorption Rate) tests with EZ-BLE modules?
Answer: No SAR tests has been done with EZ-BLE modules as SAR is required for the end products. Different countries have different SAR policies. In general, for 2450MHz signal, SAR limit and exemption in general use with head and trunk can be referred to the following table:
There is a KBA of RF regulatory certifications for each EZ-BLE module. AMPE test report is included in the test reports attached to each KBA. Some FCC certificates show that "the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons." Based on the MPE test result, the power level with our EZ-modules can meet the SAR exemption limits at less than 5mm.
Question: Which antenna can be used with the CYBLE-202007-01 module when completing BT SIG qualification and RF regulatory certifications?
Answer: The CYBLE-202007-01 module is designed to work with a standard 2.2 dBi dipole antenna. Any antenna of equivalent or less gain can be used without additional application and testing for FCC/IC regulations. The following table details approved antenna for the CYBLE-202007-01 module antennas.
Question: For the CYBLE-202007-01 module, do I need to redo Bluetooth SIG qualification testing if a different type of antenna is used, or if an antenna with higher than 2.2dBi gain is used?
Answer: You do not need to redo the Bluetooth SIG certification with a new antenna as the RF-PHY test in Bluetooth SIG certification is not related to antenna gain.
Question: For the CYBLE-202007-01 module, do I need to redo regulatory certification, such as FCC, if a different type of antenna is used or if an antenna with higher than 2.2dBi gain is used?
Answer: For FCC and IC, any new antenna type (i.e. not dipole) or an antenna with higher gain will require a Class II permissive change and a completed EMC test report or RF exposure evaluation. For other regions outside of FCC and IC, there are no clear instructions on how to handle an antenna type change or antenna gain increase. Please contact Cypress with any specific questions on the target regulatory certification and we will check on a case-by-case basis.
