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 numberbelow. )

RF testing is performed using UART TX/RX commands. The SDK program defaults to certain positions, but users can modify these two pin positions according to their product design without changing the Baud Rate setting.

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.
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.

Raytac's pre-certified module for your convenience - but how?
So, in this post, we would like to take you on a little journey through most of the important certifications that Raytac has pre-certified their modules with.
The exact topic is actually what you need to know and what that means to you as a Raytac customer.
Obviously, each and every certification has their own rules, so that's how we're going to do this - one by one.
FCC - (U.S.A.)
Most people in the industry have heard of FCC, but for you who really don't know what it is, it's the Federal Communications Commission in the United States of America. Although considered as a center for these regulations, you will soon realize that they're not really the center of these regulations and laws at all.
So for the FCC certification, you can as a Raytac customer:
Use Raytac's certification ID directly on your finished product's label
But you need to:
Test FCC Part 15B EMC for your finished products
IC - (Canada)
When it comes to the Industry Canada (yes, that's what IC stands for), the regulations and procedures are much like their sibling FCC.
Use Raytac's certification ID on your finished product's label (same as FCC)
But, just like FCC, you need to:
Test IC ES003 (EMC)
This can be combined together with the FCC Part 15B test
TELEC - (Japan)
TELEC, sometimes referred to as MIC, is surprisingly simple.
What you will need to do is:
Use Raytac's certification ID on your finished product's label
Yes - you can actually just go right ahead and implement and/or commercialize your product after its parts are all proven TELEC certified which is pretty neat. However, there is another test that you as a customer can do if you wish, and that is VCCI which is just like the EMC tests mentioned above with the only difference (in terms of regulation) is that it's NOT mandatory. Thus, you can choose not to do it as well.
KC - (South Korea)
As for the Korean regulation, these are the things you will have to do:
Test EMC for wireless (KN301489 - same as CE's EN301489)
Test EMC for wire (IO port) (KN3235)
If, and only if, your final product is equipped with IO ports, that is.
These two tests needs to be done locally (Korean test lab) and depending on which test it is, you'll have to deal with them differently.
Firstly, for the wireless test, you can refer to Raytac's own certification report so that the lab knows the module itself has passed although it still needs to be tested.
Secondly, the for wire (IO port) test, you will have to do from scratch essentially.
Thus, even though we have applied for KC for our modules, you will still have to test them locally.
CE (Radio Equipment Directive 2014/53/EU (RED)) - (EEA, Europe)
Although CE is considered as strict regulation, the procedure is pretty simple. Simply put, you will have to conduct tests on a few different samples, and the procedure goes:
Test on Conducted engineering sample (EN300328)
You can refer to Raytac's test report, if the test lab accepts it, that is.
To ensure that they do, you can choose to conduct your tests at the same lab as Raytac - SGS.
Test on Radiated engineering sample (EN300328)
Test EMC (EN301489)
Test Safety (EN60950)
Subject to change to EN62368 in 2021
SRRC
Simply put, you will have 2 scenarios:
Your end product can either be defined as a "Home Appliances" or an "Office Utilities" product
Then you can simply refer Raytac's SRRC ID (module policy just like FCC/IC/TELEC)
Your end product is neither of the above
You have to apply for your own SRRC ID by testing everything required by the regulation
NCC
They go by a "Platform policy" which basically means that as long as you are just adding functionality onto an already existing feature, then you can leverage Raytac's NCC ID on your product's label directly (module policy just like FCC/IC/TELEC/SRRC). Otherwise, you will have to apply for a new one.
Thus, the procedure becomes:
Adding functionality of an already existing feature (a.k.a. platform)?
Then you can simply refer Raytac's NCC ID on your product (module policy just like FCC/IC/TELEC/SRRC)
New ideas/features?
Sorry, you have to apply for your own NCC ID by conducting all tests necessary
RCM
Australia's RCM (Regulatory Compliance Mark) is a lot like CE, much like IC is similar to FCC.
When applying to this certification, you will be in either of these two circumstances:
CE already done.
You can refer to your own CE certification and ask your test lab to copy the report to your RCM application.
CE NOT done.
You must conduct the test from scratch. But it is a whole lot like CE, meaning:
Test on Conducted engineering sample
Test on Radiated engineering sample
Test EMC
Test Safety
Bluetooth Certification
Last, but definitely not least, is the Bluetooth Certification. For this one, choosing Raytac's modules will bring you great benefits. But first, you need to:
Apply for Bluetooth SIG's "Adopter Membership" (free)
For your first product, that is all you will have to do. But what if you come up with a new model of the product? Before you ask, I will answer "No - you don't necessarily have to purchase another DID." In order for this to be true though, your new product cannot have either of these things changed:
Hardware
Unless you are still using Raytac's module
Feature
Unless you are still using Raytac's module
Brand Name
Brand name remains unchanged.
Although you might be able to apply for these certifications all on your own without trouble whatsoever, we always encourage customers using Raytac's BLE modules to contact us before hand so that we can provide you valuable information. This way, you will get unbiased guidance which will save you time and money.
As always - Happy tinkering everybody :)
Hi there, folks! Here introduce the hardware setting perspective to burn your firmware onto MDBT50Q-RX Dongle.
(if you are looking for firmware coding setting, please visit "Firmware Coding & DFU onto MDBT50Q-RX")
So you have hopefully downloaded your IDE, you have written your code which you then plan to copy it over onto your MDBT50Q-RX and make it execute your master plan to take over the world!
Seriously, don't underestimate the Nordic nRF52840 based MDBT50Q-RX. USB sticks with Bluetooth can do wonders ;)
So, first of all, in order to be able to burn your code onto the USB Dongle, you will have to know the nerdy parts which includes which pins you will have to connect to. In our very well documented specification sheet for MDBT50Q-RX on section 8 which is called "Reference Circuit", you will find parts down to the left that has "3.3V/SWDIO/SWCLK/GND" marks on it:
Further down in the specification sheet, in section 9, you will find pictures illustrating where exactly on the PCB you can find these pins:
Now we know what to look for and where they are, so now we have only got to tell you how to use them.
Some people might not know this, but for developing these things, you need to get something called J-Link to connect your MDBT50Q-RX to your desktop. However, since this J-Link, when buying the official one from SEGGER, is very expensive, we strongly recommend you to just buy the nRF52840-DK from Nordic Semiconductor as it can be used as a J-Link through their software development kit (SDK) called nRFgo Studio and is MUCH CHEAPER than the official J-Link from SEGGER is.
Sidenote: There are a couple of other reasons why you should just get your hands on a nRF52840-DK from Nordic Semiconductor instead of getting a SEGGER J-Link, but that's not the topic of this post ;)
When this is done, this is finally how you connect your MDBT50Q-RX to your J-Link to make it all work:
Here you will have to pay attention to the fact that you have to connect J-Link pins 3, 5 & 9 to GND. Otherwise, you won't be able to burn anything onto your dear MDBT50Q-RX.
The physical connection should look like this:
Pay attention to the direction of the cable, because that will also matter. The direction we mean in this case is which way the slim strip of red is facing.
As we have just revised our MDBT50Q-RX, our customers who have been developing firmware for our USB dongle should take a look at our previous blog post in which we explain about the changes made or contact us directly at service@raytac.com
Have a good day and we at Raytac wish you smooth and happy tinkering :)
