Raytac’s Impact on the Zephyr Ecosystem – Little Module, Huge Potential

發表於 由撰寫發表留言

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.

We invite you to explore more about how Raytac supports the Zephyr ecosystem and discover our range of development kits and modules designed for seamless integration.

Essential Tips for nRF54L15 HEX File Verification

發表於 由撰寫發表留言

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.

Before building your own .hex file on Raytac’s nRF54L15 modules(Product link), please configure some settings(shown below) in advance.

In VS Code:

  1. Go to Add Build Configuration
  2. Find System Build (sysbuild) ➝ Choose Build System Default
  3. 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.

For more details behind this suggestion, please refer to the Nordic DevZone link below.
https://devzone.nordicsemi.com/f/nordic-q-a/120313/how-to-modify-the-name-of-the-merged-hex-file


Suggested path:
1. ..\nrf\samples\bluetooth\application-name\build\merged.hex

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! 😊

How to use Raytac’s MDBT50Q-CX-40 dongle as a BLE sniffer?

發表於 由撰寫發表留言

Introduction

Uncertainties in Bluetooth Application Development
Bluetooth’s growing popularity comes with challenges during development. Common issues include hardware instability, software incompatibilities, and environmental interference.
Accurate issue identification and resolution are keys to successful development.

Common Uncertainties
Unstable Connections: Disruptions from wireless signals or physical obstacles.
Pairing Failures: Devices unable to establish connections.
Data Errors: Packet loss or corruption during transmission.
Compatibility Problems: Protocol version mismatches affecting interoperability.

Efficient Bluetooth Issue Analysis
Challenges like transmission speed limitations, data loss, connection failures, or protocol violations can arise. As Bluetooth signals travel wirelessly, precise analysis requires specialized tools.
Nordic offers firmware integrated with Wireshark, flashable onto the Raytac MDBT50Q-CX-40 Dongle, enabling engineers to capture and analyze Bluetooth broadcast signals via USB.
This setup streamlines issue identification and resolution.
Below’s how to configure the Dongle for Wireshark reception.


Flashing Firmware into MDBT50Q-CX-40
Step 1: Download and extract the nRF Sniffer for Bluetooth LE from Nordic:
https://www.nordicsemi.com/Products/Development-tools/nRF-Sniffer-for-Bluetooth-LE
Step 2: Locate the file: sniffer_nrf52840dongle_nrf52840_4.1.1.hex
This is the firmware to flash into MDBT50Q-CX-40.


Step 3: Press and hold the button on MDBT50Q-CX-40 and plug it into a PC USB port.
Bootloader mode will be activated after the LED light is turned on.
Then flash the firmware using nRF Programmer.

Step 4: Open the nRF Programmer and follow the below steps:
Select the Device:


The device will appear as the name shown in below:


Add Firmware File:


Load sniffer_nrf52840dongle_nrf52840_4.1.1.hex into the Programmer:


Press “Write" to flash the firmware.
After flashing, press “Select Device" again.
If the Device name appears as nRF Sniffer for Bluetooth, the flashing is successful.


Set Up Wireshark Software Environment
Step 1: Download & install nRF-Util: https://www.nordicsemi.com/Products/Development-tools/nRF-Util
Step 2: Open MS-DOS and use the command nrfutil list to check if the ble-sniffer item is available.
If not, install it using nrfutil install ble-sniffer.


Step 3: Download and Install Wireshark: https://www.wireshark.org/download.html.
Step 4: Open Wireshark and navigate to: Help → About Wireshark → Folders.
Step 5: Locate the string under Personal Extcap Path for the extcap directory, which will be an empty folder.


Step 6: Copy the files from nrf_sniffer_for_bluetooth_le_4.1.1\extcap (downloaded earlier) into Wireshark\extcap directory.


Step 7: After reopening, you should see an interface with a configurable icon next to the dongle.


Step 8: Edit → Configuration Profiles → Import → From Directory → Navigate to the directory nrf_sniffer_for_bluetooth_le_4.1.1\Profile_nRF_Sniffer_Bluetooth_LE and click “Select Folder".


Step 9: The profile will be imported. Click OK to confirm.


After all the above is done, the setup shall be completed.


Capturing and analyzing Bluetooth packets
After launching the program, you can see the following devices and Dongle settings.
Double-click to start the packet capture process:


If you want to capture packets with PHY=125K, you can use the following settings:


Packet Analysis Method
In Wireshark, select the device from the “Device" menu to capture and analyze broadcast packets.

User Cases – What sniffer can offer
1. Disconnection when transmitting over 20 bytes between Tablet and Raytac’s AT-Command Module:
Through sniffer analysis, it was discovered that Raytac’s module requested a packet length of 251 bytes, but the tablet’s TX setting was limited to 27 bytes.


2. Broadcast Device Name containing invisible characters:
The device could connect using a mobile app but failed to connect using Central’s code.
From the sniffer interface shown below, the device name length is 11, but the Length field shows 13.
The actual data length (Type length + Device Name) = 1 + 11 = 12, indicating an issue with the program’s broadcast name length.


3. Incorrect parameter settings causing issues with throughput or packet reception:
Improper settings can lead to reduced throughput, incorrect data reception, or disconnections.
The diagram below shows a correct setup with high-volume data transmission. The Protocol Length is 251, and the data transmission intervals are consistent, achieving optimal throughput.


Summary
Mastering hardware and software setups and effectively using packet analysis tools can boost development efficiency and enable high-performance Bluetooth applications.
