Bluetooth Channel Sounding adds a new dimension to wireless connectivity by combining secure data transfer with the low‑power, low‑cost Bluetooth technology already trusted worldwide — now extended to deliver precise location awareness. This evolution means IoT devices can gain both communication and ranging capabilities in a single, efficient platform. With tens of centimeter distance accuracy, Channel Sounding enables practical new use cases such as secure access, proximity‑based services, indoor navigation, and ‘Find My’ functionality.
Android 16 now supports Channel Sounding APIs, making it possible for developers to access this capability directly on flagship devices like the Pixel 10. With anticipated pervasive adoption across the mobile ecosystem, Channel Sounding is positioned to scale broadly and become a standard feature for IoT applications.
The onceLabs demo was reported as the first of its kind in August, gaining notability on LinkedIn(Post link) — and is now being shown for the first time in a public venue. onceLabs’ free BLE Hero app(Download Link) is a sniffer, analyzer, and development tool, available in app stores, and can be seen in action during the live demo. The Android version has been updated to capture and display Channel Sounding data, giving developers clear insight into ranging accuracy and system performance. Since 2018, Raytac and onceLabs have collaborated to bring new Bluetooth capabilities from specification to market‑ready solutions. Raytac’s proven hardware platforms and onceLabs’ application‑layer software expertise combine to accelerate adoption of emerging standards, showing how partnership can translate advanced technology into product‑ready functionality.

“Our collaboration with onceLabs has always been about enabling customers to move quickly and confidently with the latest Bluetooth technology,” said Lyon Liu, CEO of Raytac Corporation. “This live demo of Channel Sounding is another example of how our partnership delivers not just modules, but complete solutions that inspire new applications.”
Together, Raytac and onceLabs are demonstrating how Bluetooth Channel Sounding can move from specification to practical demonstrations that product companies can act on.
“With Raytac providing the hardware foundation and onceLabs delivering the application software, we continue to support customers in translating new Bluetooth features into real use cases,” said Joseph Bakalor, President and CTO of onceLabs. “Channel Sounding is a perfect example — and with our expertise in Zephyr RTOS, developers can build on open, production‑ready software that scales from prototype to deployment.”
The Raytac + onceLabs demo will be featured in Raytac Booth 5067 at embedded world North America, November 4–6, 2025, at the Anaheim Convention Center. Attendees are invited to visit the booth to see the demo in action and learn how Raytac and onceLabs can support their next wireless product.

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.
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.
