[January 2026 Update]
In this article, we will talk about:
Project WITH External Flash MX25R64(8MB) applied
- Connecting through SPI between nRF5340 module: MDBT53-1M(BLE) & nRF7002 module: AN7002Q(WIFI)
- Connecting through QSPI (XIP) between MDBT53-1M and external memory MX25R64

1. Hardware Set Up
Hardware Kit on hand:
Note: Pease make sure to have both “Nordic nRF5340-DK” and “AN7002Q-DB-5340-M” connected and running during the WIFI+BLE (nRF7002+nRF5340) project development.
Hardware Network:
IDC Ribbon Wire(J-Link Cable): Connect nRF5340-DK to AN7002Q-DB-5340-M
USB Wire –Type C USB: Power supply to AN7002Q-DB-5340-M through USB TYPE-C
USB Wire-Micro USB: Power supply to nRF5340-DK through Micro USB
Schematic diagram of AN7002Q-DB-5340-M can be referenced for design as follows.

*nRF7002 module <- SPI -> nRF5340 module
*MX256R NOR Flahs <-QSPI-> nRF7002 module
!! Important Note:!!
The circuit of SW1(p1.08)/SW2(p1.09)/LED1(p1.06) on AN7002Q-DB-5340-M is NOT COMPATIBLE to Nordic WI-FI Control Pin of swctrl1(p1.08)/host_irq(p1.09)/grant(p1.06).
In this case, if you’re working with external flash MX25R64 for the WIFI project, Please avoid pin SW1/SW2/LED1 usage while LED2(p1.07) remains available as normal usage.
For the PCB design of end product/end device(mounted with AN7002Q & MDBT53 modules), the switch & LED should be configured to be SW1(p0.23)/SW2(p0.24)/LED1(p0.28).
A LinkedIn debut becomes a live showcase at Embedded World North America with Raytac’s Bluetooth LE module solution and Google Pixel 10.
[Anaheim, CA — November 2, 2025]
At embedded world North America — Raytac Corporation, a global leader in wireless modules, together with onceLabs, a U.S.-based global Nordic Design Partner specializing in custom embedded and mobile application software, will present a live demo of Bluetooth Channel Sounding. The demonstration showcases the accuracy and potential of the new Bluetooth 6.0 feature by combining Raytac’s Nordic-based nRF54L15 (AN54LQ-15) module with a Google Pixel 10 smartphone.
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.
