Raytac has advanced the dev kit version of bundle offer – WIFI+BLE: AN7002Q-DB- 5340-M with an on-board flash memory(MX25R64) to create easy evaluation for Wi-Fi project developments.
[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

Hardware Set Up A. Project WITHOUT External Flash MX25R64 needed B. Project WITH External Flash MX25R64 needed
Software Resources & Preparations
Firmware Build & Compile A. Project WITHOUT External Flash MX25R64 needed B. Project WITH External Flash MX25R64 needed
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 (Click on the image to zoom in.)
!! 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).
Step 1: Prepared with the latest version of nRF Connect for Desktop, using Windows 64-bit – 5.2.0 Step 2: Prepared with the latest version of Command Line Tools, using Windows X86 64 – 10.24.2
**Note: SEGGER J-LINK Upgrade message might pop up while you’re doing above downloads.
Step 3: Locate all the necessary kits for programming in PC
3. Firmware Build & Compile After you download and set up nRFConnect SDK (NCS), you will be able to apply free VS (Visual Studio) Code IDE as firmware programming tool.
The below example uses NCS v3.1.1 and runs the program under: C:\ncs
Step 1: Start with a Wi-Fi Scan project and run the program under: C:\ncs\v3.1.1\raytac <<Create a new application and Copy a sample>>
Step 2: Select SDK v3.1.1 to copy the sample
Step 3: Select example by entering keyword: wifi scan(Wi-Fi Scan)
Step 4: Enter application location: C:\ncs\v3.1.1\raytac and name the project as: wifi_scan_uart_dfu
Step 5: Open an existing application and find the registered project: wifi_scan_uart_dfu
Step 6: How to activate the Devicetree setting of Wi-Fi nRF7002 and Create file:nrf5340dk_nrf5340_cpuapp.overlay Code example is as follows: / { chosen { aliases { /delete-node/ leds; /delete-node/ buttons; }; };
Step 7: It is required to do MCUBoot before working with DFU using External Flash Please do the code configuration in sysbuild.conf as following reference code.
SB_CONFIG_BOOTLOADER_MCUBOOT=y # DFU with UART SB_CONFIG_MCUBOOT_MODE_SINGLE_APP=n
# DFU with external flash SB_CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y
Step 8: It is required to doMCUMGR before working with DFU over UART Please do the code configuration in prj.conf as following reference code.
# Enable QSPI driver for Application CONFIG_NORDIC_QSPI_NOR=y
# Enable mcumgr DFU in application CONFIG_MCUMGR=y CONFIG_NET_BUF=y CONFIG_ZCBOR=y CONFIG_CRC=y
# Enable mcumgr management for both OS and Images CONFIG_MCUMGR_GRP_OS=y CONFIG_MCUMGR_GRP_IMG=y CONFIG_FLASH=y CONFIG_IMG_MANAGER=y CONFIG_STREAM_FLASH=y CONFIG_FLASH_MAP=y
# Configure MCUMGR transport to UART CONFIG_MCUMGR_TRANSPORT_UART=y CONFIG_BASE64=y
Step 9: Add with MCUBoot setting , and create a root for sysbuild ; Build with file mucboot.overlay & file mcuboot.conf
9A. To the File: mucboot.overlay &mx25r64 { status = “okay"; };
Step 10: Create a VERSION file by referencing the following code when testing DFU over UART. VERSION_MAJOR = 99 VERSION_MINOR = 0 PATCHLEVEL = 0 VERSION_TWEAK = 0 EXTRAVERSION =
Step 14: Generate a Merged.hex file after compiling the program
Step15: You can choose Build/Debug/Flash under ACTIONS during development << Build >>
<< Debug >>
<< Flash >>
Step 16: Go to ACTIONS >> Memory report to check the memory partitions.
Now you can see partitions available in the system. mcu_secondary has already been located in MX25R64 flash memory.
4. Test/Validate DFU Process & WIFI SCAN After the firmware programmed to MDBT53 module on board, we use the USB to UART adaptor board for connecting AN7002Q-DB-5340-M through: A. MCUMGR UART to PC and through: B. WiFi Scan UART to PC respectively. Note: We suggest you finish connecting A. and B. before running tests.
Now we can run the tests.
A. DFU over UART – Using AuTerm Program 1. We can locate Image version=V99.0.0 under the current VERSION file
It also indicates Image version: 99.0.0 in MCUmgr-Slot 0.
2. Try to modify the file version from V99 to V100 under VERSION file: VERSION_MAJOR = 100
VERSION_MINOR = 0
PATCHLEVEL = 0
VERSION_TWEAK = 0
EXTRAVERSION =
And go with “Pristine Build”
3. We’re about to run DFU over UART , Please DO NOT do “Flash” or “Erase”.
Proceed with “Force reboot”
4. It’s now Version 100.0.0 in Slot 0 under MCUgr ⭢ DFU over UART successfully done!
Before it was Version 99.0.0 in Slot 1 under MCUgr.
B. WIFI SCAN – PuTTY Console WIFI SCAN credentials can be located under PC Console – PuTTY.
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.
Find System Build (sysbuild) ➝ Choose Build System Default
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.
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! 😊
