1. Hardware Set Up

Hardware Kit on hand:

• 1 x Nordic nRF5340-DK: PCA10095(2.0.2)
• 1 x AN7002Q-DB-5340-M
• 1 x IDC Ribbon Wire(J-Link Cable)
• 1 x USB Wire –Type C USB
• 1 x USB Wire-Micro USB

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.

!! 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).

Raytac's nRF7002 module: AN7002Q series Wi-Fi module have obtained Wi-Fi Alliance CID

 [2025.02.19]

Raytac Corporation is proud to announce that our application for Wi-Fi Alliance (WFA) certification on the AN7002Q series(based on Nordic's nRF7002 IC) has been successfully approved. This achievement reinforces our commitment to providing high-quality, reliable, and standard-compliant wireless solutions.
By leveraging this certification, our modules ensure seamless interoperability, enhanced security, and superior performance for a wide range of IoT applications.

Advantages of Using Raytac Modules with WFA Certification:

Reliable and Secure Connectivity – Ensures seamless communication with other Wi-Fi-certified devices while meeting industry-leading security standards for stable and secure data transmission.
Faster Time-to-Market – Pre-certified modules simplify compliance processes, reducing development time.
Global Market Access – Certification helps meet regulatory requirements in multiple regions, expanding business opportunities.
Significant Cost-Saving – Compared to the chip-on-board approach, using Raytac’s Wi-Fi module allows direct access to the Derivative programs(please click here for more descriptions), leveraging Raytac’s CID to minimize certification costs and save time-to-market.

Step-by-Step Guide to Purchasing MAC Addresses from IEEE for Your Devices

The Ultimate Guide to Acquiring MAC Addresses from IEEE 

FAQ: How to write MAC address into the OTP memory of Raytac’s AN7002Q Wi-Fi module/AN7002Q-DB-5340 DevKit

Recently we have received the FAQ: how to write MAC address into the OTP memory of AN7002Q-P Wi-Fi module? In this article, we’ll get this question explained to give customers a more smooth experience using the AN7002Q-nRF5340 Demo Board(AN7002Q-DB-5340).

Is there an existing Wi-Fi MAC address in the AN7002Q part on the DevKit?

Currently, the AN7002Q module on Raytac’s AN7002Q-DB-5340 board isn’t loaded with a Wi-Fi MAC address.


When running Wi-Fi Scan code/Station code/Shell code…etc. on NCS v2.6.0 (and later versions), the AN7002Q module must have a programed Wi-Fi MAC address to function properly.

Therefore, it’s necessary to follow the below process:
1. Program the original Wi-Fi radio test code (..\nrf\samples\wifi\radio_test) into the MDBT53 section,
2. Then write the Wi-Fi MAC address in to the AN7002Q section via command.

After this, program the original Wi-Fi Scan code/Station code /Shell code … into the 5340, and it will function properly.

*Raytac will assign 2 MAC addresses(for both 2.4GHz & 5GHz) to every AN7002Q module.

*If customers don't have MAC addresses for DevKit development yet, please reach out to service@raytac.com

Case study 1. SCAN code example

Scenario:
Following error occurred when building the SCAN example code, flash it onto the AN7002Q-DB-5340 board, and run the test.

Solution:

When running Wi-Fi scan code on NCS v.2.6.0 or later version, the OTP memory in the AN7002Q module must have a Wi-Fi MAC address programmed in for the Wi-Fi scan functionality to work properly.

(Note: OTP is a One-Time programmable memory, which means the value can only be written once.
The customer must aware of this before performing the OTP operation.)

1. Program the original Wi-Fi radio test code (..\nrf\samples\wifi\radio_test) into the MDBT53 section,
then manually input and execute the following OTP read command.

wifi_radio_ficr_prog otp_read_params

If you see both MAC0 and MAC1 display a value of 0xFF, as shown in above, it means that you haven’t written the Wi-Fi MAC address into the AN7002Q’s OTP.

2. Manually issue the OTP write command to write the Wi-Fi MAC address into the OTP.

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/radio_test/ficr.html

wifi_radio_ficr_prog otp_write_params 0x120 0xDDCCBBAA 0xFFEE

wifi_radio_ficr_prog otp_write_params 0x128 0xDDCCBBAA 0xFFEE

After you complete the above, use the OTP read command in below to check if the Wi-Fi MAC address value was written.
The MAC0 and MAC1 should display the value you’ve input from the OTP write command.

wifi_radio_ficr_prog otp_read_params

3. Program the original Wi-Fi SCAN code back into the MDBT53, the Wi-Fi scan functionality should work properly.

==================================================================

Case study 2. Shell code example

SDK Wi-Fi example test – Running Shell Code on AN7002Q-DB-5340:
Scenario:
An error occurs while running Shell code on AN7002Q-DB-5340.

Solution:
The AN7002Q-DB-5340 is paired with nRF5340 DK for development,
but neither of the 2 boards has an external MX25R64 (Serial NOR Flash) component.
So far, only the nRF7002DK board is equipped with the MX25R64.

Therefore, while running the original Wi-Fi shell code, the program will enable SPI NOR.

When using AN7002Q-DB-5340, you should add CONFIG_SPI_NOR=n in the prj.conf file to disable SPI NOR, to turn off any configurations related to it.

After recompiling and flashing, the shell code function
( e.g., Wi-Fi scan/Wi-Fi connect/net ping ..) should work properly.
