The supplier(of the original chip antenna) notified Raytac in March 2026 that the original chip antenna has reached its end-of-life (EOL) status, thus the introduction of an alternative(new) chip antenna from the same supplier to ensure long term supply continuity.
There are no changes on Form, Fit, Function, and Quality of Reliability. Only change in Chip Antenna Appearance.
Upon receiving this notice, our R&D team promptly conducted comprehensive validation. The results confirm that there is no impact on RF performance, EMC compliance, or related certifications.
In conclusion, all existing certifications and technical documentations remain valid.
The change is already effective as the existing inventory of the original chip antenna has been depleted. All production batches are already using the new chip antenna.
We kindly invite our customers, distributors, and partners to update your records accordingly. For any questions or support, and further document requests regarding this update, feel free to reach out to Raytac Sales Team via: sales@raytac.com.
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
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.
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.
To help you quickly get started with Raytac’s AN7002 Wi-Fi module and nRF5340 module, here’s a simple guide on how to set up the development and programming environment using AN7002Q-nRF5340 Demo Board(AN7002Q-DB-5340)and nRF5340 DK.
