What is the Wi-Fi speed of the nrf54lm20 + nrf7002EB2?

cumin

    When evaluating the hardware performance, we tested the WiFi speed of the nrf54lm20 + nrf7002EB2.However, the test result was only 2MB per second.I suspect there might be issues with the test code and related conditions. It may not have fully demonstrated the actual performance of the equipment.

     I have attached the test code. This has been modified based on the official tutorial demo. tutorial demo link:https://academy.nordicsemi.com/courses/wi-fi-fundamentals/lessons/lesson-3-wifi-fundamentals/topic/lesson-3-exercise-2/.I would like to know the actual WiFi speed that this device can achieve at present.Thanks.

    The following test results are for nrf7002EBⅡ and nrf7002dk.We have established an HTTP file transfer service for comparison, the download speed measurement results were obtained.

    I might be misunderstanding you here, but when I said nRF7002DK I meant that you could try the nRF7002 that is already on the board, because that is connected using QSPI. Is this test for an nrf7002EBⅡ connected to a nrf7002dk?

    Based on the current test results, the network speed of 7002EBⅡ is likely unable to meet our requirements. We may have to give up the advantage of larger RAM provided by nrf54lm20 + nrf7002EBⅡ.

    Note that you could theoretically use sQSPI for this, but I am not sure if we have the sw support for that as of now. Please contact a regional sales manager for nordic about a timeline for this if you are interested - though you can also ofcourse implement a sQSPI driver yourself as well.

    Do you explicitly need the nrf7002EBⅡ for these tests because you want to use it on an end product? You need to make some changes for it to support QSPI, both with sw and hw.

    Is the nrf54lm20 capable of accessing the flash via the sqspi interface?

    Could you expand a bit on this?
