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.

    Hi, 

    However, the test result was only 2MB per second.

    Just to confirm first, are you talking about megaByte or megabit?

    This is the test result.

    I see.

    Well first of all, you are using the EB here, which is connected using SPI, as opposed to on the nRF7002DK (which the DevAcademy was used with) which uses QSPI. The throughput is about 4 times lower with SPI. Though I agree that what you are getting here still looks a bit low.

    I can try this myself later this week. Are you able to try this on a nRF7002DK and compare? (Given that you have one available)

    Regards,

    Elfving

    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.

    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.

    If you measure that the HTTP file service implemented on the nrf7002EBⅡ can achieve a higher network speed, it will be of great help to our project. Thank you.

    Hello. Besides, I have another question.Is the nrf54lm20 capable of accessing the flash via the sqspi interface?

    If possible, are there any corresponding documents or examples? At present, we haven't found a suitable sample.I hope to receive your reply. Thank you very much for your help.
