Thank you Ibrahim and Amanda.

I was able to successfully run and validate the STA (station) example provided in the nRF Connect SDK.

For my setup, I am using the nRF7002-EK in combination with the nRF54L15-DK over an SPI interface. To get the example working correctly, I had to make a few minor modifications and configuration adjustments, outlined below:

MAC Address Update
I replaced the default MAC address in the app.overlay file with the correct MAC ID corresponding to my nRF7002-EK module.
Memory Configuration Adjustments
I modified the following parameters in the prj.conf file to better fit the available memory constraints:
- CONFIG_HEAP_MEM_POOL_SIZE=32000 (reduced from 37000)
- CONFIG_NRF_WIFI_CTRL_HEAP_SIZE=16000 (reduced from 20000)
- CONFIG_NRF_WIFI_DATA_HEAP_SIZE=32000 (reduced from 40000)
CMake Argument Addition
I added an extra CMake argument to specify the correct shield:
- -DSHIELD=nrf7002eb2
Hardware Connections
The physical wiring between the boards was completed according to the provided diagram.

5. Program Output
The system runs successfully, and the output is as follows:

So if we would like to plug&play, we'll go for the nRF7002 EB II. If we want to write your own dts overlay and Kconfig, nRF7002-EK works just fine though.

It's possible. The nRF7002 EB II has the connect port designed for nRF54L15DK to avoid the connection issue, and there are some configs for nRF54L15DK working with nRF7002 EB II in this sample, such as https://github.com/nrfconnect/sdk-nrf/blob/v3.2.2/samples/wifi/sta/sample.yaml#L101-L103

Thank you for reply, Amanda H.

Thank you for your reply.

I will follow the suggestions you provided.

However, I would like to clarify one of the main questions along withe other questions from my previous message. Is it not possible to use the nRF7002 together with the nRF54L15? I have already designed a custom board using these two chips.and will get PCBs soon.

Also, could you please explain why it is necessary to purchase the nRF7002 EB II?

Thank you for your guidance.

Kind regards,

KIran

Hi,

Please contact your regional sales manager to obtain an nRF7002 EBII for nRF54 devices. See the sample Requirements.
