Hello,

I see that most of your questions seem to be answered in the case already, but just to confirm:

[quote user=""]1. Has anyone successfully used the nRF9151 DK + nRF7002 EK combination?
[/quote]

The nRF9151dk is compatible with the nRF7002 ek which can be used for Wi-Fi locationing as the kit is Arduino Uno Rev3 compatible.

[quote user=""]2. Is there an official or recommended sample/project configuration for this setup?
[/quote]

I would recommend you to take a look at the following samples: Wi-Fi Shell, Wi-Fi Scan, Wi-Fi Shutdown, Cellular: location and Cellular: Modem Shell

These samples contain the necessary build commands and board targets with the shield.

[quote user=""]Are there any required Devicetree overlays or Kconfig options specific to this combination?[/quote]

Please refer to the overlay examples given here: https://nrfconnectdocs.nordicsemi.com/ncs/latest/nrf/app_dev/device_guides/nrf70/nrf7002ek_dev_guide.html

[quote user=""]4. Are there any known limitations with RAM/flash usage when combining LTE, modem libraries, Wi-Fi, TLS/cloud connectivity, and Zephyr networking on the nRF9151?
[/quote]

Full Wi-Fi cannot be run as there isn't enough Flash and RAM but Wi-Fi scan-only mode can be used.

[quote user=""]or would it be better to use a separate MCU for the Wi-Fi side and communicate with the nRF9151 over UART/SPI?[/quote]

That seems like a valid approach. We have the Thingy:91x where the nRF9151 manages the LTE/cellular side, the nRF5340 is like a secondary processor and the nRF7002 connected to either chip via a shared SPI bus.

Please let us know if you have any further questions.

Thanks for the detail explanation.

Hi itieledri

1 ) Yes, nRF9151 DK + nRF7002 EK is a supported combo in NCS, and also nordic Thingy91x device is using nrf9151 and nrf7002 for wifi based location.

2 ) Yes there is official sample for this like Wi-Fi: Scan sample and Wi-Fi: Shell sample , both sample you will bget in NCS, Keep ( nrf9151dk/nrf9151/ns ) board target with the ( nrf7002ek_nrf7000 )shield. build with command ( west build -p -b nrf9151dk/nrf9151/ns -- -DEXTRA_CONF_FILE=overlay-scan-only.conf -DSHIELD=nrf7002ek -DSB_CONFIG_WIFI_NRF70_SCAN_ONLY=y ).

3 ) Reference overlay examples are available in the SDK at:

sdk-nrf/boards/shields/nrf7002ek/boards/nrf9160dk_nrf9160_ns.overlay
sdk-nrf/samples/cellular/lwm2m_client/boards/nrf9160dk_with_nrf7002ek.overlay

Feature	nRF9151 DK + nRF7002 EK
Wi-Fi Scan (location)	✅ Supported
Wi-Fi Shell (scan-only)	✅ Supported
STA Mode (full Wi-Fi)	❌ Not supported
SoftAP / Wi-Fi Provisioning	❌ Not supported

4) RAM/flash gets tight running full LTE + TLS + full Wi-Fi networking + cloud together on nRF9151 (limited app-core RAM).

Nordic's own combos avoid this by running Wi-Fi in scan-only mode (CONFIG_WIFI_NRF700X_SCAN_ONLY) alongside LTE.

Full dual-stack + TLS is possible but needs trimming and checking via west build -t ram_report/rom_report.

5 ) Nordic's own Thingy:91 X validates the integrated architecture. Nordic's own reference product integrates nRF9151 + nRF7002 + nRF5340 on a single board, which implies the integrated approach is considered production-viable — at least for the Wi-Fi scan-only + LTE use case. [Thingy:91 X hardware].
