Wi-Fi Magic Packet/Wake on Wireless LAN

[Manieldyers]

I am considering using the nRF7002 for a Wi-Fi application.
I want to use an nRF54L15 as the host for an nRF7002 and operate it using Target Wake Time (TWT) to periodically check for a remote wakeup packet or poll a remote server for new data.

Currently I have another product that uses an MQTT broker that sends push notifications to the device when data is published to a topic.

My problem is the nRF54L15 may not have enough RAM for the BLE, Wi-Fi, and MQTT stacks.
I was wondering if I can use Wi-Fi magic packets then maybe I can just use the BLE and Wi-Fi stacks and not need MQTT.

Is the nRF7002 capable of waking from a Magic Packet? Is that included in the Wi-Fi stack?

Hi Daniel,

nRF54L support for running as Wi-Fi host is still on early age, you can find Limitations when building with nRF54H20 DK and nRF54L15 DK at current stage.

Both the nRF54L15 and nRF52840 have 256 KB of RAM, so you can refer to the Memory requirements for Wi-Fi applications in Station mode of nRF52840 as host, which still only support STA mode Wi-Fi stack without BLE and MQTT.

For applications using both WiFi and MQTT, the protocol stacks require quite RAM and ROM resources. In such cases, you may need to consider using the nRF5340 or nRF54H.

About the nRF7002 megic pakcet support, I did not see it mentioned anywhere in the SDK document or HW datasheet. Let me check with our developement team to get a certain answer.

I will send you one update later.

Best regards,
