nRF7002 can detect and act on any unicast packet addressed to it but does not have a specific filter for "magic packet".

Hi Charlie, I'm not sure I understand. Is the developer saying that the nRF7002 can handle any unicast packet, but does not have a specific filter for a "magic packet"? Or is the developer saying that the nRF7002 cannot handle unicast packets at all?

Here is the reply from developer.

Yes nRF7002 is capable of waking the host processor, but not via any Magic Packet, rather any Wi-Fi unicast pkt. The filtering for a Magic Packet is not present, but can be added as a feature enhancement.

Best regards,

Charlie

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,

Charlie
