Hi,

[quote user="Nop Microwave"]Any solution to be sure not to drop any packets in congested uses case ?[/quote]

We currently do not offer any wifi monitor mode that can handle such a throughput, unfortunately.

Kind regards,

Håkon

Hi,

You can setup the nRF7002 in monitor mode, as described in this sample:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/monitor/README.html

However, please note that the overall throughput is highly limited by the nrf7002 capabilities, and the host controller (in this case the nRF5340) transport speed:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/monitor/README.html#offline_net_capture

The throughput of the nRF5340 USB is around 300 kByte/s, which will make the interface drop packets in congested use-cases.

Kind regards,

Håkon
