Packet size is not more than 70 bytes in Monitor sample

[HarryAc]

Hello,

Using wifi monitor sample on NRF7002 DK, packet length is constantly 70. It was checked both by reading received variable from:

received = recv(packet->recv_sock, packet->recv_buffer,

sizeof(packet->recv_buffer), 0);

And by using NET CAPTURE feature in Wireshark. The last received tag is Supported rates.

Using typical Realtek Wi-Fi adapter I have monitored traffic and same packets are way bigger and contained more information.

What might be the problem?

Regards,

Hi,

 

There is a bug in the wifi monitor sample that limits to 70 bytes (minus 6 bytes of header) - there's a workaround that is posted in this thread:

 NRF7002 Monitor mode issues 

Could you try that?

 

PS: There is a limit of 255 bytes at this time, as described in the comments in this thread:  nRF7002 Linux driver with Monitor Mode 

 

Kind regards,

Håkon
