Run throughput test using iperf2 TCP on nrf7002 DK

[thp2023]

I am attempting to run a throughput test using TCP on the nrf7002 DK as the client and my laptop as the iperf2 server. I am using the sr_coex sample listed in sdk-nrf repo, and modified the following files: src/main.c and prj.conf. In prj.conf I modified the following parameters:

CONFIG_STA_KEY_MGMT_WPA2
CONFIG_STA_SAMPLE_SSID
CONFIG_STA_SAMPLE_PASSWORD
CONFIG_WIFI_ZPERF_PROT_UDP
CONFIG_NET_CONFIG_PEER_IPV4_ADDR

I set CONFIG_WIFI_ZPERF_PROT_UDP to y and the others with my Wifi credentials. I can confirm the Wifi credentials are correct since I was able to perform the throughput test with UDP with no errors.

In the src/main.c file: I changed the following

udp_callback to tcp_callback in line 63,

udp_upload_results_cb to tcp_upload_results_cb in line 303,

udp_callback to tcp_callback in line 332

zperf_udp_upload_async with zperf_tcp_upload_async in line 464

udp_callback to tcp_callback in line 480

After I saved my changes, I used the following commands to build/flash my nrf7002 DK board

west build --pristine  -s <path/to/app> -b nrf7002dk_nrf5340_cpuapp -- -DCONFIG_MPSL_CX=n -Dhci_rpmsg_CONFIG_MPSL_CX=n

west flash --dev-id <DEV_ID>  --hex-file build/zephyr/merged_domains.hex

Both build and flash was successful, I see the throughput test can run, but in the logs I get several messages that look like the following:

<wrn> net_conn: conn_raw_socket: pkt cloning failed, pkt 0x20052cc8 dropped

My question is if there's something else that I need to do to stop getting that error message in order to run a throughput test using TCP

Hi,

I set CONFIG_WIFI_ZPERF_PROT_UDP to y

You must set CONFIG_WIFI_ZPERF_PROT_UDP=n to use TCP.

What command are you using to run iPerf? For TCP you must use the following:

iperf -s -i 1

Best regards,
Marte

Thank you for replying. I miswrote the question. I did set CONFIG_WIFI_ZPERF_PROT_UDP to n. The command I used to run iperf I did the following:

iperf -s -i 1 -P 1

I added the -P flag since I only want iperf to run for one client and exit. When I ran the test and check the logs, I noticed the iperf test starts, but the logs display several of the same messages during the test run:

<wrn> net_conn: conn_raw_socket: pkt cloning failed, pkt 0x20052cc8 dropped

Hi,

Since packet cloning fails, you are most likely running out of packet buffers. This means there is a buffer leak somewhere.

Can you enable Zephyr's network shell so you can observe the buffers?

In prj.conf set the following:

CONFIG_SHELL=y
CONFIG_NET_SHELL=y
CONFIG_NET_BUF_POOL_USAGE=y
CONFIG_NET_DEBUG_NET_PKT_ALLOC=y

Then you can use the commands net mem and net alloc to see information about network memory usage and allocations.

Can you share the full log from the device?

Best regards,
Marte

Hi,

You need to increase the TX and RX buffers.

CONFIG_NET_PKT_RX_COUNT=32
CONFIG_NET_PKT_TX_COUNT=32
CONFIG_NET_BUF_RX_COUNT=32
CONFIG_NET_BUF_TX_COUNT=64

This should solve the packet dropped issue.

Best regards,
Marte
