TCP connection fail after TWT (Target Wake Time) being setup successfully in WIFI shell example (NCS 2.3.0 nrf\samples\wifi\shell) in nRF 7002 DK(PCA10143)

[Andrewli]

I am doing TWT setup test in in WIFI shell example (NCS 2.3.0) in nRF 7002 DK(PCA10143 0.7.3 2022.51), the router is ASUS RT-AX88U with TWT enabled.

following is my test cmd in WIFI shell  :

1. wifi scan 

2 .wifi connect Nordic_ASUS_5G  ******

3. wifi twt setup 0 0 2 2 0 1 1 1 200 1000

output:  TWT operation TWT setup with dg: 2, flow_id: 2 requested
             TWT response: TWT accept for dialog: 2 and flow: 2

4.net tcp connect 182.61.144.86 50000

output: Connecting from 192.168.50.3:0 to 182.61.144.86:50000

5. net tcp send 123567

output: Not connected

6.  wifi twt teardown 0 0 2 2

output:TWT operation TWT teardown with dg: 2, flow_id: 2 requested

7. net tcp connect 182.61.144.86 50000

output: Connecting from 192.168.50.3:0 to 182.61.144.86:50000

8. net tcp send 123567

output: Message sent

 

 182.61.144.86 is a TCP test server  in my side ,

  the issue is :  TCP send test can not work well after TWT being setup successfully  , and TCP send test work well after TWT being teardown.  my question is how to make TCP send test work well after TWT being setup successfully?

hi , TWT MQTT test updated in ASUS RT-AX88U with NCS latest main branch code :
Overview :
using samples\net\mqtt and add TWT code, :

struct net_if *iface = net_if_get_default();
struct wifi_twt_params params = { 0 };
params.operation = WIFI_TWT_SETUP;
params.negotiation_type = WIFI_TWT_INDIVIDUAL; //1st
params.setup_cmd = WIFI_TWT_SETUP_CMD_REQUEST;
params.dialog_token = 1;
params.flow_id = 0;
params.setup.responder = 1;
params.setup.trigger = 0;
params.setup.implicit = 0;
params.setup.announce = false;
params.setup.twt_wake_interval = 65000;
params.setup.twt_interval = 256000;
if (net_mgmt(NET_REQUEST_WIFI_TWT, iface, &params, sizeof(params))) {
LOG_INF("TWT setup failed");
}
else
{
LOG_INF("TWT setup success!");
}

doing TWT setup after MQTT server connected .

result: for '65000,256000' and '65000,524000' the MQTT conn is ok ,and publish and subscribe is ok.

for '65000,1000000' and the MQTT conn will disconnected after a while. why ?
