It takes a long time to obtain an IP address through multiple settings

[mrhan1992]

The software version we use on the ESP32-C6 module is esp_hosted_v5.1.1_commit_d07a9242f49. When tested in a Linux environment, it takes a long time from test_station_mode_connect to obtaining the router IP address. Generally, the time to obtain the IP is 2-3 seconds. But when setting multiple times, it will take 8-12 seconds! The test is called as follows:

    test_station_mode_connect(&m_config);
    system("dhclient ethsta0 -r -q");
    system("dhclient ethsta0 -v -nw -q");

How should we solve this problem?

We do not recognise the revision esp_hosted_v5.1.1_ But can under stand the commit d07a9242f49 - Oct 7

Issue is fixed in 54fb6dcddda49198d179e7d2985e6a9ae99d40ff Test with latest master.

Use exact same code at esp and host.

hello @mrhan1992 ,

The reason code in disconnect is 8. basically, WIFI_REASON_ASSOC_LEAVE.

Could you please test this software with some other AP or hotspot? Try to reduce the interference as much as possible from other AP/Bluetooth/Microwave oven.

If you still face this issue despite, Please enable the debug logs by running

idf.py menuconfig
choose 'Debug'

and then idf.py flash monitor

Also please collect the sniffer logs starting before connect (to capture EAPOL M1-M4 messages)

[mantriyogesh]

Also, please include both ESP and host logs from startup.

• ESP logs
  • git commit used (ESP-Hosted)
  • Include debug logs as mentioned above
  • From flashing
• Host log
  • git commit used (ESP-Hosted)
  • dmesg from bootup
• Sniffer logs
  • Run sniffer on your channel
  • Start sniffer before triggering connect

[mantriyogesh]

Can you please check if your code triggers disconnect from some leg? What happens if you comment it.

[mantriyogesh]

Can you please send us the complete logs? Please include the commands run and their output.

Also, any simple script to reproduce the issue on latest master would definitely help if we can reproduce at our end.
