General issue report

Hi team,
sorry for posting this on github issues instead of forum, but its important in my project.

We have 802.11 beaconing which is sending CCX, IBSS and WDS packets on different channels, but wireshark can catch packets only on channel 1 and im not sure if its issue with wireshark or esp32.

Logic:

• run wifi in STA mode
• not associated with any STA
• TX on channels 1, 6, 11

esp-idf 5.3 and master

Thanks

@chegewara
Are you calling esp_wifi_set_channel() and then calling esp_wifi_80211_tx() ?

[chegewara]

Hi,
yes, thats exactly what i do.

    ESP_ERROR_CHECK_WITHOUT_ABORT(esp_wifi_set_channel(channel, WIFI_SECOND_CHAN_NONE));
    auto err = esp_wifi_80211_tx(ifx, buffer, len, en_sys_seq);
    ESP_ERROR_CHECK_WITHOUT_ABORT(err);

Thanks

PS i just want to confirm with espressif its working as expected, since my wireshark cant catch packets on channels other than 1

Are you using ESP32?

[chegewara]

Yes, its esp32 pico V2

Hi, I just test on the master branch, using the station example, on ESP32. When the channel change to 6/11, I can capture the packets on channel 6/11.

Thank you for confirming this.
Have a nice weekend.
