I can also observe the esp32s3 abnormal if I change AP from "20/40MHz" to "20MHz" and then switch back to "20/40MHz". below shows the "Disconnect reason: 34" log |
|
I can reproduce only when the AP's RSSI is -5X ~ -7X. |

Hi @AxelLin
This means AP can not receive S3 reply 802.11 acks, also from below comments:
seems this issue related with S3 tx power is abnormal. Could you please upload the sdkconfig?
Or:
Thanks. |

Hi @MaxwellAlan I have much less chance to see "Disconnect reason: 34" after setting CONFIG_ESP_PHY_CALIBRATION_AND_DATA_STORAGE=n, However, it may take quite long time to upload a 40KB file (sometimes it took 20 ~ 50 sec), the AP RSSI is -67. But the ESP32 test is stable and just needs less than 5 sec when test at the same place. Below is the long when I got disconnect reason 34, (just once). |

Hi @AxelLin
seems PHY recalibration can make TX power to normal, but there still have some issues, maybe related with Bandwidth, did you test with AP bandwidth HT20-only and HT40-only to check whether HT40 issue. |
|
We have observed several wifi issue with S3, but not every device is debug build. Also it looks like using esp_camera has impact on wifi transfer. |
|
BTW, is there any API I can use to check if TX power is good or not? |
|
I notice ESP32S3 may switch channel multiple times when join an AP. Below is ESP32 log for comparison: |
|
I also observed below symptom when test with freenove s3 dev board:
ping the device: |

hi @AxelLin |

@hansw123 The AP mac: ac:15:a2:4e:6b:47 |

@hansw123 According to this comment https://www.esp32.com/viewtopic.php?f=2&t=40111&sid=283a77286dd295dcfdd896e2c0d6e3f2#p133443 , the impact of usb is very limited. |

As I said in prvious comment, your colleague says the impact of USB is limited. I (2345) net_utils: Joining AP: IGS-MESH I (5247) wifi:dp: 1, bi: 102400, li: 3, scale listen interval from 307200 us to 307200 us I (16043) wifi:idx:1, tid:0 Could you help to check if this is related to esp_camera usage? (This happens after lcd_camera_controller is enabled) |
|
Attached 2 wireshark log that uploading data to http server: 1 ok case, 1 fail case. |

If the cam_task task priority is a concern, you should talk to the esp32-cam maintainer @me-no-dev BTW, I tried lower cam_task priority by modifying esp32-cam code, which seems not related to this issue. |

The interference between CPU, camera and antenna seems to be a common issue on esp32/esp32s3 as it has been reported by several users. see It would be helpful if espressif can provide some s/w and h/w design guideline |

In addition to these, I tried to run the station example. Except that Bluetooth and the LVGL&RGB screen are completely disabled, other conditions are the same, and the example can successfully connect to the AP. I hope the above information can help you locate the problem. |

I tried to reorder of WiFi configuration calls, and it worked. The following is the current call order:

I have the same problem in IDFv5.1 with ESP32S3. esp32s3 takes time to connect to the internet while esp32 doesn't have this issue |

What is the expected behavior?
Join AP should work.
What is the actual behavior?
Test with tp-link AX1800 AP, security: WPS2-PSK[AES].
When the AP 2.4G setting is "20/40MHz" with channel "auto", it was working fine.
However, after I switch channel "auto" to channel 1, the esp32s3 behavior abnormal.
ps. I also test esp32 and esp32 does not has such issue.
Below show the log to join AP , it keep retry if got disconnect, but always failure.
Steps to reproduce.
Just make device join the AP.
Debug Logs.
More Information.
Seems keep receiving Disconnect reason: 34
