Not connecting to WiFi - Githubissues

DrmedAllel commented 3 months ago

Hardware

ESP32

Firmware version

v2.4.6

Application version

v2.4.6

What happened? What did you expect to happen?

Flashed Firmware to the ESP and done all the setup via the ESPs Wifi. After the reboot the website is not available via my local Wifi. Looked up in the monitor and realized that there is a loop while the esp tries to connect to my wifi.

How to reproduce it (step by step)

1. Flash ESP
2. Enter Wifi SSID and password
3. reboot

rstrouse commented 3 months ago

Is the passphrase correct?

DrmedAllel commented 3 months ago

Yes it is. I have tried it multiple times. Also changed the board...

rstrouse commented 3 months ago

Do you have any special characters or spaces in the SSID?

DrmedAllel commented 3 months ago

SSID is "Wi-Fi-Teck12". Sometimes I get the connection to the wifi but this is very rare. Most of the time I am stuck in the loop...

rstrouse commented 3 months ago

I don't think the dashes should be a problem. It is very odd that it looks like the router is responding with the connection but it is immediately disconnecting. It is scanning 3 APs do you have a mesh?

DrmedAllel commented 3 months ago

Yes I do. There are three repeaters and one router in my network.

rstrouse commented 3 months ago

What is odd is that it looks like it connects then immediately disconnects without serving an IP. Almost like it is bound to an AP by MAC address. If you can connect to the ESP32 WiFi AP disable Roaming and enable hidden SSIDs. Perhaps there is some band or channel steering going on for the WiFi network.

DrmedAllel commented 3 months ago

Alright, I will do so. Thank you for the suggestion. I will give you feedback once I‘ve tried.

DrmedAllel commented 3 months ago

I've tried it with disabled roaming but still wasn't to reach the web-interface after the setup process. Where can I change the setting for the hidden SSIDs?

DrmedAllel commented 3 months ago

After put in the SSID & pasword I click on "save adapter", then the logs start looking very strange:

rstrouse commented 2 months ago

That is very strange. Reboot the device by removing power then let it boot back up again.

Hi guys! Unfortunately I am facing the exact same issue. Only in rare cases the module successfully connects to my TP-Link access points mesh after startup.

Some additional information: It worked quite stable a while ago (continuously connected to WiFi for weeks) and direct WiFi re-connection on almost any startup. Now, the system crashes after a couple of hours with stack overflow issues und does not successfully reconnect:

This is why I started thinking this might be a HW issue as well. So I am doing two things now: 1) I deactivated the Roaming feature and I will observe the system for any improvement 2) I ordered some new XIAO S3 modules to check the behaviour off different modules of the same type.

I will keep you updated with my impressions. AWESOME project, by the way!

hmbacher commented 1 month ago

Hi, here the updates as promised:

1) Romaing feature does not have an effect on the issue. 2) A brand new XIAO ESP32S3 module works fine, if just connected via USB-C port but shows the same issue if mounted to the actual target PCB. 3) XIAO ESP32C3 module works perfectly, either isolated (just via USB) or integrated (put to the target PCB).

I assume it is not (only) a software issue. To identify the actual root cause, further low level analysis is required. As I am flexible in using S3 oder C3 type, I have a working and stable solution now with using the C3-module. Best regards!

theincogtion commented 1 month ago

I am using an AVM Mesh Network and I have regular problems with the connection. Most of the time it connects after start but then after some hours or days the connection gets lost. Sometimes I have to reboot several times. Please let me know if you need further details.
