[BUG] WLAN connection breaks off after a while #254

Closed pr1m300 closed 1 year ago

pr1m300 commented 1 year ago

Bug report

Describe the bug

After several hours, there is suddenly no connection to the WiFi and no current data from my custom apps are displayed, Awtrix's own apps continue to work. The apps also continue to scroll normally and also display data.

After I restart the display, it works again for a few hours. In the meantime I have already reduced the custom apps to only 4. I transmit the data via MQTT every 30 seconds.

Additional information

To Reproduce

Steps to reproduce the behavior: I just have to wait long enough

Thanks

possible dublicate of https://github.com/Blueforcer/awtrix-light/issues/197

pr1m300 commented 1 year ago

Thank you for the link to the other thread.

I also have a UniFi system and have switched off the automatic channel search accordingly.

Unfortunately the problem persists, what could it be? I would be very grateful for any help or a thought-provoking impulse.

RDG88 commented 1 year ago

I had this issue also when my AP was on channel 11, i have Unifi's also. Try to change the channel for 2.4ghz to 1 or 6.

hytrek commented 1 year ago

Same issue with me. Using Unifi as well.

Suggestion: force fw. of watch to re-try connecting to wifi when signal is lost. When signal is lost restart always helps for some undefined time.

changed channel to 1 but wonder if that provide other conflicts... I have 7 AccessPoints and before that change they were all set to nightly channel optimiozation...

robercy commented 1 year ago

I possible fix, will be a watchdog: on wifi.disconect() start timer, if disconnected more than X minutes, then esp.restart().

Blueforcer commented 1 year ago

Please read linked issue #197. It's look like a hardware or Framework issue. Wifi reconnect is already enabled https://github.com/Blueforcer/awtrix-light/blob/a96ce12366584bc1b423093d2206654754052252/lib/webserver/esp-fs-webserver.cpp#L172

Restarting the ESP will cause another issue to be opened ...

robercy commented 1 year ago

Thanks again. I read the issue #197, and the solution works indeed, but in few cases, didn't work. I agree with you, restarting can cause more trouble than help. I will look my setup, to find the problem. I just try to help. Keep the great awtrix rolling.

Thanks again. I read the issue #197, and the solution works indeed, but in few cases, didn't work.

I ran into the same problem - also with Unifi hardware. I looked at the mentioned issue as well and completely disabled the "Channel Optimization". However, the problem persists - after a few hours (sometimes more, sometimes less) the wifi connection is lost again.

Same issues kept me busy the last to days. Everyting was fine on 0.71 and problems started with 0.72.

I could find a way around, now all is working stable again.

The issue seems not to be related to the FW itself but rather through the way of flashing it.

I flashed 0.72 over 0.71 using the integraded update function.

Once I flashed the FW over the webinterface things worked again as expected.

TJHooker commented 1 year ago

seems this happens also with AVM WLAN Router if ichange settings for example MAC Filter the router makes short WLAN disconect and the Ulanzi is not able to Connect. Only if i Push left+right botton for power off and on wlan reconnects

robercy commented 1 year ago

Kudos to @GitHoubi ! I follow his guide, and wifi do not disconnect since applied. Seems to be a flashing memory allocation problem.

GitHoubi commented 1 year ago

I know it somewhat does not make sense since the FW certainly is exactly the same...

But everything seems to run more stable if flashed via Web UI instead of the button press update.

I tried so many times. 0.71, 0.72, 0.73 all of them get instable after a while when flashed via device directly.

robercy commented 1 year ago

Thats right, @GitHoubi . Like said a old man friend of mine: There is more mystery inside a cpu/mcu than our vain philosophy dreams of. Thanks by your tips.

with webinterface you mean the Awtrix light frontend and then the Update tab? Or do you mean connecting the device via usb cable to computer and then use the flasher (https://blueforcer.github.io/awtrix-light/#/flasher)?

correct, AWtrix light Frontend and the update tab. This seems to work fine, so does the WebFlasher on https://blueforcer.github.io/awtrix-light/#/flasher via USB. But the update function within the device itself (OTA style), this seems to be part of the problem.

bimbolongo commented 1 year ago

Unfortunately, none of the suggestions have worked for me so far.

What I've already tried.

Delete and flash again

Update from 0.71 to 0.72 or 0.73 via the web interface and with the online flasher.

Only a downgrade to 0.71 solves the problem and everything works again.

I am using a custom build with an ESP32 (ESP32 NodeMCU Module WLAN WiFi Dev Kit C)

If anyone has any suggestions to solve the problem I would be happy.

davlaw commented 1 year ago

Maybe use tasmota method of using conx to mqtt? If that fails reboot?

robercy commented 1 year ago

In my projects, I use a state machine to keep wifi and/or mqtt alive.

pr1m300 commented 1 year ago

Ich hatte dieses Problem auch, als mein AP auf Kanal 11 war, ich habe auch Unifis. Versuchen Sie, den Kanal für 2,4 GHz auf 1 oder 6 zu ändern.

For a few days now I have set all APs to channel 1. Since then I have had no more disconnections. Has been running for a little over 3 days now. thanks for the tip

interessting ... i had set my AP to channel 6 and i had disconnections. I've now changed it to channel 1 and "locked" my pixel clock to the AP near the clock. Maybe this will help ...

Hmmm this got me thinking. I configured my clock in my office. There it probably connected to my AP that's right there. Then I moved my clock to the living room. There I had once the issue that the clock lost connection after a while. Maybe because it switched to another AP in the living room. Since then I didn't have the issue anymore. Running fine now for 4 days.

hytrek commented 1 year ago

Same here - using Unifi aswell- after changing all my APs to channel 1 the clock stays online stable since 5 days. As I am not an expert for Wifi I have no clue weather this has some effects on other devices or the general performance.

Blueforcer commented 1 year ago

seems like to be an hardware/framework issue after all of your reports. So im closing here, unfortunally nothing i can do here.
