[wila91]

U7_pro_20250124_163348.mp4

What happened?

Im runing WLED on ESP32 and its been running good for guite some time. Just now updated my old asus wifi to Ubiquiti U7 pro. There has been reports that there is issues whit IoT devises so this problem that im having is moastlikely something to do whit Ubiquiti U7 pro not just WLED.
So the bug it self is that when ESP32 WLED is connected to Ubiquiti U7 PRO WLED will not respond to commands at all and will say connection to light failed. it will be unresponssive for some seconds untill it will be normal for about 10s and then it will hapen again in a loop.
Also if WLED devise is connected to Ubiquiti U7 PRO all effects will stop and resume after the frize. This will loop also. Video off the problem

Any ideas what could be causing this?

To Reproduce Bug

Ubiquiti U7 PRO and ESP32 connected. Running a effect will make the problem easy to see but you will not be able to controll anything when when the device gets stuck

Expected Behavior

effect should not stop and conrolling the light should be possible

Install Method

Binary from WLED.me

What version of WLED?

Nightly Release 20250124 and WLED 0.14.0 "Hoshi" have the same issue

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

Anything else?

did some testing and its possible to ping the device but it's not possible to control

[wila91]

The video shows how at about 8 seconds the lights freeze and after a while they continue again (at about 14 seconds) and then freeze again at 25 seconds... the same thing continues. Whit my old wifi ap everything is works whitout problems

There are plenty of WiFi settings in UniFi controller regarding enabled features. Please unselect all incompatible features like fast roaming, BSSID transition, meshing, etc.

Please can you also try the _V4 bin from the nightly to see if that's any better/different please?

I have my own SSID for IoT devices. I have tried many different WiFi settings... roaming, BSSID transition, meshing are all off. There is "Enhanced IoT Connectivity" and i have tried whit that on and off. I have tried changing all possible settings that I thought might affect or help.

I have also tried their latest and few others EA fimawires (latest 7.2.22) for u7pro

Tested _V4 bin from the nightly and its the same. No change

10 seconds working 7 seconds stuck.

The speed remains the same whether there is a lot of WiFi traffic or not. Even if I turn off all other frequencies, the same thing remains. Only when I turn off the connection from the U7 Pro does the problem disappears. If I connect the WLED to my old Access Point and then its ok for the U7 Pro to be on just cant be connetion between u7pro and WLED.

Had my 3 WLEDS running chase effect at the same time and I could see them all. They were getting stuck out of sync but at the same rate. So one or two could be stuck and others were running.

[wila91]

Didn't mean to close (***phone and fat fingers)

I remember having issues on UniFi APs (WiFi5) which were resolved by fixing 2.4GHz channels on each of them and trying to get them as little overlapping as possible.

EDIT: If you haven't, check this document.

I only run one AP and the neighbors' WiFi can barely reach inside my house. I have Zigbee devices but they are ZigBee channel 11 (around wifi ch 1) and my 2.4GHz Wifi network is ch 13.

Dont know how to make it better

[blazoncek]

my 2.4GHz Wifi network is ch 13

Move away from channel 13. It is known to cause issues. Use 1, 6, or 11.

[wila91]

changed to 11. And its still the same

the channel has changed several times. It has mostly been on automatic, although now that I have tested more I have also changed manually

[wila91]

Connention should not be that bad...
And ping was good ealyer and didn't stop when leds get stuck

Ubiquiti does not like the connection

[wila91]

When the LEDs get stuck the arvage FPS shows 0

Tested _V4 bin from the nightly and its the same. No change

Can you also try a full erase and install of that env from platformIO so you also get the right bootloader please?

[wila91]

After I completely reinstalled all 3 started working normally. Shouldn't have trusted the OTA

OTA is just so easy to use whitout having to disassemble anything.

I don't understand how change of the access point made all the problems to surface.

Anyhow. Now the lights are working again!

Thanks!

I'm not 100% clear of exactly what is in the bootloader, but it does seem to do much more than just load the app

It also initialises the hardware.
