CORE One L Buddy cam always reports “WiFi connection failed” after reboot  

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

I'm having issues as well.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

I just spent some time online with support - I sent them video of the camera always announcing “WiFi connection failed”. Re-pairing using the QR code works, so the WiFi works. But it does not survive a reboot 🙁

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

The same with me. Adding microSD didn't help (it was recommended in an other post). Wonder if it's my wifi/firewall restrictions or camera itself.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

I had a similar issue and needed to reset the camera via the button on the side, then it seemed to connect.

I had a similar issue and needed to reset the camera via the button on the side, then it seemed to connect.

I was asked to perform a Factory Reset (hold the reset for approx. 20s, the camera will announce that it is performing a Factory Reset). Unfortunately, it still does not remember the WiFi for some reason, so after every reboot the camera still reports "WiFi Connection Failed". The camera cannot be used with this issue.

Note that initial pairing using the QR works just fine, so there is no issue with either SSID, WiFi password or signal strength. I even tested this with a different WiFi.

So: this could be a hardware issue or a firmware issue; Prusa Support is still working on it.

RE:

Same issue here (Core One buddy cam), I need to re-pair using the qr code to get it online again after it has been shut down (this time because of fw update of printer).

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

Hey, have the same issue.

Updated my three cameras and now they forget the wifi password after each power off.... 

Please fix Prusa!

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

I had a similar issue but with a much longer password (63 chars). After I changed my password to 57 chars, it started to work (50 chars worked as well, so I tried removing one char at a time to figure out the max). In all cases, they were exclusively alphanumeric.

Yours is apparently much shorter, so I have no idea if it could be related, but maybe try changing your password to a different size ? (Not quite sure what black magic would make 31 fails but 50 or 57 chars works but…)

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

Hey, I fixed the issue by downgrading again to 3.1.

See this article for a HowTo: https://www.reddit.com/r/prusa3d/comments/1lproh0/update_do_not_buy_the_buddy_camera_3d_for_core/?tl=de

in short > download https://connect-ota.prusa3d.com/file/cam-3.1.0.tar

rename to cus_update_ota.tar

copy on sd card (Fat32)

camera off > insert sd > camera on > wait until done.

register camera to printer

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

Thank you! I will try this immediately

I wish Prusa Support would at least have acknowledged this firmware regression, and pointed me to this downgrade option…

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

The camera immediately auto-upgraded to 3.1.2 so no joy 😉

I wish there were a “pin” option to prevent auto-upgrades.

RE:

I had the exact same issue for about 1 hour of testing and debugging. Never found out what is the issue, but this is what i did before it got fixed:

1. updated to 3.1.2
2. Connected the camera to wi-fi
3. Rebooted the whole printer (from power cable)
4. Removed the camera from Prusa connect
5. Reconnected the printer to wi-fi
6. Added the camera again, and connected it to wi-fi
7. Rebooted the printer from power cable again. 

It works now for the last 4 days, and after at least 6 reboots. 
I have tested a bunch of other things before that, but that was the last steps that I remember before it worked.
Hope it helps.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

+1 seeing this on my Core One on Unifi home network. 

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

If Prusa Engineering is reading this forum: my setup is also Unifi, 2.4GHz and 5GHz bands enabled; “WiFi 5”.

Unfortunately I haven’t heard from Prusa regarding this specific issue for a couple of weeks now (the email issue-tracking has room for improvement).

Since the BuddyCam is  currently useless with no fix 0n the horizon, I will try and build an ESPcam instead.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

Hi,  Same problem here.  Prusa core one with camera.

Tried a few times yesterday and will not reconnect after power cycle.  Camera works ok after using the QR code and will show images in the app, but after cycling power it fails to re-connect. 

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

Mine came with 3.1, no problems. I would place 3.1 on a SD card and downgrade per @TPdesign. Not sure how Ed's camera auto updated itself as there is no option to do that, there is a very easy to tap link in the app, stay away from it.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

I think the camera auto-updates to 3.1.2 via the WiFi internet connection, so no joy unfortunately.

RE: CORE One L Buddy cam always reports “WiFi connection failed” after reboot

My camera is connected to Wifi and has not updated. Did you wipe the SD card, after it went to 3.1.2 the 1st time, if it downloaded it to the SD card, then it will keep happening. I am also not using an SD card, that may be part of it.

I downgraded camera to 3.1.0 and it stays on this level (even though in the app I see a flash icon with possibility to update). And it works perfectly now. I was also able integrate it to Home Assistant, which is great, because you can integrate the RSTP stream, so I see live video from my mobile from everywhere, not only from my home network. Better than the 10 sec. updates in Prusa Connect app. Now I am satisfied with the camera. But I would welcome new stable update. I am bit worried it will break something else, though. 😀
