RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
I noticed that the camera I have, and the replacement I was sent has a 'Hardware version' of NB.1.1.0 (screen grab attached). Can I ask please if anyone else here can have a look at the camera in their Connect app (when the camera's connected) and see if their Hardware version is the same? I may be barking up the wrong tree, but I wonder if the firmware update is only having an issue with some hardware versions? It doesn't make sense that everyone isn't complaining about this, but there is clearly something wrong.
I've checked the hardware revision of my camera, and it is also NB.1.1.0 and it is using firmware 3.1.2.
My Wifi is unifi based, using their IoT specific 2.4ghz wifi SSID. In my case, it is a hidden network and I have enabled Client Device Isolation. The Core One printer is connected to my original IoT network, the only difference being that the SSID has a space in it.
I've tested the camera several times now by powering the printer off and on, and the camera reconnects every time.
Eight character password IS THE FIX
In addition to the above, and having read through the comments here, I tried changing my WiFi password to being a multiple of eight characters (it's 16 now, and was 15). I then updated via the app and the camera is now stable and reconnects after a reboot.
I'll let the person I;ve been talking to at Prusa know, but it does seem a bit strange that they're not all aware of this problem and the 'fix'.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
The password for my IoT SSIDs are 15 characters. The password is the same for both working and non-working SSIDs. The only difference between working and non-working SSID is a space character in my particular case.
SSID with reconnection failure: 12 chars (with space)
SSID that works: 11 chars (no space).
Same 15 char password for both.
Both hidden networks, but I still had reconnection failures when I made the non-working SSID visible as a test.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Based on my experience, change the password to 16 characters and your problem will be solved.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
As a test, I created a new IoT wifi network, same settings as the others almost identical to the first one with a space in the SSID (I kept the SSID the same number of characters), but I used a 16 character password - essentially just adding another character on to the existing password - and the testing was successful!
"Weyland Labs", "XenoLivesMatter": Reconnection failed.
"Testand Labs", "XenoLivesMatter1": Reconnection successful.
"WeylandLabs","XenoLivesMatter": Reconnection successful.
I figured it might be useful to post the SSIDs and passwords I tested with. These are hidden networks and chances of anybody figuring out where exactly in the world I am are very slim. :p
I'm happy to test other SSID/password combo scenarios if anybody wants, as it's easy enough to do with my setup.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Sorry.., missed your earlier post that you have it working with 15 characters! It certainly cured mine, but good to know you're sorted
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
I have NB1.0.1
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Changing the password is a non-starter for me, i would then have to touch many devices to update the password.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
I have NB1.0.1
Definitely 1.0.1, not 1.1.0? That sounds like it's older than the one I have
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Not sure if this will help anyone but I was facing the same issue - 3.1.2 always failed to connect to WiFi after printer PSU power cycle (3.1.1 was fine for quite some time before the update).
I had neither of special characters that were mentioned here or on chat with Prusa.
Both, SSID and password are on the longer side (SSID 10 characters and password 20 characters) both with upper and lower case letters, numbers and multiple special characters.
What I did the day it started working properly:
1. Created new SSID with just upper and lower case letters (no special characters, numers or spaces) of the same length as the "problematic one" .
2. Reset the camera
3. Paired via mobile app using new WiFi details QR code
4. let it run for a moment
5. pulled the cable from camera (had a print going at that time so couldn't power down the printer)
6. waited a few minutes
7. plugged the cable back in
8. camera reconnected to WiFi just fine
I did the same once again using the original "problematic" SSID & password and it also successfully reconnected after plugging the USBC cable back into the camera.
Not sure if it's relevant, but I noticed the camera powered down easily noticeable few seconds after I pulled the USBC cable from it (probably some capacitor keeping a bit of charge) compared to instantenious camera led flash stopping after powering down via printer PSU.
Just wild speculations, but maybe there is some issue the way camera powers down after initial pairing, where it drains quicker when connected to the printer? Power cycle via unplugging cable from camera itself allowed it to "save" config properly and thus properly connect back to saved WiFi?
This worked for me.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
My connection kept disconnecting, and I solved it as others have mentioned here, by changing the password for the 2.4G Wifi network to a 16-character key (uppercase and lowercase letters and numbers without spaces).
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Has anyone gotten info from Prusa about a firmware update or fixes for thee wifi issues?
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
IDK about any of that. But I'm about to flash my camera to an older firmware for the FOURTH time.
One
Two
Three
Four
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Thanks for all the suggestions, my BuddyCam is connected now and working fine, after power off/on also. Hopefully it stays that way. I implemented firmware 3.1.1, changed wifi password to 16 digits, disabled 5 ghz.
RE:
So... it seems update 3.1.3 solved the problem! Now camera connects to wifi after turning the printer on. 🙂 On the other hand - RTSP ceased to work. But that's maybe because 3.1.3 is not full release (?).
EDIT: RTSP was turned off after the update, it seems it works somehow (but at least my Home Assistant has problems with the stream now, it worked well before).
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Where did you get firmware 3.13? download location?
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
On the same place as the 3.1.0. Read this post on Reddit, then you can download & update the camera manually.
https://www.reddit.com/r/prusa3d/s/Gp2AjytqWN
But I think 3.1.3 is not a full release yet? So be aware of it. Anyway, it works for me including the new live stream function.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
I just did some checking after hearing about 3.1.3.
3.1.2 is still being pushed. https://connect-ota.prusa3d.com/
Changelog says 3.1.3 was done. https://prusaconnect.sleekplan.app/changelog
I modified the URL for 3.1.1 and you can grab 3.1.3. I assume the same "rename to cus_update_ota.tar and boot from card" works. I'm in the middle of a print, can't try it. connect-ota.prusa3d.com/file/cam-3.1.3.tar
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Wow! Thanks for the tip, I had already given up hope.
I updated (SD-Card) to version 3.1.3 and it works. Long SSID and password with spaces and special characters are accepted. Now I can finally switch off the subrouter with its separately configured VPN. One less energy consumer.
RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2
Yep, the manual way (renaming the file) worked for me.
