Buddy3D drops connection when printer is off

Is there any way to prevent the Buddy3D camera from dropping the connection when the printer is turned off?  I understand this is "the way it's supposed to work" but frankly it's dumb and makes many things difficult.  Since these cameras have many connection reliability issues it would be helpful when diagnosing things if the camera didn't go offline just because the printer is off.  It would also be helpful when checking the state of the printer even if it is off.  If the limitation is due to PrusaConnect capacity then stop uploading the 10s snapshots when the printer is off but do not block the ability to manually use "Take Snapshot" or Pan&Tilt features.  

Other than frequent connectivity issue this is the biggest problem with Buddy3D.  Please consider addressing this.

Are you powering the camera separately from the printer?
What are you using to view the camera? If it's separately powered, you should be able to view the RTSP stream.  Yes, it's dumb that Connect stops showing the camera when the printer is off even if the B3D is powered on.  I assume that's what you're asking for.

Yes, my Buddy 3D is powered separately from the printer so it is always powered. It becomes inactive when the printer is off and (dumbly) connect won't show the camera feed unless I go turn the printer on. Even then it does not become available without power-cycling the camera. For me camera functionality within Connect is entirely broken. Does Prusa even use these cameras themselves. Seems unlikely given how flakey they are.

There's another thread on this, but if you haven't seen it, this appears to be an issue with 3.1.2

I can run 3.1.1 fine, but the camera forgets the connection on reboot under 3.1.2

Amazingly, the fix is to ensure that your WiFi password is made of a multiple of 8 characters. So mine was 15, but when I changed it to 16 it cured it!

Hopefully there'll be an update soon, but this does work!

John, Thanks for the info.  I wish this camera was better supported.  The only ones seriously looking into these problems seems to be the commenters in the forums.
