I recently tested several cameras on all of the RPi usb ports. Now, when I’m setting up the cameras in the BlueOS menu, there is a mess of “connections already in use” and the IP:port numbers are confabulated as well.
Is there a simple way to reset the RPi to remove all the erroneous, previous connections?
I’m hoping that just re-flashing the entire system is not necessary.
Happy New Year!
Hi @oceanq -
You should be able to remove any unwanted entries on the Video Streams page simply by deleting them (red trash-can icon)? Can you share screenshots of the “mess”?
Note that fewer entries will appear if you are not in Pirate Mode…
I tried using the trash can icon, but it doesn’t help.
I’ll try to get screenshots on Monday.
It seems like the issue is in the way the RPi handles /dev/video being connected to the physical usb port.
It seems there is a log file somewhere that records the serial number of the USB device and BlueOS is not able to completely remove the discarded entries.
I see this as similar to, when using an USB-serial adapter, the com port can be assigned a new number (eg from com 10 to com 5), but sometimes it alerts the user that “com port is already in use”, but the user can override/force the change.
In windows you can delete the com port registry, and it refreshes the number scheme that the OS uses, each time a device is plugged into the usb. (See ftdi example instructions below)
I’m forever rusty with RPi OS, since I don’t get to tinker as much as I want.
PS, I’m using the H264 low light cameras from BR.
Have a great weekend!
