Hi there. I have a bluetooth GPS device, called "BT GPS"..
I'm using KDE and its applet sees the device, marked as Trusted and has a green checkmark next to it.. It also says Uncategorized for it.
When I right click over it and select Connect->Serial port, it gives me an error,saying Connection Failed: Failed to get rfcomm channel

I added my user to lots of groups that might be related. didn't help. I installed gpsd and gpsd-clients and enabled/started it..

Any ideas how to get it to work? I'm trying to get OpenCPN to work with it basically..

PS: I saw this in the journalctl -f :

Here is another attempt:
