OpenMarine

hello need some help to continue configuring openplotter.
I had some difficulties to upgrade opencpn to 5.8.2 version . Maybe i did wrong operation but at the end I succeded . I  also update all other openplotter applications. 
I have to configure again my connexion with serial .  The device window is OK, the connexion window is also OK, the adding to signal K is also working whereas signalK display the error message:No such file or directory, cannot open /dev/ttyOP_gnss 

Help appreciated. Thanks

What output do you get if you type this into a terminal window?

Code:

ls -ahl /dev/ | grep ttyOP

Hello, many thanks for the answer.
I get nothing  with the command line you suggested me. I did the grep only with tty and the 2 lines I get regarding the GPS are:
lrwxrwxrwx  1 root root          7 mai  18 11:48 gps-platform-3f980000.usb-usb-0:1.1.2:1.0 -> ttyACM0
crw-rw-rw-  1 root root    166,  0 mai  18 11:48 ttyACM0

I check another thing which  allow me to go forward following a signalK restart: creation of a symbolic link
sudo ln -s /dev/ttyACM0 /dev/ttyOP_gnss

thanks for your help
