User not in dialout group can't access tty* #88

Closed Stefal closed 10 months ago

In these cases, str2str can't acces the gnss receiver

We should check the group ownership and add dialout if needed.

The way we check dialout group membership doesn't work. The test is a success in all cases, but:

stephane@rtkbase-test:~$ sudo groups stephane
stephane : stephane dialout cdrom floppy sudo audio dip video plugdev netdev bluetooth
stephane@rtkbase-test:~$ groups stephane
stephane : stephane dialout cdrom floppy sudo audio dip video plugdev netdev bluetooth
stephane@rtkbase-test:~$ groups
stephane cdrom floppy sudo audio dip video plugdev netdev bluetooth

See the last groups command. And in this case (user not a dialout member before the RTKBase installation), str2str_tcp can't acces /dev/tty* and the script doesn't warn the end user that he must reboot.

My mistake, the gnss receiver was not connected during the installation, so the tty was a wrong one.
