Thanks for the tutorial @Pat, it works like a charm.
I have two things to add :
-
The COM port you indicated may not be the same for someone else (if the module isn’t plugged in the right USB or if the Raspberry Pi is a different one, for example). Thus, to find out which COM port to use, one should follow this procedure :
a) Leave the module unplugged and run this command :dmesg | grep tty
b) Plug the GNSS module in any USB
c) Run the command again
d) Look for the line that was added to the command’s answer. For example, on my setup, the COM port ttyACM0 was added (the same as for Pat, but this may not be the case for you) :
-
If one has special characters in its PASSWORD or MOUNTPOINT, single quotes can be added at the beginning and the end of the string. For example, this would give :
@reboot /home/pi/RTKLIB-rtklib_2.4.3/app/str2str/gcc/str2str -in serial://ttyACM0:115200:8:n:1:off -out 'ntrips://:PASSWORD@rtk2go.com:2101/MOUNTPOINT' &
If one has a single quote in its PASSWORD or MOUNTPOINT, the string can be closed just before, the single quote is then escaped with a \ and the string is then reopened with another single quote. More details here : shell - Which characters need to be escaped when using Bash? - Stack Overflow
@Francois your auto-restart feature after a str2str crash interests me a lot as it can enhance the overall system reliability. I found your post (RpiNtripBase - #6 by Francois), but I don’t get how your command works. It doesn’t work when I add it to crontab with crontab -e. Can you give more details please ?
