Re: gnss-sdr problems
Hello Carles,
I have replaced google server with vodafone and but now front-end-cal
exists as soon as it downloads the files...
$ front-end-cal --config_file=front-end-cal.conf
Initializing... Please wait.
Logging will be done at /tmp
Use front-end-cal --log_dir=/path/to/log to change that.
