Aftertrying to work ofline with the GPS antenna (ublox-8), the ntp.service is not working (failed) and I cannot acces to the ntpq -p when I wnat to see the if SHM() is getting information (ntpq: read: Connection refused). All the other service are working properly and active (gpsd.socket, gpsd.service and ntp.service).
I am just doing some testing to install the RS outside in stand alone mode (I already put it in that mode, rsh-stand-alone: STAND-ALONE Mode is ON).We bought the RS in 2017 aprox, but I burn a new SD card with the last firmware in a 32 GB card.
The name of the antena is “ttyACM0”.when I use gpsmon it shows all the information in real time of the GPS, but when I use cat /dev/ttyACM0 show me an error (cat: /dev/ttyACM0: Device or resource busy).
The gpsd-mgr log file repeat mainly this error: “Required output from command ‘cat /dev/ttyUSB[0-9]’ not found, please investigate.”
