Hello I am trying to connect a GPS Usb Glonass Ublox7 with nmea_serial_driver and I can't. I have checked where it is connected using ls / dev / tty * and I have it connected in ttyACM1.

If I run the command: $ sudo cat /dev/ttyACM1 or $ sudo cat /dev/gps1

I get NMEA sentence. However when executing the command:

$ rosrun nmea_serial_driver _port:/dev/ttyACM1 _baud:=115200

I get the following error that can't open port

The Glonass GPS supports any standard baud rate.

If I run the following command: $ groups <myusername>

I get the following: <myusername>: lauratfg adm dialout fax cdrom floppy tape sudo audio dip video plugdev input nopasswdlogin lpadmin scanner gpio i2c spi sambashare samba

I don't know what else to do ... Help please. This gps doesn't work with nmea_serial_driver?

Thank you. Greetings.

The problem was that I had the gpsd daemon installed. The solution has been to find which process was using the port for this I opened a terminal with the following command: $ ps aux After this, all the processes appear in the terminal. I looked for the one called gpsd which had a number assigned for example 3223. I opened another terminal and ran the following command: $ sudo kill -9 3223 From here, I was able to run the node nmea_serial_driver. I also recommend disabling bluetooth
