5. clone the repository in /home/ubuntu

6. Validate and modify the setting for the serial port and baudrate in the autolaunch.sh nano /home/ubuntu/SonarSimulator/autolaunch.sh python /home/ubuntu/SonarSimulator/Script/sonar_simulator_DPT.py /dev/ttyUSB0 9600 the 2 last argument are the serial port and the baudrate ex: python /home/ubuntu/SonarSimulator/Script/sonar_simulator_DPT.py /dev/ttyUSB1 9600 python /home/ubuntu/SonarSimulator/Script/sonar_simulator_DPT.py /dev/ttyAMA0 115200

7. go in the install directory and run the installation script cd /home/ubuntu/SonarSimulator/Install ./install.sh

The script is installed as a service. If you do some modification in the autolaunch.sh file you have to relaunch the service. sudo systemctl restart nmea

to show the status of the service : sudo systemctl status nmea to start the service : sudo systemctl start nmea to stop the service : sudo systemctl stop nmea
