Hi,
I wrote these codes on terminal and uploads completed. But I dont know how can I connect Navio2 to Qgroundcontrol for Ardusub. As you know there are 3 options: ardurover, arducopter and arduplane. I mean when I write sudo emlidtool ardupilot i only see these options. How can I compile Ardusub?
I am waiting for your helps. And sorry for my English.
Hello,
First I’m not ardusub user (arducopter with Navio2) but the ground is common.
Ardusub usage is not integrated in EmlidTool. So I will guide you with some alteration to the Navio2 wiki. I will not use your compiled ardusub file but the latest stable…
Arduxxxx executables are stored in /opt/ardupilot/navio2
pi@navio:~ $ cd /opt/ardupilot/navio2
There are directories for common vehicles:
pi@navio:/opt/ardupilot/navio2 $ ls -l
total 16
drwxrwxr-x 3 root root 4096 Sep 22 2017 arducopter-3.5
drwxrwxr-x 3 root root 4096 Sep 22 2017 arduplane-3.8
drwxrwxr-x 3 root root 4096 Sep 22 2017 ardurover-3.2
drwxr-xr-x 3 root root 4096 Aug 25 07:04 ardurover-3.3
I will create a new one for ardusub
pi@navio:/opt/ardupilot/navio2 $ sudo mkdir ardusub
and verify it is OK:
pi@navio:/opt/ardupilot/navio2 $ ls -l
total 20
drwxrwxr-x 3 root root 4096 Sep 22 2017 arducopter-3.5
drwxrwxr-x 3 root root 4096 Sep 22 2017 arduplane-3.8
drwxrwxr-x 3 root root 4096 Sep 22 2017 ardurover-3.2
drwxr-xr-x 3 root root 4096 Aug 25 07:04 ardurover-3.3
drwxr-xr-x 2 root root 4096 Aug 25 07:22 ardusub
Then open the ardusub directory
pi@navio:/opt/ardupilot/navio2 $ cd ardusub
I will install the latest stable of ardusub from ArduPilot firmware : /Sub/stable/navio2
pi@navio:/opt/ardupilot/navio2/ardusub $ sudo wget http://firmware.ardupilot.org/Sub/stable/navio2/ardusub

pi@navio:/opt/ardupilot/navio2/ardusub $ sudo chmod +x ardusub
Done…
Now there are some files to edit and actions to do…
First ardupilot service to instruct where to find the ardusub executable:
pi@navio:/opt/ardupilot/navio2/ardusub $ cd
pi@navio:~ $ sudo nano /etc/systemd/system/ardupilot.service

Then we need to configure the communication parameters. Replace my PC IP by yours for UDP connection:
pi@navio:~ $ sudo nano /etc/default/ardupilot
#Default settings for ArduPilot for Linux.
#The file is sourced by systemd from ardupilot.service
TELEM1=“-A udp:192.168.1.20:14550”
TELEM2=“-C /dev/ttyAMA0”
#Options to pass to ArduPilot
ARDUPILOT_OPTS=“$TELEM1 $TELEM2”
# # ###### # #####
# # # # # #
###### ##### # # #
# # # # #####
# # # # #
# # ###### ###### #
#-A is a console switch (usually this is a Wi-Fi link)
#-C is a telemetry switch
#Usually this is either /dev/ttyAMA0 - UART connector on your Navio
#or /dev/ttyUSB0 if you’re using a serial to USB convertor
#-B or -E is used to specify non default GPS
#Type “emlidtool ardupilot” for further help
Some more magic if arducopter is running by default:
pi@navio:~ $ sudo systemctl disable arducopter
Removed /etc/systemd/system/multi-user.target.wants/arducopter.service.
Then ask for ardusub to run at startup:
pi@navio:~ $ sudo systemctl start ardupilot && sudo systemctl enable ardupilot
Created symlink /etc/systemd/system/multi-user.target.wants/ardupilot.service → /etc/systemd/system/ardupilot.service.
pi@navio:~ $ sudo reboot
If Ardusub QgroundControl (Installation | ardusub-gitbook) is running on your PC, it should connect in UDP…
If you have some difficulties, ask for help,

Thanks for help. Ardusub is running now.
