commandline introduction
This page explains the software development oriented tools, tricks & tips.
There are also more operational commands, see here.
Note that below examples use DbusCli (executable name: dbus). It is pre-installed on the CCGX, and can also be installed on your development computer. There are alternatives as well, see dbus-send.
Get a list of all dbus services
dbus -y
Get all paths of the com.victronenergy.settings service
dbus -y com.victronenergy.settings
Read a value
dbus -y com.victronenergy.settings /Settings/Logscript/Enabled GetValue
Read all values (works with most services, except some of the Python services including localsettings).
dbus -y com.victronenergy.solarcharger.ttyO2 / GetValue
Write a value
dbus -y com.victronenergy.settings /Settings/Logscript/Enabled SetValue %1
See the dbus interface
dbus -y com.victronenergy.settings /Settings/Logscript/Enabled
dbus-spy is an ncurses tool, which shows a list of all com.victronenergy.* services on the D-Bus, and all paths and values within each service. The values are updated in real-time and can be changed.
The interface works somewhat like the CCGX gui:
- up/down keys: move up and down in the menus
- right/left: move in and out submenus
- enter: enter a submenu or change a value.
- 't': switch between values and texts.
- ctrl-c or 'q': close the application
Besides above there is also the very cool Favorites
function. See f and F in the Readme for details.
Caveat: by default dbus-spy will only show the values of D-Bus services which support a GetValue on '/', because finding all paths without this feature will take a long time, and a lot of D-Bus communication. If you want the content of the other services as well, start dbus-spy with the -i option and be patient.
dbus-send is a faster, but somewhat more complicated to use, alternative for dbus-cli as used in previous paragraph.

Note that Venus updates are image based. See the swupdate issue.
The package manager, opkg, is still available. And can be used to install optional installs.
root@ccgx:~# opkg list-installed
base-files - 3.0.14-r76
base-passwd - 3.5.26-r0
bash - 4.2-r5
...
websockify-c - v0.8.0-r1
wget - 1.14-r16.2
wpa-supplicant - 2.2-r1
wpa-supplicant-cli - 2.2-r1
wpa-supplicant-passphrase - 2.2-r1
zip - 3.0-r1
/opt/colorcontrol/opkg-scripts/set-feed
Then update the package list
opkg update
Then install a package
opkg install [name of package here]
To find other packages, such as gdb, do:
opkg list | grep gdb
Configure the ipaddress:
export CURRENTIP=192.168.4.108
First arrange auto-login by using ssh-copy-id to all ipnumbers you want to look at.
ssh-copy-id root@$CURRENTIP
Check that you have the right one
ssh root@$CURRENTIP "ifconfig"
Then copy past below lines.
ssh root@$CURRENTIP "cat /log/vrmlogger/* | tai64nlocal"
ssh root@$CURRENTIP "cat /log/vrmpubnub/* | tai64nlocal"
ssh root@$CURRENTIP "cat /log/mk2/* | tai64nlocal"
ssh root@$CURRENTIP "cat /log/dbus-pvinverter-vebus/* | tai64nlocal"
ssh root@$CURRENTIP "cat /log/dbus-systemcalc-py/* | tai64nlocal"
ssh root@$CURRENTIP "cat /log/vecan/* | tai64nlocal" (note, starting message is not in the logs)
ssh root@$CURRENTIP "cat /log/messages.2 /log/messages.1 /log/messages.0 /log/messages | tai64nlocal"
ssh root@$CURRENTIP "cat /log/messages.2 /log/messages.1 /log/messages.0 /log/messages | tai64nlocal | grep Aligment"

The serial starter takes care of starting the drivers for built-in ttys (VE.Direct and VE.Bus ports), as well as all serial devices that are connected through USB, ie the plug-and-play work.
To work on a port yourself, you need to tell serial-starter to leave a tty alone. These commands exist for that purpose:
/opt/victronenergy/serial-starter/stop-tty.sh ttyUSB0
/opt/victronenergy/serial-starter/start-tty.sh ttyUSB0
Once serial-starter has backed off (tip: use ps to make sure), some example commands that can be used to see the output are these:
root@raspberrypi2:~# stty -F /dev/ttyUSB0 115200
root@raspberrypi2:~# cat /dev/ttyUSB0
/XMX5LGBBFG1009224834
1-3:0.2.8(42)
0-0:1.0.0(171227232200W)
0-0:96.1.1(4530303330303033313536383532323135)
...
More detail information is in the Howto add a driver to Venus document.
the trick is to leave dbus-modem running, since it resets the watchdog; kill it, and you'll loose the modem all the time.
So instead, stop ppp, and use its interface:
svc -d /service/ppp
screen /dev/modem
To get out of screen, use ctrl-a d to get back into the shell. And then don't forget to kill screen if you're done. Or kill it, with ctrl-a \
