[agl-discussions] low can service

[Romain Forlot [IoT.bzh]]

Hi,

- "how do I start the default low-can-service?"

You can start the low-can service manually with the "afm-util" command

afm-util start <widget_id>

Widget id use the following format : id at version

i.e: low-can-service at 6.90

But the low-can service isn't meant to run like this, it should be used 
transparently through applications which will start it. A service is 
always available for apps or others bindings by dependency, if you 
specify that your app depends on low-can api then when the app starts, 
it will automatically start the low-can service. If you want more 
details, this dependency is implemented using systemd unit service and 
socket that are generated when you install a widget.

- "is it already installed or do I need to install it?"

yep, it is already install as a service in the default AGL image. Until 
Flounder version, you can find it in 
/var/local/lib/afm/applications/low-can-service, next version will use 
/var/local/lib/afm/applications/agl-service-can-low-level

- "in addition to the low can I start other services to connect the app 
to the can?"

Humm, I don't think that there is an existing apps that use the low-can 
API except the signal-composer for now which is also installed by 
default but the low-can configuration isn't activated by default. 
Anyway, signal-composer is also a service without UI. I suggest you to 
read the usage guide of the low-can service here : 
http://docs.automotivelinux.org/docs/apis_services/en/dev/reference/signaling/low-can-usage-guide.html 
If you haven't already read it. :)

Best regards.
