Hi Aniello,
You got a mistake in your arguments, you should use:
|low-canwrite{"signal_name":"engine.speed","signal_value":1256} |
Instead of
|low-canwrite{"signal_name":"engine.speed","value":1256} |
Also be informed that not all the signals are writable, you have to
change or add the boolean value "writable" to true in your JSON signal
definitions to be able to write on them. By default, only the HVAC
signals are writable, so you have to change the signals.json in the
examples/agl-vcar directory and use the low-can-generator[1] to generate
the application-generated.cpp file.
Best regards.

Dear all,
I'd like to do some tests with the low CAN capabilities of this
project and all I've managed to do, as of now, is downloading and
installing the latest release (6.0.0) on a Raspberry Pi 3, setting up
a virtual can device and read/write from/to the bus with cansend and
candump commands.
My biggest concern is now on writing on it using the low-can api, but
for some reason I cannot manage to do so. Whenever I try to send a
message of the form
|low-canwrite{"signal_name":"engine.speed","value":1256}|
what I get in response in the shell where I launched the service is
ERROR: [API low-can] Request argument malformed. Please use the
following syntax:
[/usr/src/debug/agl-service-can-low-level/6.90.0-r0/git/low-can-binding/binding/low-can-cb.cpp:530,write]
What am I doing wrong? Also, to be clear, I skipped the whole section
about the definition of new signals as it would be enough for me to
use the default ones.
Thanks in advance!
Nello
