[Ovmsdev] test works, what next

[Michael Balzer]

Nikolay,

congratulations :-)

Mark already said it: look for "car_" variables, these will transport 
common properties. "can_" variables are currently vehicle locals, see my 
previous suggestion on renaming these to reflect their vehicle specific 
nature. Only common properties and commands will currently be supported 
by the Apps -- adding vehicle specific code and UIs to the Apps is the 
next main todo.

Note there are some variables already in the Twizy code, that 
could/should become common. Generally, the more vehicles turn up to need 
some value, the more likely it will become common.

Without App support, you still can do vehicle specific data collection 
and analysis by sending "H" MSGs to the server. "H" msg types are 
basically free-form, they can transport all vehicle specific data to the 
server and to any client. There are multiple examples in the Twizy code 
for that, and I've added user guides and a perl utility "cmd.pl" to 
query them from the server last night, take a look. The output is simple 
CSV format, so you can load that into any spreadsheet or database.

For text messages, note there is already an App msg defined ("P" = push 
message), the only current caveat is, the Apps (at least the Android 
one) will only process these if backgrounded. That certainly can be 
fixed soon, so push messages will become a fully functional SMS alternative.

Regards,
Michael
