Hi Vincent,
So the applications would need to poll these values. Does the modem
enable some sort of unsolicited notifications of these?
No unsolicited notifications for voltage.
There are notifications for over/under temperature warning,
but exact value must be polled.
Okay. In that case a method call is probably the best way to do this.
I would combine the two method calls into one. e.g. GetStatistics()
that would return a dictionary of values. Something like:
a{sv} GetStatistics()
where s is the key:
"Voltage" - uint32 (I assume this can't be negative)
"Temperature" - int32
This keeps your round-trips to a minimum. It takes ages to go over
D-Bus, so it should be considerably faster to have oFono query both
values at once. Especially if you can combine the query into a single
AT commmand.
Might want to mention the units as well. F vs C, etc.
How would you implement the notification? With a property and a signal
PropertyChanged? Is it ok to keep the methods as I propose, and add
the notification later?
If it is just a plain notification that e.g. a temperature exceeds the
threshold, then I would model it as a signal. Something like:
TemperatureThresholdExceeded()
Is there a way to set the threshold?
Regards,
-Denis
