PinRequired value during sim initialization

PinRequired value during sim initialization

Hi,

Immediately after the 'Present' property changes to true on
org.ofono.SimManager, i read the 'PinRequired' property. Because the
sim is not yet initialized this is set to "none". It would be nice if
this was set to "notinitialized", or if there would be an additional
property to know if sim initialization is done.

Thanks,
Cedric

Hi,

I wouldn't rely on the Present property too much. I have seen modems where the SimManager interface is not even available if the SIM was missing. And I have seen modems where Present was still true after I have pulled out the SIM...

Martin

Sounds like your hardware does not support SIM hot-swap.

I do admit this is a slight inconsistency in the API.  However, 
PinRequired=none was never meant to signify that the SIM has been 
initialized.  If you want that, then you should monitor the 
'SubscriberIdentity' property.  Once that property goes live you can 
assume that the SIM has been initialized to the point that other tasks 
can be performed, e.g. going Online.  If the PIN is required then the 
PinRequired will at some point go to state other than 'none'.

In general oFono does not use 'unknown' states for any properties unless 
that is an explicit state that can be obtained from the network.  The 
best I can suggest right now is that we can make PinRequired an optional 
property; e.g. it will not be present until the PIN has been queried.

I think this is a good idea. This way there's no doubt in the pin
state when 'PinRequired' is 'none'.
