in an embedded linux application we are already using the MC7304 and now we want to evaluate the mc7455.
We have a c written modem control-sw which is using the slqsdk api.
In that sw we requesting the pin-status of the inserted card, and here we have a problem with the mc7455.
If we issue the “SLQSUIMGetCardStatus” command, the response contains a invalid pin-status (0, unknown).
At the opposite a AT+CPIN returns the correct READY state.
The old modem is using the UIMGetPinStatus which is working for the MC7304, but the MC7455 returns QMI invalid command so we have to use the newer command.
I think here is something broken in the SDK.
