can't set PIN code on a MC7430

[Christophe Ronco]

Hello,

I am trying to manage a MC7430 modem using libqmi.

After a kernel upgrade, I am now able to send basic commands to my 
modem. Example:

qmicli -d /dev/cdc-wdm0 --dms-get-ids
[/dev/cdc-wdm0] Device IDs retrieved:
          ESN: '0'
         IMEI: '359074060071935'
         MEID: '35907406007193'

I use libqmi version 1.16.2.

I am not able to send PIN code to modem. I tried the following commands:

root at klk-lpbs_040070:~ # qmicli -d /dev/cdc-wdm0 
--dms-uim-verify-pin=PIN,0000
error: couldn't verify PIN: QMI protocol error (71): 'InvalidQmiCommand'

root at klk-lpbs_040070:~ # qmicli -d /dev/cdc-wdm0 --uim-verify-pin=PIN1,0000
error: couldn't verify PIN: QMI protocol error (3): 'Internal'
[/dev/cdc-wdm0] Retries left:
         Verify: 0
         Unblock: 0

I also tried the following commands to get PIN status:

root at klk-lpbs_040070:~ # qmicli -d /dev/cdc-wdm0 --dms-uim-get-pin-status
error: couldn't get PIN status: QMI protocol error (71): 'InvalidQmiCommand'

root at klk-lpbs_040070:~ # qmicli -d /dev/cdc-wdm0 --uim-get-card-status
[/dev/cdc-wdm0] Successfully got card status
Provisioning applications:
     Primary GW:   slot '0', application '0'
     Primary 1X:   session doesn't exist
     Secondary GW: session doesn't exist
     Secondary 1X: session doesn't exist
Card [0]:
     Card state: 'present'
     UPIN state: 'not-initialized'
         UPIN retries: '0'
         UPUK retries: '0'
     Application [0]:
         Application type:  'sim (1)'
         Application state: 'pin1-or-upin-pin-required'
         Application ID:
                     Personalization state: 'unknown'
         UPIN replaces PIN1: 'no'
         PIN1 state: 'enabled-not-verified'
             PIN1 retries: '3'
             PUK1 retries: '10'
         PIN2 state: 'enabled-not-verified'
             PIN2 retries: '3'
             PUK2 retries: '10'
Card [1]:
     Card state: 'absent'
     UPIN state: 'not-initialized'
         UPIN retries: '0'
         UPUK retries: '0'

So with --uim-get-card-status, I am able to get PIN status but I don't 
know how to set PIN.

Does anyone have done that on a MC7430? Or an idea of what I did wrong?

PS: this modem also has an AT channel, I am able to set PIn using 
AT+CPIN=0000.

Best Regards,
