You would have to check the logic inside get_card_status_cb() to figure out why
the sim isn't being detected.
Hi,
Thanks for the hint. I looked into the source code of ofono and had identified
the condition on which the sim card detection logic fails.
The function handle_get_card_status_result() returns failure. The Verizon SIM
I used has 4 application running. The output of qmicli is shown below:
# qmicli -d /dev/cdc-wdm1 --uim-get-card-status [/dev/cdc-wdm1] Successfully
got card status Provisioning applications:
Primary GW: slot '0', application '2'
Primary 1X: slot '0', application '0'

The sim detection logic fails in the condition :
if ((index & 0xff) == i && (index >> 8) == n) {
if (get_card_status(slot, info1,
info2,sim_stat))
{
res = GET_CARD_STATUS_RESULT_TEMP_ERROR;
}
else
{
res = GET_CARD_STATUS_RESULT_OK;
}
}
In the condition check the slot number and application number is interchanged.
After fixing this, I could see that ofono is successfully detecting the sim
cards.
I will send a patch in my next e-mail
Attached the patch to fix this issue. Please integrate it to the ofono .
