EM7455 API return error

IoT Modules MC/EM Series
1

I use EM7455 for MT7628 platform. This platform linux kernel version is 3.10. so I must use Gobinet driver and sdk. This topic does not talk about this version of the problem.

I encountered some errors when use sdk.

firmware:9999999_9904609_SWI9X30C_02.33.03.00_00_GENERIC_002.072_000.exe
sdk version:SLQS04.00.27-lite.bin.tar.gz

  1. API error when verify PIN.

  1. SIM card status not report to dms service watch.
    how can I enable report for SIM cart status(plug in/plug out) ? sdk demo have not specfic exaples.
# my Fake code
  uint8_t setInd = 0x1;

  pack_dms_SetEventReport_t dmsReqPara;
  memset(&dmsReqPara, 0, sizeof(pack_dms_SetEventReport_t));
  dmsReqPara.mode = DMS_SET_REPORT_ENABLE;
  rtn = pack_dms_SetEventReport(&req_ctx, qmi_req, &qmi_req_len, (void *)&dmsReqPara);
  //write(2);

  pack_dms_SwiSetEventReport_t SwiEventSettingsUINStatus = {NULL, NULL, &setInd};												
  rtn = pack_dms_SwiSetEventReport(&req_ctx, qmi_req, &qmi_req_len,  (void *)&SwiEventSettingsUINStatus);
// write(2);

  pack_dms_SLQSDmsSwiIndicationRegister_t dmsIndRegPara;
  memset(&dmsIndRegPara, 0, sizeof(pack_dms_SLQSDmsSwiIndicationRegister_t));
