CCS/CC2650EM-7ID-RD: Why GATT_DiscAllChars() can only found 3 handles, but not all handles

Hey Jacob,

I have it set to MAX_PDU_SIZE=70 and I am able to find the three five pairs.
Can you try that out?

Edit: Meant to say five not three

Jacob,

Oh my apologies. I meant to say 5 pairs in my reply.

With the MAX_PDU_SIZE set to the higher value, yes I am. Here is my relevant code snippet from SimpleBLECentral_processGATTDiscEvent:

 else if (discState == BLE_DISC_STATE_SVC)
  {
    // Service found, store handles
    if (pMsg->method == ATT_FIND_BY_TYPE_VALUE_RSP &&
        pMsg->msg.findByTypeValueRsp.numInfo > 0)
    {
      svcStartHdl = ATT_ATTR_HANDLE(pMsg->msg.findByTypeValueRsp.pHandlesInfo, 0);
      svcEndHdl = ATT_GRP_END_HANDLE(pMsg->msg.findByTypeValueRsp.pHandlesInfo, 0);
    }

    // If procedure complete
    if (((pMsg->method == ATT_FIND_BY_TYPE_VALUE_RSP) &&
         (pMsg->hdr.status == bleProcedureComplete))  ||
        (pMsg->method == ATT_ERROR_RSP))
    {
      if (svcStartHdl != 0)
      {
        attReadByTypeReq_t req;

        // Discover characteristic
        discState = BLE_DISC_STATE_CHAR;
        VOID GATT_DiscAllChars(connHandle, svcStartHdl,svcEndHdl, selfEntity);
      }
    }
  }
  else if (discState == BLE_DISC_STATE_CHAR)
  {
    // Characteristic found, store handle
    if ((pMsg->method == ATT_READ_BY_TYPE_RSP) &&
        (pMsg->msg.readByTypeRsp.numPairs > 0))
    {
      uint8_t numPairs = pMsg->msg.readByTypeRsp.numPairs; // this returns 5
      
      Display_print1(dispHandle, 3, 0, "Num Pairs: %d", numPairs);
      
      charHdl = BUILD_UINT16(pMsg->msg.readByTypeRsp.pDataList[0],
                             pMsg->msg.readByTypeRsp.pDataList[1]);

      Display_print0(dispHandle, 2, 0, "Simple Svc Found");
      procedureInProgress = FALSE;
    }

    discState = BLE_DISC_STATE_IDLE;
  }

Here's a screenshot of my locals window showing numPairs is 5:
