Handle discovering with GATT_DiscAllChars()

Other Parts Discussed in Thread: CC2650, CC2540

Hello,

I saw many and many other topics with the same subject but no one is reponding to my issue.

I'm using the CC2650 with a central and tried to discover the 5th "simple profiles" of my peripheral.

To do that I did on the SimpleBLECentral_handleKeys() :

if (keys & KEY_DOWN)
{

     if (state == BLE_STATE_CONNECTED)
     {
        status = GATT_DiscAllChars(connHandle,(uint16_t)0,(uint16_t)65000,selfEntity);
     }
}

And on the  SimpleBLECentral_processGATTMsg() I add a case with the ATT_READ_BY_TYPE_RSP answer which gives :

static void SimpleBLECentral_processGATTMsg(gattMsgEvent_t *pMsg)
{

static uint8_t led;

  if (state == BLE_STATE_CONNECTED)
  {
    // See if GATT server was unable to transmit an ATT response
    if (pMsg->hdr.status == blePending)
    {
      // No HCI buffer was available. App can try to retransmit the response
      // on the next connection event. Drop it for now.
      Display_print1(dispHandle, 4, 0, "ATT Rsp dropped %d", pMsg->method);
    }

    else if ((pMsg->method == ATT_READ_RSP)   ||
             ((pMsg->method == ATT_ERROR_RSP) &&
              (pMsg->msg.errorRsp.reqOpcode == ATT_READ_REQ)))
    {
      if (pMsg->method == ATT_ERROR_RSP)
      {
        Display_print1(dispHandle, 4, 0, "Read Error %d", pMsg->msg.errorRsp.errCode);
      }
      else
      {
        // After a successful read, display the read value
    	led=pMsg->msg.readRsp.pValue[0];
    	Display_print1(dispHandle, 6, 0, "Nombre valeurs lue: %d", pMsg->msg.readByTypeRsp.numPairs);
        Display_print1(dispHandle, 4, 0, "Read rsp: %d", led);
      }

      procedureInProgress = FALSE;
    }
    else if ((pMsg->method == ATT_WRITE_RSP)  ||
             ((pMsg->method == ATT_ERROR_RSP) &&
              (pMsg->msg.errorRsp.reqOpcode == ATT_WRITE_REQ)))
    {
      if (pMsg->method == ATT_ERROR_RSP)
      {
        Display_print1(dispHandle, 4, 0, "Write Error %d", pMsg->msg.errorRsp.errCode);
      }
      else
      {
        // After a successful write, display the value that was written and
        // increment value
        Display_print1(dispHandle, 4, 0, "Write sent: %d", charVal++);
      }

      procedureInProgress = FALSE;

    }
    else if (pMsg->method == ATT_FLOW_CTRL_VIOLATED_EVENT)
    {
      // ATT request-response or indication-confirmation flow control is
      // violated. All subsequent ATT requests or indications will be dropped.
      // The app is informed in case it wants to drop the connection.

      // Display the opcode of the message that caused the violation.
      Display_print1(dispHandle, 4, 0, "FC Violated: %d", pMsg->msg.flowCtrlEvt.opcode);
    }
    else if (pMsg->method == ATT_MTU_UPDATED_EVENT)
    {
      // MTU size updated
      Display_print1(dispHandle, 4, 0, "MTU Size: %d", pMsg->msg.mtuEvt.MTU);
    }
    else if (discState != BLE_DISC_STATE_IDLE)
    {
      SimpleBLECentral_processGATTDiscEvent(pMsg);
    }
    else if (pMsg->method == ATT_READ_BY_TYPE_RSP)
    {
  	  Display_print1(dispHandle, 6, 0, "Nb valeurs lue: %d", pMsg->msg.readByTypeRsp.numPairs);
    }
  } // else - in case a GATT message came after a connection has dropped, ignore it.

  // Needed only for ATT Protocol messages
  GATT_bm_free(&pMsg->msg, pMsg->method);
}

I never saw the case with ATT_READ_BY_TYPE_RSP works so I took the CC2540miniDK dongle and used it as sniffer (BTW I hope to use the CC2540 dongle isn't bad to work with CC2650)

I got five "ATT_READ_BY_TYPE_RSP" and took the screen :

I'm joinning you the file which contains the record of this picture (Open with Packet Sniffer from TI).

I need to understand 2 things here :

1/ Why did I never get the "ATT_READ_BY_TYPE_RSP" case on my SimpleBLECentral_processGATTMsg() function ?

2/ Can I read the handles of my 5 simpleprofiles from the sniff ?

Thank you by advance.

Best regards,

John.
