Hello,

I have an issue in the example of basic_ble_profiles. I have activated the Glucose profile and modified the example to send a Glucose measurement notification every 1 minute. I have run the example and established a connection with the mobile app and activated the notification of the Glucose Measurment characteristic through the mobile app. When the application came to the GATT_Notification function, it didn't sent any notification to the central and returned a status code (5) although it wasn't mentioned in the API documentation of that function. I have searched for that error code and found that it means an INVALID_MSG_POINTER, but I debugged the code and found pointers sent to the function were valid. What can the problem be??

static bStatus_t GLS_sendNotiInd(uint8 *pValue, uint16 len, gattCharCfg_t *charCfgTbl, uint8 *pAttValue)
{
  bStatus_t status = SUCCESS;
  gattAttribute_t *pAttr = NULL;
  attHandleValueNoti_t noti = {0};
  linkDBInfo_t connInfo = {0};
  uint16 offset = 0;
  uint8 i = 0;

  // Verify input parameters
  if (( charCfgTbl == NULL ) || ( pValue == NULL ) || ( pAttValue == NULL ))
  {
    return ( INVALIDPARAMETER );
  }

  // Find the characteristic value attribute
  pAttr = GATTServApp_FindAttr(gls_attrTbl, GATT_NUM_ATTRS(gls_attrTbl), pAttValue);
  if ( pAttr != NULL )
  {
    for ( i = 0; i < MAX_NUM_BLE_CONNS; i++ )
    {
      gattCharCfg_t *pItem = &( charCfgTbl[i] );
      if ( ( pItem->connHandle != LINKDB_CONNHANDLE_INVALID ) &&
           ( pItem->value != GATT_CFG_NO_OPERATION) )
      {
        // Find out what the maximum MTU size is for each connection
        status = linkDB_GetInfo(pItem->connHandle, &connInfo);
        offset = 0;

        while ( status != bleTimeout && status != bleNotConnected &&  len > offset )
          // Determine allocation size
        {
          uint16_t allocLen = (len - offset);
          if ( allocLen > ( connInfo.MTU - GLS_NOTI_HDR_SIZE ) )
          {
            // If len > MTU split data to chunks of MTU size
            allocLen = connInfo.MTU - GLS_NOTI_HDR_SIZE;
          }

          noti.len = allocLen;
          noti.pValue = (uint8 *)GATT_bm_alloc( pItem->connHandle, ATT_HANDLE_VALUE_NOTI, allocLen, 0 );
          if ( noti.pValue != NULL )
          {
            // If allocation was successful, copy out data and send it
            VOID memcpy(noti.pValue, pValue + offset, noti.len);
            noti.handle = pAttr->handle;
            if( pItem->value == GATT_CLIENT_CFG_NOTIFY )
            {
              // Send the data over BLE notifications
              status = GATT_Notification( pItem->connHandle, &noti, TRUE );
            }
            else if ( pItem->value == GATT_CLIENT_CFG_INDICATE )
            {
              // Send the data over BLE indication
              status = GATT_Indication( pItem->connHandle, (attHandleValueInd_t *)&noti, TRUE, INVALID_TASK_ID);
            }
            else
            {
              // If Client Characteristic Configuration is not notifications/indication
              status = INVALIDPARAMETER;
            }

            // If unable to send the data, free allocated buffers and return
            if ( status != SUCCESS )
            {
              GATT_bm_free( (gattMsg_t *)&noti, ATT_HANDLE_VALUE_NOTI );

              // Failed to send notification/indication, print error message
              MenuModule_printf(APP_MENU_PROFILE_STATUS_LINE4, 0,
                                "Failed to send notification/indication - Error: " MENU_MODULE_COLOR_RED "%d " MENU_MODULE_COLOR_RESET,
                                 status);
            }
            else
            {
              // Increment data offset
              offset += allocLen;

              // Notification/indication sent
              MenuModule_printf(APP_MENU_PROFILE_STATUS_LINE4, 0,
                                "Notification/indication sent");
            }
          }
          else
          {
            status = bleNoResources;
          }
        } // End of while
      }
    } // End of for

  return ( status );

Thank you in advance!
