1、获取 Connection Handle

case GAP_LINK_ESTABLISHED_EVENT:      {        if ( pEvent->gap.hdr.status == SUCCESS )        {                    simpleBLEState = BLE_STATE_CONNECTED;          simpleBLEConnHandle = pEvent->linkCmpl.connectionHandle;          simpleBLEProcedureInProgress = TRUE;              // If service discovery not performed initiate service discovery          if ( simpleBLECharHdl == 0 )          {            osal_start_timerEx( simpleBLETaskId, START_DISCOVERY_EVT, DEFAULT_SVC_DISCOVERY_DELAY );          }          LCD_WRITE_STRING( "Connected", HAL_LCD_LINE_1 );          LCD_WRITE_STRING( bdAddr2Str( pEvent->linkCmpl.devAddr ), HAL_LCD_LINE_2 );           }        else        {          simpleBLEState = BLE_STATE_IDLE;          simpleBLEConnHandle = GAP_CONNHANDLE_INIT;          simpleBLERssi = FALSE;          simpleBLEDiscState = BLE_DISC_STATE_IDLE;          LCD_WRITE_STRING( "Connect Failed", HAL_LCD_LINE_1 );          LCD_WRITE_STRING_VALUE( "Reason:", pEvent->gap.hdr.status, 10, HAL_LCD_LINE_2 );        }      }      break;

2、获取 Connection Handle

//!< Connection Handle. Read Only. Size is uint16.#define GAPROLE_CONNHANDLE          0x30E //eg: GAPRole_GetParameter( GAPROLE_CONNHANDLE, &gapConnHandle );
