如果在 GATT 消息接收并通过处理发送后连接断开、如何处理存储器释放？
代码在该函数最后一行的 GATT_BM_FREE 之前达到`return；`。
这是潜在的泄漏吗？
以下代码来自 1.5.2 栈工程文件夹中的 simpleBLECentral.c。
static void simpleBLECentralProcessGATTMsg( gattMsgEvent_t *pMsg )
{
if ( simpleBLEState != BLE_STATE_CONNECTED )
{
// In case a GATT message came after a connection has dropped,
// ignore the message
return;
}
if ( ( pMsg->method == ATT_READ_RSP ) ||
( ( pMsg->method == ATT_ERROR_RSP ) &&
( pMsg->msg.errorRsp.reqOpcode == ATT_READ_REQ ) ) )
{
if ( pMsg->method == ATT_ERROR_RSP )
{
uint8 status = pMsg->msg.errorRsp.errCode;
LCD_WRITE_STRING_VALUE( "Read Error", status, 10, HAL_LCD_LINE_1 );
}
else
{
// After a successful read, display the read value
uint8 valueRead = pMsg->msg.readRsp.pValue[0];
LCD_WRITE_STRING_VALUE( "Read rsp:", valueRead, 10, HAL_LCD_LINE_1 );
}
simpleBLEProcedureInProgress = 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 == ATT_ERROR_RSP )
{
uint8 status = pMsg->msg.errorRsp.errCode;
LCD_WRITE_STRING_VALUE( "Write Error", status, 10, HAL_LCD_LINE_1 );
}
else
{
// After a succesful write, display the value that was written and increment value
LCD_WRITE_STRING_VALUE( "Write sent:", simpleBLECharVal++, 10, HAL_LCD_LINE_1 );
}
simpleBLEProcedureInProgress = FALSE;
}
else if ( simpleBLEDiscState != BLE_DISC_STATE_IDLE )
{
simpleBLEGATTDiscoveryEvent( pMsg );
}
GATT_bm_free( &pMsg->msg, pMsg->method );
}
