 - 解析串口数据
 解析完后需把串口接收缓存清空，以免影响下次数据的解析
 ```c
-                for (int i = 0; i < uart3Packet.len; i++)                     // parse nmea data
-                        nmea_parser_putchar(parser, uart3Packet.packet[i]);
-                uart3Packet.isValid = false;
-                uart3Packet.len = 0;
-                memset(uart3Packet.packet, 0, sizeof(uart3Packet.packet));
