# dynamic_electrocardiograph_ble_server
```
V1:
1.会自动搜索包含下面服务的设备然后进行连接
6e400001-b5a3-f393-e0a9-e50e24dcca9e
2.支持以下UUID服务
6e400001-b5a3-f393-e0a9-e50e24dcca9e
6e400002-b5a3-f393-e0a9-e50e24dcca9e

6e400004-b5a3-f393-e0a9-e50e24dcca9e
3.接收到的蓝牙数据包，会在结尾添加
0x5A 0xA5
4.如果2ms内没有收到新的串口数据，会将之前收到的数据当作一包数据，发给蓝牙从机
```
