蓝牙问题。请真正的c#高手帮忙？谢谢
.NET高手求救啊？最近开发一个蓝牙的项目。但是遇到了问题一直都无法解决。希望csdn中的 高手尽快帮忙解决啊？ 我在网上找了好多的资料和demo，资料上都是说调用系统的api就可以了。 但是我运行的时候总是说提示Btdrt.dll，ws2.dll ,无法加载等错误信息。我用的系统是xp的。在2003上面也运行过。但是都是同样的错误。还有另外一种方式也是用32feet

C# 多输入设备识别 扫码枪键盘区分RAWINPUT原始输入简易开发笔记
工作需要写了一个小程序，结合cefsharp利用erp软件的api进行二次开发，实现定制功能。软件会用到扫码枪扫描快递单号发货。会用到蓝牙电子称称重。还会遇到快递拆单快速新建订单并打印订单，也需要用到扫码枪扫描快递单，然后新建指定数量新的快递单。开发中遇到很多问题。比如，扫码枪会认定为keyboard。蓝牙接收器也会认定为keyboard。加上自身的键盘。这么多的输入设备，如果遇到2个或者2个以上输入设备同时输入就会产生干扰。不能同时输入。针对这个问题，查了很多资料发现rawinput原始输入才是解决这个问
笔记 BLE 发送超过20个字节的处理方法
写给自己备忘： 最近在写一个生产用的小程序时遇到的一个问题，之前用BLE蓝牙发送数据一般不超过10个字节，所以从来没有遇到过超过20个字节的情况。 出现的现象就是发送的数据被截断了，超过20个字节的部分被抛弃。收到的数据只有20个字节。 开始只修改了蓝牙底层#define UART_SERVER_MTU_DFT 23的这个数据，把23改为了53，测试依然是只能20个字节，从网上查找解决方法，多数说分包发送，但是这里发送的是AT命令，分包发可能会有问题，然后看到有个安卓的接口可以修改MTU数据长度，于.
