cc2540主机如何获得从机Notify权限的Handle

时间：10-02 整理：3721RD 点击：

版主好：

请问 cc2540主机如何获得从机Notify权限的Handle。例如在SimpleBLECentral中当是ATT_HANDLE_VALUE_NOTI消息时判断Hanlde是否等于0x0038，这个0x0038是如何得到的。

谢谢！

silver,

这个是通过characteristic 查找得到的。

很多中方法，你可以通过characteristic UUID 查找，找到这个characteristic对应的value的Handle之后，一般后面紧跟着一个就是。

我用主机 SimpleBLECentral的程序怎么读sensortag的值呢？我怎么知道sensortag 中特征值的 handle呢？

ke,

SimpleBLECentral是没有办法直接读取sensortag的值的。你得修改代码。

但是有个PC工具，BLE Device Monitor，这个工具相当好，而且对sensortag有优化，你能直接通过CC2540 dongle连接上sensortag,然后查看到sensortag里面的所有信息，包括你要的handle.

hi! YAN

我想知道SimpleBLECentral怎样修改能得到sensortag中的值，我是参考串口透传的程序修改的，但是可以使能notify，读不出值来！有实例我可以看一下吗？

我实在是看不出哪里错了？是回调程序错了吗？

这段程序是使能通知不？

req.handle = irTempDataHdl+1;//0x0026 ;//
req.len = 2;
req.sig = 0;
req.cmd = 1;
req.value[0]=0x01;
req.value[1]=0x00;

如果是的话我的程序进入不到 else if ( pMsg->method == ATT_HANDLE_VALUE_NOTI )

请问为什么？

那该如何修改？

我修改的程许在附件中

请帮我看看
