你好，
请问哪里可以下载到CC1310在LRM模式下4.8K通信的例程。
RF studio 里面只有625波特率的代码。我们需要用到4.8K的波特率。
谢谢!
下载地址在这里： http://dev.ti.com/tirex/#/?link=TI-RTOS%20for%20CC13XX%20and%20CC26XX%2FDevelopment%20Tools%2FCC1310DK_7XD%2FDriver%20Examples%2FRF%20Examples
LONG LI8,
TI-RTOS中的RF drivers里面应该可以找到Tx/Rx的示例代码，你可以修改看看。
如果你有CCS，直接用里面的resource explorer找到工程，如果没有CCS，建议你下载安装一下，如果不能安装，你也可以直接去浏览TI-RTOS的安装目录找到代码。
Viki,
你好。能帮忙指出具体哪个例程是 LRM 模式 4.8K bps吗？或者提供一份关于LRM模式下的配置说明文档。
你给出的链接我全部下载下来了，全部是FSK调制模式。
Long,
这些例程全是FSK调试模式，传输距离很近。
我需要的是LRM调制模式的例程。
LONG 你好
4.8k的LRM，我帮你测好了，你把“smartrf_settings.c" 里面的代码改为我下面这个：
