CC1310: CC1310 如何修改通信模式？

?? ?

Part Number: CC1310

我需要根据不同的空速修改不同的模式，如下图所示，例如我625空速使用的legacy long range模式，当我切换到5k空速时，我希望使用simplilink long range。

根据各空速生成的smartrf_settings.c文件进行文件对比，我将其中的不同参数已经了修改，但是发现修改后仍然无法通信，我需要知道生成的smartrf_settings.c里面的参数在我主函数哪一步之前调用的，以及如何才能进行参数修改以及切换。下图是修改的部分参数截图，以及在RF初始化之前进行的修改语句。

使用搜索功能，看不到smartrf_setting.c的参数赋值的位置。

您好，

我不确定我是否理解您的问题和您给出的显示的数字。

如果您想要同时使用传统 lrm (625 bps) 和 SimpleLink lrm (5 kbps)，您需要在 smartrf_settings 文件中包含这两种模式的所有设置、覆盖、补丁：

在PHY间更改，您可以简单地用一个 PHY 打开 RF drive，做任何您想做的事情，然后关闭drive，然后用另一个 PHY 再次打开它。

Smartrf Studio中导出的代码同时只会给你一个PHY，所以你首先要导出一个PHY，重命名它，然后导出另一个，并将设置粘贴到第一个的文件中（或者可以在代码中有两个不同的SmartRF_settings文件，不同的 PHY 具有不同的名称。）
