TI中文支持网各位大神：
请问有跑过rfEasylink例程吗？ 我在修改为625bps rate的时候数据接收不到，请问是怎么回事？
当然发送程序也改成了625bps 速率，另外都是868频率发送。
Eggsy Pang：
可以把你在rfEasylink例程中修改的部分贴出来吗？
Levi：
回复 Eggsy Pang:
就下面两个地方，一个配置为625，另一个收的timeout改为500ms了，也试过改为1s，还是不行。
另外我把tx的修改的也贴出来吧：
这就是全部；tx没问题看到发送完成对应的灯闪烁了。

回复 Levi:
下载我们的GUI调试软件，SmartRF Studio 7，接上接收方，看看有没有收到。
Levi：
回复 Eggsy Pang:
刚测试了 没有收到数据；但是在另一个开发板上烧的rfPaketErrorRate的程序中配置成LRM模式能收到rfEasyLinkTx发送的数据。
Eggsy Pang：
回复 Levi:
可能是SmartRF Studio 7没有设置好，不过根据你说rfPaketErrorRate的程序可以接到到，证明空中有数据，rfPaketErrorRate接收方程序，是让CC1310一直出于接收情况，而rfEasyLinkRx程序，是间隔接收，你把rfEasyLinkTx例程改一下，让CC1310一直发送，试下能不能接收
Levi：
回复 Eggsy Pang:
不行啊，rx就是收不到，就算用rfPaketErrorRate发送也收不到；是不是EasyLink的接收程序有问题啊？
Eggsy Pang：
回复 Levi:
把接收的程序用文字发上来，非图片，就把main函数所在的文件的内容贴上来就行，我测试下

发送方我用的是smart RF radio 7，如图配置步骤：
