MSP430F2274 CC2500 两块无线传输模块 回传问题

使用的是IAR

动作如下：
从计算机端发送，电池模块ＬＥＤ灯亮
接着电池模块回传，计算机端ＬＥＤ灯亮

结果没回传到计算机端， 请大神看看 !

计算机传送端 代码如下:

楼主你做过无线电能传输吗?我现在做无线传输。

楼主你好：

不能通信成功只是个结果，不是问题。影响到这个结果的因素非常多，不仅仅是程序软件。

所以你要先仔细调试，可能问题不止一个。所以经过调试后，将问题问的具体一些（比如，如果是通信不上，那是一点信号都没有、是前导码都没收到?还是数据收到了，校验不过?），这样大家才能更好帮你解决问题。

如果拿个结果，没有人能回答哦。

绿茶前辈 您好:

感谢您的回复 !
真是非常抱歉没注意到细节的部分 描述不够清楚
现在疑问的点在于:

首先 , 计算机传送端的 address 设为0x02 ; 电池模组端的address 设为0x01

计算机传送端代码的 第57行 表示传给0x01(电池模组端) 一个值 'A' (第58行)
然后 第79行 rxBuffer[0]== 0x02 表示自己的 address 为0x02

电池模组端代码的 第73 行表示自己的 address 为0x01
然而因为计算机传送端传送的值是 'A' 因此电池模组端会执行 第92行的 else
接着先亮红灯 再回传给计算机传送端 0x02 (第101行)

电池模组端有亮灯 表示有收到信号并执行回传动作
但 计算机传送端并没有收到回传的值 (也就是 rxBuffer[0] 没有收到信号)
这部分是用 Add Watch 去查看的

在这之前 测试过将两端的 address 都设为 0x01
结果回传成功

但当 address 设定不是 0x01 时 回传就会失败
理论上不应该会这样, address 应该可以任意设置在 0xFF 以内才对

想请问前辈们这有可能是什么原因造成的 ?

( 目前硬体的部分测试没有问题 )

刚开始接触而已
