TI中文支持网Part Number:CC1352P
请教一下，如何使用两台CC1352P-2 Development Kit开发板，利用样本程序，想实现两台机器的连续无线通讯。
使用甲PC机输入一串字符到单片机，另一台单片机接受字符串后在乙PC机上显示。
单独无线通讯，和单独PC到芯片的通讯通过DEBUG已经试通，但PC到无线通讯再PC接收一直没有试通，想请教一下大家。
我PC到单片机通讯利用的是 uart2callback_CC1352P_2_LAUNCHXL_tirtos_ccs
单片机到单片机无线通讯利用的是 rfPacketRx_CC1352P_2_LAUNCHXL_tirtos_ccs
下面是我修改过的rfPacketRx_CC1352P_2_LAUNCHXL_tirtos_ccs
无线送信端我是用了rfListenBeforeTalk_CC1352P_2_LAUNCHXL_tirtos_ccs，改造成每秒发射一组30byte的固定数字。
现在问题是，在下面source 289行，终端中加中断点时，开启无线送信，接入DEBUG，
可以看到无线收信发生，收到数据也对，
然后继续运行在265行，将数据送到PC上。
但是，不加中断点时，直接运行，PC上看不到接收到的数据。
直接运行，运行中在289行加上中断点，程序也可以停下，然后运行到265行将数据送到PC上。
但这个操作几次之后，无线信号再也不能接受数据了，可能发生了溢出错误，这个也不知如何处理。
感觉运程设计可能有些问题，请指点一下。

Kevin Qiu1：
使用例程rfPacketTx搭配rfPacketRx会简单一些，最后再将串口的程序添加进去
,
XIAOHONG ZOU：
无线搭配哪种都没问题，我的问题是串口添加进去后，无线收信的数据不能通过串口输出到PC，不知道为什么。同样 PC的数据传进单片机后，也不能发射无线信号。是串口和无线两个功能合并的问题。
其实我的问题是rfPacketTx或者rfPacketRx 怎么加入uart的问题。另外还有我想同一块板能进行rfPacketT和rfPacketRx 的切换，请问如何做？是否有例子？

Kevin Qiu1：
添加uart到rfPacketTx和rfPacketRx参考这里的回复 https://e2echina.ti.com/support/wireless-connectivity/sub-1-ghz/f/sub-1-ghz-forum/204857/cc1310-rf_packetrx
Tx和Rx切换参考这里的实现方式：https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_otherwireless_cc1310-tx-rx-uart
