TI中文支持网Part Number:CC1310
将 CC1310 配置为 4Mbps 的速率, 编写 no-RTOS 代码, 执行 下面的 周期性 操作:(1) 休眠 500ms 以后, 执行 无线发送状态的 配置( RF_tran_init )
(2) 然后读取 传感器信息(16个字节), 执行 无线发送 ( RF_tran_op )
(3) 启动 无线发送的 操作了, 也启动 定时器 工作; ( wait_WLpkg_tran )
(4) 如果 在1ms 内就执行了 tx_callback 中断, 则进入 下面的步骤(6);
(5) 如果 定时器 已经计时超过 1ms 了, 也跳出 无线发送的 等待过程, 进入 下面的步骤(6)
(6) 判断 是否 已经执行了 5次 上面的 操作; 如果少于 5次, 则跳转到(2)接着执行; 否则 进入(7)
(7) 执行 休眠 500ms
附件 rf_tran 4Mbps.c 包含上面的 具体代码; 也包含 简化以后的 main() 函数。
对于 main() 函数中, 也调用了 rf_recv 功能 (对应的代码, 参见 附件 rf_recv.c)
每隔500ms, CC1310读取 传感器信息, 无线发送; 执行 5次。
使用 侦听器 (另外一个 CC1310 单板, 配置为 无线接收状态), 获取上述 5次无线发送的 信息, 也用定时器 获取 5个无线包 之间的 间隔。
刚开始工作的时候, 无线发送过程中, tx_callback 中断处理都很正常; 对于 5个无线包的 4个间隔, 都是 2.4ms 附近;
但是, 工作一段时间以后, 发送无线包的间隔, 都是 3.1ms 附近 —- 没有得到 tx_callback 中断处理; 那个 1ms 的定时器, 将 代码 '拽出了' 持续等待 tx_callback 中断的 那种状态。
备注: 侦听器 始终可以 完整 获取到 每个周期内的 5个 无线包。即, 无论是否 tx_callback 中断处理, 无线发送的操作, 都是顺利完成了, 可以被 无线接收到。
有时候, 持续工作十几个小时, 才出现上述 3.1ms 的问题; 有时候, 半个小时以后就出现 上述问题了。
出现上述问题以后, 不能自动恢复, 这个问题 会持续存在。 只有将 单板掉电重启, 才能恢复正常。 备注：上面的操作(1)， 对 CC1310 执行 全部的、配置 4Mbps、执行 无线发送的、 初始化操作
上述 rf_tran 4Mbps.c 文件中, 将 CC1310 配置为 4Mbps 速率的代码, 都是参照 TI 例程 rfPacketErrorRate, 相应 '摘取' 得到。
请帮忙指点一下, 是否上述 代码中, 漏掉了 某个关键的 处理, 然后 导致 某种状态下, 触发了某种异常情况, 于是 无线包 成功发送了, 却 没有 能够 产生 tx_callback 中断？

Alex Zhang：
您好，已经跟进您的问题，这需要一些时间，谢谢。
,
Alex Zhang：
我不确定我是否完全理解您的 HSM 问题是什么。
我采用了 rfPacketTX 和 rfPacketRX 示例（4.20 SDK 中没有 rtos 版本），并将其修改为使用 4 mbps PHY 并每 500 毫秒发送/接收 5 个长度为 300 字节的数据包。
请看一下这个示例，看看您是否可以启动并运行它。
如果您需要更改代码以适合您的应用程序，请这样做，如果它开始失败，您可以与我分享修改，以便我可以在这里测试它并看看发生了什么。
当你的代码不是完整的示例时，我很难调试它。
附上我修改后的文件。
