您好！
我正在使用 rfEchoTx 和 rfEchoRx 项目处理一个项目、我每1分钟从 emmiter 发送数据。 前2-3个数据发送正常、但之后、程序在发送事件发生时卡住("rfEchoTx.c"中的第405行)。 我试图找到一个原因、但我不知道 为什么会发生这种情况。 有什么想法吗？
我附上相应的项目。
e2e.ti.com/.../rfEchoTx_5F00_CC1310_5F00_LAUNCHXL_5F00_tirtos_5F00_ccs.zip
e2e.ti.com/.../rfEchoRx_5F00_CC1310_5F00_LAUNCHXL_5F00_tirtos_5F00_ccs.zip
提前感谢、
Alberto
我不确定我是否理解您在代码中执行的所有计时操作、因此我不清楚您尝试执行的操作。
为了缩小问题范围、我本来应该删除所有 ADC 内容、首先尝试使用正确的时序和数据包大小来实现通信。
如果发送时遇到问题、则需要查看 应用程序卡住时 RF_runCmd 命令内部发生的情况(使用调试器并查看代码在 RunCommand 中的挂起位置)。
要调试 RunCommand、需要手动将 rfdriver 文件添加到项目中。
此外、您应该在代码挂起时查看不同命令的状态、以指示问题可能是什么。

您好、Siri、
I debugRunred Command、程序在此行中暂停。 如图所示、它出现在 RFCC26XX_MODEX.c 文件中的4452行中。 您是否对暂停的原因有任何了解？
在该命令行内、它在这里停止(swip_tirtos.c)。
简而言之、我的项目是每小时保存数据、并在特定的时间发送数据包、同时发送所有测量值、这就是我使用 TM 结构来设置本地时间的原因。 为了检查它是否工作得更快、我将在最初几分钟内发送数据。 我希望这可以帮助您更好地了解我的项目。
执行一些测试后，我认为 在使用 Task_sleep()和数据发送时应该会有一些问题。 独立于任务定期进入睡眠状态的时间、程序在4-5分钟数据发送后停止。 但是，如果我删除 Task_sleep()程序，它始终可以正常工作。
此致、
Alberto
关于您的问题、TX 代码可以在没有 rfEchoRX 示例的情况下运行。 在这种情况下、它会持续发送数据包、直到 RX 接收到数据包。
我采用了原始 rfEchoTX、如果未修改、它将正常工作。 但是、如果我在文件 rfEChosx.c 的 while 循环中添加 sleep 或 Task_sleep（)(第238行)、它在运行4分钟后也会失败、正如我之前的项目所发生的那样。

我还看到代码停止发送、但我无法看到它停留在您所看到的相同位置。 对我来说、它看起来就像睡得太久了。
但是、代码中的更改毫无意义。
演示代码使用绝对触发器将发送器设置为每1s 传输一次数据包、然后在中间自动进入待机状态。 当前时间只读取一次
curtime = rf_getCurrentTime()；
所有其他时序都是通过向该初始读取值添加1来设置的。
curtime += packet_interval；
当您突然在循环中添加睡眠(60)时、下一个数据包的计划时间早就该过了。
您应该使用 trig_ABSTIME 并将数据包间隔(packet_interval)设置为一个值、使您的间隔为60秒而不是1秒、或者您应该使用 trig_now、并让应用程序负责睡眠的时序和进入。
Siri
非常感谢您的帮助、现在它可以正常工作了。
无论如何、我需要每小时存储一些温度和电池电压数据、每次 测量之间都将进入待机状态。 存储12次测量后、通过 RF 发送。 因此、LP 应在每次测量时进入待机状态、而无需发送数据射频。
如果我理解得好、 CC1310将进入待机状态、并根据 PACKE_INTERVAL 值在 RF_runCmd 线路等待一段时间。 我是否可以 使用 待机来存储测量值、而无需后续发送数据？
Alberto
使用 TRIG_NOW 命令执行 RX 命令，使用 SLEEP (5*60)进入待机状态。
在循环中、您将每5分钟唤醒一次、进行测量并增加计数器。
如果计数器的值为12、则表示一个小时(12 x 5分钟)后、您将传输一个数据包。
下面的伪代码：
uint8_t measurementCounter = 0;
while(1)
{
// Take a measurement
measureSomethingandStore();
measurementCounter++;
if (measurementCounter == 12)
{
// Transmit packet using TRIG_NOW
RF_runCmd();
measurementCounter = 0;
}
// Sleep for 5 minutes
sleep(5*60);
}
Siri
您好、Siri、
我正在使用 TRIG_NOW 更改"rfEchoTx.c"中的194行并实现以下代码、但它持续等待、就像以前一样。
