CC2642R: 调用GapScan_Enable()后程序跑飞了

如果不调用GapScan_Enable()程序一切正常，如果调用GapScan_Enable()，程序在退出ScanCallback()之后会进入RF_swiHw()，在运行到该函数的最后一句SwiP_or()之后就无法继续跟踪，应该是跑飞了，之后陷入死机。

Scanner的参数是GapScan_Enable(0，100， 20)，GapScan_setPhyParams(DEFAULT_SCAN_PHY, SCAN_TYPE_ACTIVE, 500, 100)。

Nick Sun：

您好，

您这边在使用cc2642r做什么应用的开发，在使用的SDK是什么，我们希望要有更多的图文细节，有比较完整的程序也可以一并贴上来方便我们工程师查找问题（插入代码）。

感谢您的支持。

z yy：

SDK是simplelink_cc13x2_26x2_sdk_5_10_00_48，编译软件是CCS，目前想用CC2642作为主机连接从机CC2640，这是simple_central的代码，我目前想要启动扫描并且连接我想要的那个设备。但是扫描启动之后程序容易跑飞

Nick Sun：

您好，

收到您的问题了，我们升级到英文论坛给工程师看下，有答复尽快给到您。

,

z yy：

似乎陷入了死循环，但是不知道这部分汇编代码对应哪里

,

Nick Sun：

您好，

帮您同步问题，感谢您的支持。

,

Nick Sun：

您好，

我们工程师建议您删除 SimpleCentral_scanCb() 函数中添加的代码，以方便我们去查找问题。

,

z yy：

尝试过 SimpleCentral_scanCb() 第一行就return，还是会跑飞。似乎不管这个函数里面写了什么，只要进入这个函数就会跑飞

Nick Sun：

您好，

帮您同步工程师，感谢您的支持。

Nick Sun：

您好，

因为很多程序都在背后运行，所以有可能是正常现象，所以我们工程师建议您编译一下一个未修改的simple_central的示例，看看SimpleCentral_scanCb()话会不会跑飞。我们也会持续跟进您的问题。

您也可以参考一下https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_6_20_00_29/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index.htm

,

z yy：

编译过了，未修改的simple_central示例里面没有调用GapScanner_enable()不会进入SimpleCentral_scanCb()，只要不开启扫描就是正常的

,

Nick Sun：

您好，

帮您同步工程师，请稍等，感谢您的支持。

,

z yy：

请问有调试方法了吗

,

Nick Sun：

您好，

这是在英文论坛帖子链接。

您可以看一下Clément的相关回复是否能够帮助到您。

后续有什么需要直接回复的您可以和我说，可以帮您回复。

,

z yy：

只要调用GapScan_enable()程序就会陷入无响应的状态，如果不调用GapScan_enable()程序就可以正常运行

,

Nick Sun：

您好，已帮您同步消息。

感谢您的等待。

,

Nick Sun：

您好，

我们工程师表示无法在未修改的示例上重现您的问题，所以无法具体展开研究您的问题。如果您有更多信息或者是对the out of the box examples存在问题的更多证明，您可以新开一个帖子，此帖将被关闭。

在所有情况下，都请避免在程序中回调潜在的阻塞函数（please avoid executing potentially blocking function calls in callback contexts）。

感谢您的理解。
