[参考译文] CC2640R2L：定时器异常。

https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1134675/cc2640r2l-timer-exception

大家好、

以下是客户的请求：

他希望使用两个计时器来实现广播切换的功能。  触发计时器 A 事件时切换自定义广播包、触发计时器 B 事件时切换标准广播包、 并循环30秒。

但是、当第一个广播包被切换时、时序异常、其它触发事件也异常 、例如串行端口和按钮。

发生了什么以及 如何修复。

代码如下图所示：

#define SP_ADV_SOS_EVT_PERIOD                300

                      advInt * 0.625, 0, false, (UArg)&argadvupade);
