CC2640R2L: 定时器异常

我需要实现使用两个定时器进行广播切换的功能，在定时器A的事件触发时进行自定义广播包的切换，在定时器B事件触发时，进行标准广播包的切换，并循环持续30s，但是当第一个广播包切换后，定时出现异常，且其他的触发事件都出现了异常，例如串口，按键，都无法触发了，请问这是什么情况导致的。

我的代码如下：

#define SP_ADV_SOS_EVT_PERIOD300
advInt = 160


Util_constructClock(&advsos, SimplePeripheral_clockHandler,SP_ADV_SOS_EVT_PERIOD, 0, false, (UArg)&argadvsos);
Util_constructClock(&advupade, SimplePeripheral_clockHandler,advInt * 0.625, 0, false, (UArg)&argadvupade);


static void adv_init()
{//Method 1if (sos_state == 1)memcpy(updateAdvData, advertDataNew, sizeof(advertDataNew));else if(sos_state == 0)memcpy(updateAdvData, advertData, sizeof(advertData));bStatus_t status = FAILURE;status = GapAdv_prepareLoadByHandle(advHandleLegacy,GAP_ADV_FREE_OPTION_ADV_DATA);SIMPLEPERIPHERAL_ASSERT(status == SUCCESS);// Load advertising data for set #1 that is statically allocated by the appstatus = GapAdv_loadByHandle(advHandleLegacy, GAP_ADV_DATA_TYPE_ADV,sizeof(updateAdvData), updateAdvData);SIMPLEPERIPHERAL_ASSERT(status == SUCCESS);//Method 2

*/
}

static void SimplePeripheral_processAppMsg(spEvt_t *pMsg)
{bool dealloc = TRUE;switch (pMsg->event){...case SP_ADV_SOS_EVT:sos_start_handler();break;case SP_ADV_UPDATE_EVT:adv_start_handler();break;default:// Do nothing.break;}
}

static void sos_start_handler(void)
{flag_status.adv_clock_ticks++;Util_startClock(&advsos);if (flag_status.adv_clock_ticks == 50){Uart0_Write("Stop\r\n", 6);flag_status.adv_clock_ticks = 0;GapAdv_disable(advHandleLegacy);sos_state = 0;adv_init();Util_stopClock(&advsos);Util_stopClock(&advupade);}else{Uart0_Write("sos\r\n", 5);sos_state = 1;adv_init();}
}

static void adv_start_handler(void)
{Uart0_Write("adv\r\n", 5);Util_startClock(&advupade);sos_state = 0;adv_init();
}

如果我把代码中的adv_init()屏蔽以后，在定时器事件中添加串口log，发现定时器可以进行触发，其他事件也可以正常进行。

您好，

请问该问题有答复了么

Nick Sun：

您好，

我们认为不能多次“创建” advertisement set，我们建议只调用一次函数“GapAdv_create()”，并且只更新在User's Guide中提到的广播数据（advertising data）。

您还需要考虑使用两个advertising sets的情况下，每个advertising sets将根据定时器来启用/禁用。

希望能够帮助到您。

Jinxin Zhang：

谢谢您的解答，我使用该方法更新数据是可以正常工作的：

static void adv_update()
{GapAdv_disable(advHandleLegacy);if (sos_state == 1)memcpy(updateAdvData, advertDataNew, sizeof(advertDataNew));else if(sos_state == 0)memcpy(updateAdvData, advertData, sizeof(advertData));GapAdv_prepareLoadByHandle(advHandleLegacy,GAP_ADV_FREE_OPTION_DONT_FREE);// Load advertising data for set #1 that is statically allocated by the appGapAdv_loadByHandle(advHandleLegacy, GAP_ADV_DATA_TYPE_ADV,ADV_UPDATA_LEN, updateAdvData);GapAdv_enable(advHandleLegacy, GAP_ADV_ENABLE_OPTIONS_USE_MAX, 0);}

您好，

很高兴您的问题又被解决。感谢您的支持。
