TI中文支持网由TI 标准例程\simplelink_cc2640r2_sdk_2_20_00_49\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral修改而来。
删除了CC2640R2_LAUNCHXL，增加了CC2640R2DK_4XS，Display_DISABLE_ALL。按键驱动程序改为如下：
#define Board_BTN1 CC2640R2DK_4XS_KEY_UP
#define Board_BTN2 CC2640R2DK_4XS_KEY_DOWN

// Set the Peripheral GAPRole Parameters
GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t),

}
}
else if (keys & KEY_DOWN)

// Set the Peripheral GAPRole Parameters
GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t),

}
}
}
问题如下;
刚烧录完这两个按键可以正常启动和关闭蓝牙。
按下复位键之后，两个按键就不能正常工作了。不能唤醒。
请问下这是怎么回事呢？谢谢！
