cc2640r2f中从机调用GATT_Notification(0,req,false);这个函数给主机发数据，会导致从机重启吗？

不会。

谢谢回答

你可以使用simpleperipheral 去测试一下,在 SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR4, sizeof(uint8_t),本质上是notify
&valueToCopy);
static void SimplePeripheral_performPeriodicTask(void)
{
uint8_t valueToCopy;

// Call to retrieve the value of the third characteristic in the profile
if (SimpleProfile_GetParameter(SIMPLEPROFILE_CHAR3, &valueToCopy) == SUCCESS)
{
// Call to set that value of the fourth characteristic in the profile.
// Note that if notifications of the fourth characteristic have been
// enabled by a GATT client device, then a notification will be sent
// every time this function is called.
SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR4, sizeof(uint8_t),
&valueToCopy);
}
}
