关于CC3200低功耗问题
运行环境：
CC3200成功连接路由器后，使用lp3p0_setup_power_policy(POWER_POLICY_STANDBY)函数让CC3200进入低功耗，定时器作为唤醒源，程序是运行在我们自己开发的以CC3200为主控芯片的硬件上，外围模块均已断电。
问题：
1. 设备连接上路由器后，然后让设备处于低功耗，不关闭路由器
我们的硬件电流会在1ma - 几时毫安波动，虽然电流更多的是处在1ma。我们也测试了ti官网提供的例程idle_profile电流也会波动，请问这是什么原因。
2. 设备连接上路由器后，然后让设备处于低功耗，然后关闭路由器
此时设备电流稳定在1ma，如果从新开启路由器，那么设备的电流有会出现波动，这种情况下，经过多次测试电流有时候会停留在10多毫安不变，有时候会1ma到 十多毫安波动，请问这是什么原因？
备注：我们的目的是，让设备稳定在1ma，然后等定时器唤醒。
应该是电路问题，如果用官方的例子也这样，肯定是电路设计的问题

//(2)测试M4-core进入LPDS+NWP连接AP不发数据整体平均功耗=1mA左右,甚至在800uA附近，万用表一直在波动无法准确确定
// 实际观察万用表发现在M4进入LPDS后，其实也没有数据发送仅仅是AP连接，功耗多数在1mA之上，甚至几个mA,但是过大约几min后，功耗稍微
// 降低了一些大约在600~800uA波动，也会有2~3mA的峰值出现，可能是NWP判断当前没有数据活跃后进入了相对省电的模式。
