如题,启动后广播30s然后关闭广播,只能进入PM2,电流还有150uA左右,请问还有什么事件没关闭吗?另外连接时功耗500uA左右,用官网的keyfobdemo连接时能做到10uA以下,源码如下:

参数看下,你可以比较一下官方keyfobdemo 和你程序这部分的差别
主要是 连接间隔时间 广播间隔时间 等参数
时间久了 记不得了
无线的功耗主要在radio work time
连接时间这个参数会影响通讯速度,一般建议设置的大一些,功耗可以明显下降。
@lyzhangxiang 感觉没有对比性啊,官方用的是Proximity Reporter Profile,而我用的是Simple GATT Profile。而且我用我的初始化放到官方例程上功耗也是降不下来
是不是开启了定时器没有关 只能PM2
我说的这些参数
随便什么profile都有的,这个属于基本的radio参数
问题解决了,参数设置都没有错,只不过不能把HAL_LED=TRUE定义为FALSE,不能关闭LED,不知道为什么
