lock.locked() Return the status of the lock:Trueif it has been acquired by some thread,Falseif not. In addition to these methods, lock objects can also be used via thewithstatement, e.g.: import_threada_lock=_thread.allocate_lock()witha_lock:print("a_lock is locked while this execut...

休眠锁本质上也是一个flag,允许创建多个。生效机制是:只要有任意一个休眠锁处于lock状态,模组就不会进入休眠。 使用方法参见:创建wake_lock锁 影响蜂窝通信模组休眠的因素# 底电流# 影响底电流的功耗的原因主要是系统的主频、打开的IP核的功耗,这块和PMIC 相关。
