一、摘要
| UWB功耗点 | 插桩点 | 日志关键字 | 电流 |
| 蓝牙持锁 | BatteryStats的锁统计 | vendor_bluetooth_lock | 30~40mA |
| 测距 | UwbSessionManager.startRanging UwbSessionManager.stoptRanging 或接入fadiKey Uwb状态广播 "com.fadiui.dkservice.action.uwb.state.change" | startRanging|stopRanging|UwbUciCore | 60~90mA （无持锁测距~持锁测距） |
初步结论：可行，加下代码，后面实测下是否正确触发。
UWB 命令集：
adb shell dumpsys uwb
adb shell cmd uwb help
二、UWB架构
2.1 UWB 堆栈架构
UWB 堆栈由 UWB Mainline 模块和 UWB 芯片供应商提供的 HAL 实现组成。
2.2 UWB framework
三、功耗相关日志
