UWB功耗大数据插桩调研

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

3.1 蓝牙持锁日志

日志关键字:vendor_bluetooth_lock
