无法通过内部代码配置Movesense双击参数，寻求技术协助

问题背景 #

开发Movesense设备的双击事件功能时，效果不理想，确认通过配置以下内部寄存器可优化效果：

• doubleTapDur
• doubleTapQuiet
• tapThs
• axes

通过Movesense Showcase ADB桥接APP使用ADB命令可正常读写这些参数，但自行编写的DoubleTAPConfig()函数设置参数时无法生效，需排查原因。

有效ADB命令 #

读取参数命令 #

adb.exe shell am broadcast -a "android.intent.action.MOVESENSE"  --es type get --es path Component/LSM6DS3/TapParams --es value '''{}'''

写入参数命令 #

adb.exe shell am broadcast -a "android.intent.action.MOVESENSE"  --es type put --es path Component/LSM6DS3/TapParams --es value '''{\"newParams\":{\"doubleTapDur\": 8, \"doubleTapQuiet\": 3, \"tapThs\": 8, \"axes\": 8}}'''

排查方向 #

1. 添加异步请求结果回调：当前代码仅调用asyncPut但未处理请求结果，需实现onPutResult方法捕获错误信息，排查参数是否提交成功：

void DOUBLETAP::onPutResult(wb::RequestId requestId, wb::ResourceId resourceId, const wb::Value& result, const wb::Error& error)
{
    if (error.code != wb::HTTP_CODE_OK)
    {
        DEBUGLOG("Put TapParams failed! Error code: %d, message: %s", error.code, error.message.c_str());
    }
    else
    {
        DEBUGLOG("TapParams updated successfully");
    }
}

2. 匹配参数结构格式：ADB命令中参数包裹在newParams对象内，代码直接传递TapConfig结构体可能不符合资源要求，尝试构造包含外层newParams的Value对象：

wb::Value tapValue;
tapValue["newParams"] = TapConfig;
asyncPut(WB_RES::LOCAL::COMPONENT_LSM6DS3_TAPPARAMS(), AsyncRequestOptions::Empty, tapValue);

3. 确认资源路径正确性：核对WB_RES::LOCAL::COMPONENT_LSM6DS3_TAPPARAMS()是否与ADB使用的Component/LSM6DS3/TapParams资源端点完全映射。

4. 调整配置调用时机：startModule中调用DoubleTAPConfig()时传感器可能未完成初始化，尝试延迟调用或在传感器就绪事件触发后再配置参数。

5. 移除错误的资源调用：注释中的COMPONENT_LSM6DS3_WAKEUP()资源与TapParams为不同端点，无法混用TapConfig结构体，需删除该尝试代码。
