我正在为 Microsoft Band 开发 UWP 应用程序,最近从 Band SDK ver 1.3.11121 升级到 Microsoft Band SDK ver 1.3.20115。
我注意到,如果我订阅了多个传感器(包括 Altimeter 传感器)的 ReadingChanged 事件,一旦 Altimeter 传感器首次报告数据,我就不会收到任何传感器(包括 Altimeter)的数据。
我有简化版的代码,但我仍然可以看到问题所在:
IBandClient bandClient;
async void SetupBand()
{
IBandInfo[] pairedBands = await BandClientManager.Instance.GetBandsAsync();
try
{
bandClient = await BandClientManager.Instance.ConnectAsync(pairedBands[0]);
if (bandClient.SensorManager.Gyroscope.GetCurrentUserConsent() != UserConsent.Granted)
{
await bandClient.SensorManager.Gyroscope.RequestUserConsentAsync();
}
if (bandClient.SensorManager.Altimeter.GetCurrentUserConsent() != UserConsent.Granted)
{
await bandClient.SensorManager.Altimeter.RequestUserConsentAsync();
}
IEnumerable<TimeSpan> supportedAltimeterReportingIntervals = bandClient.SensorManager.Altimeter.SupportedReportingIntervals;
TimeSpan T1 = supportedAltimeterReportingIntervals.First();
bandClient.SensorManager.Altimeter.ReportingInterval = T1;
IEnumerable<TimeSpan> supportedGyroscopeReportingIntervals = bandClient.SensorManager.Gyroscope.SupportedReportingIntervals;
TimeSpan T2 = supportedGyroscopeReportingIntervals.First();
bandClient.SensorManager.Gyroscope.ReportingInterval = T2;
bandClient.SensorManager.Altimeter.ReadingChanged += (sender, args) =>
{
System.Diagnostics.Debug.WriteLine("Input received for Altimeter");
};
bandClient.SensorManager.Gyroscope.ReadingChanged += (sender, args) =>
{
System.Diagnostics.Debug.WriteLine("Input received for Gyroscope");
};
await bandClient.SensorManager.Gyroscope.StartReadingsAsync();
await bandClient.SensorManager.Altimeter.StartReadingsAsync();
}
catch (BandException ex)
{
// handle a Band connection exception
}
}
- 通过上面的代码,我看到了陀螺仪传感器的大量更新,但是一旦高度计传感器报告了数据,陀螺仪和高度计的所有进一步数据报告就会停止。
- 代码显示了调试和发布(使用 .Net Native 编译器工具链)构建的问题
- 如果我使用 Microsoft Band SDK 1.3.11121,此代码可以正常工作,但不适用于 SDK 1.3.20115。
我是否在代码中遗漏了什么或做错了什么?
最佳答案
已确认这是一个问题。此问题现已在 SDK 版本 20217 中修复。
