Smartbond IOT sensor - Accelerometer range

Hi Jyro_gr,

The available maximum data rate for the application is 100Hz, the sensor can support up to 1600Hz, but the sensor fusion implementation can't handle that fast update rate so there isn't any implementation for higher data rate. Same for the gyro as well the sensor can support up to 3200Hz data rate but not the application.

谢谢mt_dialog.

Hi Jyro_gr,

Its not only the sensor fusion, the limitation is valid for the raw project as well, since in higher rates of data generation the BLE is not going to be capable of transfering the data over the link one interrupt at a time. The higher data rates require connection intervals that are out of the minimum connection interval allowed by BLE. The minimum allowed is 7.5 and for 100Hz data rate we use about 10ms connection interval. You can update the IoT raw firmware through keil in order to get more data during one report (more data packed in a single connection interval) but the application isn't going to be able to follow, there should be a lag on what is displayed in the application and also the device isn't tested in operation that exceed the default data rates.

您可以通过拒绝从默认数组和user_app_wrbl_config中加载数据来测试这一点，然后将sensor_sample_rate_imu更改为用户样本案例，例如sensor_sample_rate_user_case2，并为该样本案例bmi160_accel_output_data_rate_200hz和bmi160_accel_output_data_rate_200hz选择。

谢谢mt_dialog.

Hi,
I am using "SmartBond IoT Sensor Development Kit" for Fusion data. By using "IoT Sensors mobile app", I am able to see the 3D motion on the mobile while rotating the sensor development kit. Presently, I am using other android app (Application specific android app) to rotate the image on the mobile. But I am not able to get the rotation on the android app. I think, I am not following proper procedure and factors to calculate the Yaw,. Pitch and Roll values.

I am able to receive the data of Fusion from the IoT sensor Development kit to my android app. Please guide me in doing the calculation to get the parameter to make the image to rotate on the android app.

问候，

嗨mahesh，

The IoT sends the appropriate data from the senor fusion algorithm to the mobile phone through custom reports that are indicated in the documentation (please check Table 12 in the UM-B-063 document). If your application follows the same conventions as the IoT application you should be able to get some 3D movement. Is your application able to parse the data from the reports of the IoT ? What i can do in order to help is to send you the IoT android/iOS code if you like to use it as a reference.

谢谢mt_dialog.

Hi,
我们的应用程序能够从IOT中解析数据。请Android代码。理解融合数据处理可能有助于。

非常感谢您的快速回复。

Hi,
Thank you for your response. I will update to you.

Hi,
I am using IoT code for DA14583 (version: v5.160.1.19). As per the "UM-B-063_DA14583_IoT_sensor_development_kit_1v1.pdf", It is supporting 4 Modes of operation.

1.陀螺仪，加速度计和磁力计（GAM）模式
2. Gyroscope and Accelerometer (GA) mode
3.仅陀螺（g）模式
4. Accelerometer and Magnetometer (AM) mode

请指导我了解配置模式的过程。我可以在代码中更改操作模式。

问候，

嗨mahesh，

您的设备中启用了哪些传感器取决于Sensor_Config变量，该变量是从user_sensor_config.c文件中的默认值的默认值或直接从非易失性存储器中填充，Scentry的Scrent_Combination成员是其中一个控制要启用的传感器。默认值是enabent_all_sensor_flags。代码将检查user_init_sensor_combination中设置哪些标志，并将启用相应的传感器。

谢谢mt_dialog.

Hi,
您所说的是用于启用传感器。

Could you please explain the procedure, so that while calculating the sensor fusion the IoT hardware only uses Gyroscope and Accelerometer data.

请指导我如何继续。

问候，
Mahesh Chandana

嗨mahesh，

您的问题是如何在可用选项（GAM，GA，G，AM）之间的代码中配置操作模式。通过启用传感器，设备将通过启用的传感器提供具有适当数据的传感器融合引擎。有关IOT功能的更多信息，您可以在7.3节中检查UM-B-063，其中在系统的每个不同状态下详细描述了一般操作。
