Is there a way to get collective permission for multiple Data points from Healthkit

Asked 2021-May-12 at 03:18

I am creating an application which needs to fetch heartRate, restingHeartRate, walkingHeartRateAverage, HeartRateVariabilitySDNN data from HealthKit.

Also I want to fetch user's body measurement data. i.e body mass index, body temperature, height, waist circumference, weight.

To get read permission I need to get separate permission for each data type:

...

ANSWER

Answered 2021-May-12 at 03:18

Each HealthKit type must be authorized independently:

To help protect the user’s privacy, HealthKit requires fine-grained authorization. You must request permission to both read and share each data type used by your app before you attempt to access or save the data.

https://developer.apple.com/documentation/healthkit/authorizing_access_to_health_data

Apple foresaw the difficulty of asking for many HealthKit types at once, and suggests to ask permission for different permission types at various times in your app rather than all at once:

However, you don’t need to request permission for all data types at once. Instead, it may make more sense to wait until you need to access the data before asking for permission.

The HealthHit permission dialog also does have a single button that allows the user to enable all requested types:

There are two options, either we can use resample or pd.Grouper(which is performant).

You can use StreamBuilder for this. StreamBuilder widget is mainly made for this only. It takes mainly 2 parameters, first is stream and other is builder. StreamBuilder listens for the change in stream and builder builds your UI then.

Android Studio could not open COM port with chaquopy python

...

ANSWER

Answered 2021-Mar-26 at 13:46

"COM4" looks like a Windows serial port name, so that won't work on Android. Try using something like serial.tools.list_ports to discover the correct name.

Also, even if you do use the correct name, your app probably still won't have permission to access the port directly. If you're running on a rooted device, you may be able to get pyserial to work by changing the permissions on the port's device file. On non-rooted devices, the only option I know of is to use the Java UsbManager instead, perhaps with the help of a library like UsbSerial. You can still call these APIs from Python with the help of the Chaquopy Python API.

Web Bluetooth: Can't pair BLE device with Mobile Device with Live Server VS Code extension

Asked 2021-Mar-23 at 13:57

I'm a beginner in the Web Development world. I want to pair a BLE device (NRF52840 DK) with my mobile device through a web page. I tested an example for Web Bluetooth and it works fine on my PC as you can see on the following image:

Pairing my PC (Chrome) with a BLE device successfully

I did it through the popular extension Live Server on VS Code. When I tried to access to that page on my mobile (Android) using my IP and port, and pressed the button nothing happened.

ANSWER

Answered 2021-Mar-23 at 13:57

I don't think it's possible in the way you describe it. Web Bluetooth only works on pages which has HTTPS enabled. It works on localhost too for testing purposes. Since you access the web application via an IP-address which doesn't have HTTPS enabled, Web Bluetooth is not available.

https://web.dev/bluetooth/#https-only

You can test this by adding a text to the page with a boolean or other text which will show if web bluetooth is available.
